The Magic of Butterflies and Moths is a new Moon Books title

The Magic of Butterflies and Moths is my new book


The Magic of Butterflies and Moths is my latest book published by Moon Books. It will be available on 24 February 2023, but it can be preordered now. As the title suggests I take a look at what can be considered as magical about these amazing insects. Everyone is familiar with the incredible transformation from egg to caterpillar to chrysalis and then to adult butterfly but there are many more astounding facts about butterflies and moths. 

Swallowtail caterpillars

I first became fascinated by these insects when I was a little boy. I used to keep caterpillars in jam jars and other containers. I learned then that you had to feed the larvae with the right types of plants. I also learned that some chrysalises and pupae have a short time before they emerge as adults, while others must wait many months and go right through the winter and the spring months before eclosing in early summer. Many species of butterfly and moth embark on lengthy migrations at specific times of the year. They can fly incredibly long distances and cross seas. The Monarch is probably most famous of all for its annual migration from the lower part of Canada and the most northerly American states right down to Florida, California and Mexico. It overwinters in the south and in the spring it begins the migration northwards. 









Monarch butterfly

I take a look at butterflies that live in the most inhospitable areas where you would probably think these insects cannot be found. But there are butterflies that live within the Arctic circle, in Lapland and Siberia. Some butterflies have extraordinary life cycles. There are species of Blue butterfly that depend on specific species of ants finding their caterpillars. The ants take the caterpillars into their nests where when fully grown the butterfly larvae become chrysalises. The very rare Large Blue is a species that is like this. 

Many species of butterfly and moth employ elaborate camouflage as adults and as caterpillars to help protect them from predators. When their wings are folded some species look like dead leaves as adults, some caterpillars look like twigs. Other types have displays and warning colours of bold contrasting hues that are a signal that says “do not eat me because I will poison you!” There are moth species that cannot feed as adults, there are many others in which the females are not only unable to eat but they cannot fly either. Yet the caterpillars of these species are some of the most gaudy and exotic looking of all. Some moths, such as the weird looking Death’s-head Hawk-moth have become the subject of superstitions. Because it has an odd skull-like marking on its thorax and because it has weird behaviour such as the ability to squeak, this moth was regarded as a bad omen. 









Death's-head Hawkmoth

As well as the appearances and behaviour of many species of butterfly and moth I take a look at what we can do to help them. There is a chapter devoted to butterfly gardening, as well as a list of some organisations where you can find out more about butterfly (and moth) conservation. 

The Magic of Butterflies and Moths has some wonderful endorsements from people such as Rebecca of Rebecca’s Butterfly Farm who said: “Lovely stories and lots of amazing facts.” Paul Hetherington, Buglife Director of Fundraising and Communications described my book like this: “The Magic of Butterflies and Moths is just what is needed to help people understand and have friendlier relationships with these incredible insects, a major goal of our No Insectinction campaign.” 

My book will be available from Amazon.com and Amazon.co.uk as well as many other book suppliers around the world. Just Google “Steve Andrews The Magic of Butterflies and Moths” and pick up your copy.

Butterflies flying in March in Portugal

Butterflies flying in March in Portugal

There are many butterfly species currently flying in the area of Portugal I live in. They are enjoying the warm spring sunshine. I saw several Green Hairstreaks (Callophrys rubi), two Clouded Yellows (Colias crocea) , two Red Admirals (Vanessa atalanta),

lots of Speckled Woods (Pararge aegeria aegeria) and several Large Whites (Pieris brassicae) on a short walk today. As well as these butterflies, I spotted two Spanish Festoons (Zerynthia rumina). I live in Quinta do Conde and like to walk through some forest and scrub on my way to the local supermarket and back. I usually see butterflies unless it is very cold, wet or windy. There are plenty of plants the Green Hairstreak butterflies can lay their eggs on here. They have a choice of Gorse (Ulex) or the Rockrose (Cistus) species. I was watching a Clouded Yellow female carefully searching in a short grassy area for Clovers and Medicks that are sprouting after some recent rains. Like all butterflies, the success of a species is very much linked to the distribution of plants they need for their caterpillars, and how well these plants are growing at the right season. Even if the correct plants are available in a given area, heat and drought can shrivel them up or prevent them growing at all. This is a disaster for a female butterfly. Every year we get several months in the summer period when the vegetation mainly goes brown or dies back to the ground. It can even be difficult finding some green blades of grass.

This is a big problem for the butterflies, like the Speckled Wood and Meadow Brown (
Maniola jurtina), that have larvae that feed on grasses. The latter butterfly flies later in the year and does surprisingly well here, though I have seen them sheltering in the shade of trees when it is very hot. I always wonder how they find enough grass to lay their eggs on. For the Speckled Wood in February and March this is not a problem because the grass species grow back after the winter rains. This year there has been a terrible winter drought so the land is very dry. Nevertheless many plants, including grass species, have survived, though they are nowhere near the usual size. I have been especially glad to see the small colony of the Spanish Festoon is still thriving. Last year, I didn’t see any of this species and feared that the brutal cold of the winter of 2020-2021 had wiped them out. I was obviously wrong because I have seen several of this species in the area they are found in here. Speaking of the Spanish Festoon, and its potential problems, it took me years to find the food-plant they are using in my locality. The Spanish Festoon needs any of the species of Birthwort (Aristolochia).
The species that grows here is the Round-leaved Birthwort (
A. rotunda). It is a delicate plant that winds its way amongst bushes and undergrowth so is not that easy to spot, especially in shaded areas. It only grows in one part here, where it is found in a lightly wooded area with a pathway and a bank. I can see for myself how this species is bound to stay where its food-plant grows because every year this location is the only place I can find this spectacular butterfly. I say spectacular because its wings are marked with darker zigzags and red dots on a yellow background. I am a migraine sufferer and the jagged lines remind me of the aura formation many people who get migraines are used to seeing.
Horrible as migraines are, the Spanish Festoon is a truly beautiful species of butterfly.

Helping the Red Admiral Butterflies

Red Admirals need Nettles

Red Admiral Photo: Steve Andrews

The Red Admiral (Vanessa atalanta) is a very pretty butterfly you are probably familiar with. You can’t miss it with its striking red, black and white wings, and in the UK, it is one of the last butterflies to be seen in late autumn. We all love to see butterflies but many people don’t realise how important the plants the caterpillars need to feed on are. In the case of the Red Admiral, the main food-plants are Nettle species. The Stinging Nettle (Urtica dioica) is the most commonly used plant but here in Portugal where I live, the Annual Nettle (U. urens) is the species they use.

Annual Nettles Photo: Steve Andrews
These nettles spring up as a garden weed and on waste ground in the autumn and winter when rains fall. Sadly because they are regarded as a weed, many people destroy them, either manually with care, due to the stinging threat from the plant, or with herbicide, and any Red Admiral eggs, caterpillars or chrysalises, get destroyed too. 
I saw a large patch of Small Nettles growing on some rough ground in a shortcut between two roads in my neighbourhood. I checked for Red Admiral caterpillars and soon found some, which I took into care, just in case anyone came along and killed the plants. I am very glad I did because some council workers turned up and removed all the vegetation that was growing there.
There is a skill to finding Red Admiral caterpillars, but it is very easy to learn. The caterpillars are usually found towards the top of a nettle stem and they fold leaves around themselves as shelters. The leaves are held with a small amount of caterpillar silk. They eat surrounding leaves and you can spot the holes in these leaves and their ragged appearance where they have been eaten away.

Sometimes the Red Admiral caterpillar will pupate inside their shelters too, but not always, because they will also transform into chrysalises that hang suspended from nettle stalks or possibly on a wall, fence or other object near where the caterpillar has been feeding.
I keep the caterpillars in sandwich boxes with a paper towel on the bottom to help absorb any dampness and to make it easier when cleaning out the container and providing new food. Often I find that the caterpillars will choose to pupate after spinning a pad of silk on the plastic top of the sandwich box. The chrysalises are brown but some are speckled with gold. As the butterfly inside becomes more developed and nears the time for emergence it becomes much darker and you can see the wings colouring up in the wing-case on each side of the chrysalis.

When the Red Admirals finally emerge, or eclose, as lepidopterists would say, they need to dry their wings thoroughly before they take their first flight. It is very important at this stage that they are not disturbed and that they don’t fall off whatever they are clinging to. This can be a problem for all species of butterflies at this stage of their life-cycles. Fallen butterflies can become cripples if they fail to expand and dry their wings properly. Usually all goes well, though, and the Red Admiral is all set to fly away. This butterfly can fly a long way. Many of those seen in the UK are migrants, though this species can hibernate in Britain too. In Portugal they have more than one generation but need nettles. I usually see them in autumn, winter and spring. In summer it is too hot and dry. There is a place in some woodland near where I live that I can almost guarantee I will be able to find a male Red Admiral every year in the right seasons. Of course, it isn’t the same butterfly but is obviously an ideal spot for a male of this species to create a territory he can patrol.

Butterflies in December in Portugal

 Butterflies still flying in December

Red Admiral (Photo: Steve Andrews)

Here where I live in Portugal there are still butterflies flying in December. One of the most commonly seen is the Red Admiral (Vanessa atalanta).  The males establish territories they patrol on scrubland, while mated females seek out patches of Annual Nettles (Urtica urens) that grow well at this time of year, due to the late autumn rains. These nettles often grow as weeds in gardens and so the butterflies can often be seen there too. The caterpillars make tents out of the leaves and can be found by looking rolled up leaves at the top of plants. There is a patch of ground where I took the photo above, where I see Red Admirals every year. It is almost as if the same butterfly has returned, as regular as clockwork, but of course, they are new butterflies. This leaves the question of how do they select the same spot each year. It is amongst scrub and pines but there are plenty of similar spaces. 

Small White (Photo: Steve Andrews)

The Small White (Pieris rapae) can often be seen too in December. I presume the Large White (P. brassicae) are still around, though I cannot vouch for this. although at other times in the year they are common. Both species can be seen in urban settings where they fly over parks and gardens in search of cabbages, cauliflowers, kale and broccoli on which their caterpillars can feed unless gardener spots them and removes them. Both species can be found in rural areas too where the females lay their eggs on wild species in the Cress family (Cruciferae). 

Speckled Wood (Photo: Steve Andrews)

There are still a few Speckled Wood butterflies about as well. The subspecies most often seen Portugal is Pararge aegeria aegeria. The speckles on its wings are more of a tawny orange shade than the usual pale yellow markings that contrast with the darker brown. At first sight these Portuguese Speckled Woods closely resemble the Wall Brown (Lasiommata megera), and I must admit I was fooled by this similarity when I first came to Portugal. The Wall Brown has seriously declined in the UK. Both these butterflies use various grass species as food-plants for their caterpillars. Here in Portugal I always wonder what the butterflies that need grass do in the hot part of the year when all the grass has died or become dessicated and brown. They have some means of surviving these times of summer drought. The Meadow Brown (Maniola jurtina) is very common where I live, which is in a town about 25km south of Lisbon. It is not seen in winter but when it does fly in summer I have seen these butterflies sheltering in the shade of clumps of trees. 

Swallowtail caterpillars on Rue (Photo: Steve Andrews)

There are still caterpillars of the Swallowtail (Papilio machaon gorganus) feeding on Rue in gardens, though I haven't seen any adult butterflies since November. The winter chrysalises of this species are a brownish colour, as opposed to the green ones that are produced for the rest of the year. These chrysalises and any still to be produced, will stay sleeping until the spring when the cycle begins again. Speaking of Swallowtail butterflies,  I saw a female of the Southern Scarce Swallowtail (Iphiclides feisthamelii) in the first week of December, despite the cold.  She was inspecting an almond tree on some waste-ground near where I live and laying her eggs on the remaining leaves. Sadly her efforts were in vain because the tree has since shed all its leaves. I went back to see if could spot any caterpillars that had hatched, with the idea that maybe I could keep them indoors and feed from any leaves I could locate on plum, peach or almond that hadn't yet dropped theirs. There were no leaves and no caterpillars. This female butterfly was out too late in the year here.  Many species are being affected by climate change and are doing what they can to adapt to the ever changing conditions we are experiencing. Next month is usually the coldest month of winter in Portugal and we get hard frosts then so I am not expecting to see any January butterflies but these days you never know!

Searching for Birthwort with the Spanish Festoon Butterfly

Searching for Birthwort with the Spanish Festoon Butterfly

Spanish Festoon (Photo: Steve Andrews)
The Spanish Festoon (Zerynthia rumina) is a very pretty butterfly in the Papilionidae or Swallowtail butterfly family. It has strikingly patterned wings of yellow, red and dark brown with zig-zag markings on its hindwings. It is found in Spain, Portugal, North Africa and southern France. I have seen the butterflies in scrubland and pine and oak forest near where I live, but until today I have never seen any of the Birthwort species (Aristolochia spp) this butterfly uses as food-plants for their caterpillars.

I have lived in Quinta do Conde in Portugal for the last five years but have never managed to find any type of Birthwort growing here so it has been a real mystery for me, as to how these butterflies survive here. Today after a lot of searching, I discovered a clump of Round-leaved Birthwort (A. rotunda) growing amongst trees and heather at the top of a bank.
Spanish Festoon habitat (Photo: Steve Andrews)

I had to climb up to find it, and this is why I had never seen it before, although I often walk through this part of the woodland. A female Spanish Festoon has to find this plant or other Birthwort species on which to lay her eggs. There are no other options. The distribution of the food-plants, as is the case with most butterflies and moths, is one of the main factors responsible for the distribution of these insects. In fact, if you find a colony of a particular butterfly or moth, you can be fairly certain that the plants the larvae of that specific species need will be growing nearby. 
Round-leaved Birthwort (Photo: Steve Andrews)

The Spanish Festoon is flying very early this year. Most sources say that it can be seen from April onward, although the excellent Collins Butterfly Guide, which says this butterfly flies from late March to May, also points out that it has been recorded in February. With the Climate Crisis making the weather a lot warmer, and leading to droughts and the very real danger of forest fires in Portugal, butterflies and other species of flora and fauna are directly affected by changes in the weather. 
The Birthwort species are poisonous plants that are dangerous for humans to consume, because poisoning from these plants can lead to kidney failure. These plants were once used to cause uterine contractions, hence the name “birthwort,” but their usage as a medicinal herb has mainly been abandoned due to the dangers of the toxins these plants contain. For the caterpillars of the Spanish Festoon, as is the case with the larvae of many butterflies that have poisonous food-plants, the poisons in the plant become a form of defence for the caterpillars. Because they become toxic too, any predators that try eating them are likely to get very sick. The European Birthwort (A. clematitis) is the species I was expecting to find, so I was pleasantly surprised to find the Round-leaved Birthwort was the local species. Birthworts tend to be straggling plants that need other vegetation or support to climb over. The Aristolochia species have unusual tube-shaped or pipe-shaped flowers, and one species, the Dutchman’s Pipe, which has very large and attractive blooms, is grown for ornamental purposes.

My Protest Songs and Songs About the Environment

With the ongoing Climate Crisis and serious threat of extinction for so many species I have been writing and performing protests songs and songs that draw attention to the environment and to dangers to the wildlife of the world. I have four songs like this on my recent album Songs of the Now and Then, which is released in CD format and as a digital release on bandcamp, and was produced by Jayce Lewis. The CD is environmentally friendly because the tray and packaging is made from recycled eggbox. But now let’s take a look at the songs!
Where Does All The Plastic Go?
Where Does All The Plastic Go? Started life as a poem but I decided to make a song out of it because no one else in the world of music was singing about this problem that affects us all. There is a video made by Filipe Rafael and filmed in Portugal, and this video has had over 19,200 views on Facebook.

My song has been featured in The Portugal News and I was featured on the front page with a caption: “Singing Against Pollution P11.” It has also been featured in a book by Italian radio host and author Filippo Solibello.
In SPAM Stop Plastic A Mare, the author has given a 4-page chapter to it entitled Where Does All The Plastic Go? Filippo has been promoting his book and my song all over Italy and managed to get a copy to Pope Francis. He is also spreading the word about my idea for an Ocean Aid concert, like Band Aid and Live Aid but this time to raise awareness of the crisis at sea caused by plastic pollution , as well as overfishing and other threats to life in the oceans.
I am hoping that this concert will happen and will attract not only big sponsors but very big name bands and singers, who will be willing to take part. Money raised can be distributed to charities helping the oceans. Which ones is yet to be decided on but there are many. Streaming and free downloads of Where Does All The Plastic Go? are available at Reverb Nation.



The Nightingale
The Nightingale, is a song that not only talks about the threat of habitat destruction that is causing a serious decline in this iconic songbird , but talks about the problems caused by development schemes all over the UK and elsewhere. Land-grabs of green belt and forested areas are causing an incredible amount of destruction of the homes of a vast number of species of wildlife. It makes reference too, to the ongoing felling of trees in cities and towns. The song starts with the lyrics: “You’ll never hear a nightingale if their homes are no longer there, destroyed by a developer who doesn’t really care, despite their claims otherwise about biodiversity, ripped up hedges and bulldozed land’s the reality I see.” The Nightingale features vocals from well-known Welsh poet Mab Jones on the choruses. This song is very topical due to all the protests that continue in the UK, where people are trying their best to stop the destruction of the forests and countryside. As I write, there are ongoing demonstrations to Stop HS2, but many more protests are taking place to save the wild places of Britain.
Citizen of Earth
Citizen Of Earth is actually an old song of mine that has been brought up to date with a new recording. I have been aware of the problems the world faces for a long time but everything has got so much worse. This is why I am making protest songs my focus. Citizen of Earth makes reference to the cult TV series The Prisoner, which starred Patrick McGoohan as Number Six. It talks about social unrest and about how people are trapped in a system that is similar in many ways to the Roman Empire. “The Roman Empire was much like today, Patricians and Plebeians and social decay, until the fires burned it all away, the ghost of Nero’s still fiddling. Citizen of Earth has been played on Roque Duarte’s show on the radio in Portugal and has inspired two very different videos. One was made by Ludgero Corvo and the other is an animation by Simon C. Watch them both and see which one you like best!
 

Butterfly In My Beard

Butterfly In My Beard is the most lighthearted of these songs, though it still raises awareness about wildlife, in this case it is talking about butterflies. I rear these insects and the verses of my song refer to real-life incidents. I have had Monarch butterflies on my beard. The second verse goes: “They called me the Bugman on the news one time…. they called me the Bugman on the news, a Hissing Cockroach on my head got plenty of views…” These lyrics are about the time I was in the South Wales Echo in an article about how I kept exotic insects. 
When I perform the song live I get the audience to join in by “making butterflies” with their linked outstretched hands and by giving me a “yeah” at the right places. I am hoping to audition this song in front of the judges of Britain’s Got Talent.

Grass growing after the rain is a help to some butterfly species

After the rains in Portugal

New grass blades - Photo: Steve Andrews

Drought-stricken Portugal has at last had the autumn rains arrive. The land is swiftly going green again. One type of plant that quickly recovers and shoots from dormant seeds is any one of most species of grass. This is wonderful news for many butterfly species that need grass for their caterpillars.
Speckled Wood - Photo: Steve Andrews

The Speckled Wood (Pararge aegeria)  and Meadow Brown (Maniola jurtina) are two widely distributed butterflies that have larvae that feed on grass. Until recently female butterflies were presented with a major problem because most grass had shrivelled and died in the months of hot sunshine and little or no rain. Much of the countryside had become brown and dusty, and what vegetation that survived was tinder dry and in poor condition. However, millions of seeds have been left to germinate after being activated by the next showers of rain. It always amazes me to see how quickly the greenery returns to barren and dried up land that looks more like a desert. Not just grass but countless weeds and wildflowers swiftly cover the ground with their first shoots and seedling leaves. I delight in seeing so much going green again.

Other butterflies

The Small Copper (Lycaena phlaeas) is another butterfly that was sure to have problems in a drought and that I had seen here. Weeks ago there were many specimens of this pretty little butterfly flying on the scrubland and along paths through the woodland. The vegetation under the trees were all dead and brown and I couldn’t find any leaves of the food-plants this butterfly needs. Species of Sorrel and Dock (Rumex spp.) are the plants the female Small Copper must find to lay her eggs on. Sadly, where I live, as far as I could see, none of them were still growing and what was left was either underground or as seeds. I really don’t know what this butterfly does in such conditions and there are no Small Coppers still about here to take advantage of any new growth. If they have somehow survived I will find out next year.

Two more butterflies already returning to the countryside here are Clouded Yellow (Colias croceus) and Small White (Pieris rapae). The former needs species of clovers and trefoils, and the latter looks for plants in the Cabbage family but can also use species of Mustard that grow wild. There should be plenty of food-plants for these butterflies in a while, once the seedlings have germinated and started growing again. This is what is happening here now. All plants that have been laying dormant underground as rootstocks or as seeds on the surface are being activated by the so welcome rains. It is wonderful news too, knowing that more rain is forecast for the rest of the week ahead. We need it!
Because butterfly females lay hundreds of eggs it gives them a far better chance of survival but it is still a mystery to me, as to how they get through periods when there are no green plants of the types they need to be found.

How a Supermarket Shrub Border Could Be A Butterfly Garden

My idea for a butterfly garden at the local supermarket

The shrub border and ground overlooking the supermarket
Every time I go to my nearest Continente supermarket branch here in Quinta do Conde, Portugal, I spend some time looking at the wildlife and plants growing in on a bank that overlooks the store and is planted in parts as a shrub border. Clumps of Lantana when in bloom attract butterflies, bees and Hummingbird Hawk-moths. In my mind it could be transformed easily into a butterfly garden. 
Lantana

But let’s take a look at it as it is now. A lot of the ground gets very dry in hot weather but in wet weather it is covered in weeds. Wall Lizards have formed colonies and can often be seen basking on the concrete around fence posts by the pavement and along poles of wood used to terrace the ground. There is a Weeping Willow that is just about managing to hold its own and is a favourite place for flocks of House Sparrows to perch. Saplings of what looks like some type of Maple have been planted but out of four only one has survived the drought.
Sapling dying from lack of water

It remains to be seen whether the others will sprout now the rains have returned. Millions of ants live in nests in the ground and can often be seen making long trails from one part to another. But it is the butterflies that visit that have got me thinking that with a little bit of work this area could be made into a place where caterpillars could live and complete their transformations into chrysalis and then adult butterflies.The other day I was thinking about this and how all you would need would be a lot of clumps of Rue for the Swallowtails and Milkweed for Monarchs and that both these butterflies would do as well there as they do in the garden where I live. Amazingly, with these thoughts in my head, I was delighted to see a male Monarch and a Swallowtail feeding on nectar from the Lantana bushes. There was also a Small White and Painted Lady doing likewise. Sadly I had no camera with me at the time so couldn’t get photos of any of the butterflies.The Monarch had presumably flown all the way from the house where I live, which is about 15 minutes walk away. When I release butterflies I always wonder where they go. I know a few females always return to lay their eggs on plants I am growing for them but have no way of knowing what happens to the others. I also have no way of knowing if there are any more gardens in this town where Milkweed is grown, though I know there is plenty of Rue because it can be seen in many front gardens.
Swallowtails

I have noted that the local Swallowtails are using the Rue in the gardens in preference to Fennel growing wild in the area. It is obvious why this is. Fennel, although an alternative food-plant for Swallowtail caterpillars, does not do well in the long periods of drought we have been having and it is often without any leaves. As I said earlier, Hummingbird Hawk-moths also feed at times from the Lantanas, though I haven’t seen many this year. It seems clear to me that butterflies and moths do a lot of flying about looking for mates and for food, for themselves and, if they are females, for their caterpillars. If a female Swallowtail had spied the Lantana flowers she might well have stopped to feed, and if she had seen a clump of Rue, she would probably have laid some eggs there. Monarch, Painted Lady, Small White and any other species females would do likewise if the plants their larvae need were growing on the supermarket's land. 
Two female Monarchs on Zinnias in my front garden

There is plenty of ground where other plants could be grown. The Rue would look after itself and is very drought resistant. Just a few clumps of this aromatic herb would result in more Swallowtails there. I could more or less guarantee it. I think it would be good for the public image of the supermarket, if it became known as a store that was helping the butterflies. And this could be done quite easily even though the ground I am talking about is next to a road and carpark. I have recently seen the news that the city of Hull in the UK has become a “Butterfly City,” because it has made the effort to plant many Buckthorns to feed the caterpillars of Brimstone butterflies. This pretty yellow butterfly is limited in its distribution by the availability of its food-plants, which are the Buckthorn and Alder Buckthorn. If Hull can do this so could any other city or town. I hope the idea catches on! Likewise my proposal for a butterfly garden alongside a supermarket could be extended much further. Any businesses or public buildings with land attached to them could have butterfly gardens. Parks and gardens could be improved by simply planting more plants and shrubs that butterflies and moths need. Tragically, the numbers of butterflies and moths worldwide are declining fast. I think this could be reversed if more plants were grown that these winged wonders need. I realise most people would just see some waste ground next to the supermarket and might well think my idea is crazy but that doesn't stop me believing what I have outlined here could work. If can turn out generation after generation of butterflies from a small patch of front garden just think what I could do with all that land! Imagine that: a supermarket with its own butterfly garden! Now how can I make my dream a reality?

The Butterfly Guy

You can call me "The Butterfly Guy."

Steve Andrews The Butterfly Guy in Lisbon

I am becoming known for being a “Butterfly Guy,” because I rear butterflies and share my achievements on social media. I also gave a talk on the subject of Butterfly Gardening to a gardening club in the Algarve a year or so back, and wrote about the subject for Mediterranean Gardening and Outdoor Living magazine. I have a song entitled Butterfly In My Beard and I recently bought a shirt with butterflies all over it. I thought it would be a great public image to have and helps show my love for these amazing insects. Butterfly In My Beard has the lyrics: “They called me a Bugman on the news one time…” and this makes reference to when I was once featured in the South Wales Echo and given this title in a story about how I kept exotic insects.
Bugman Steve Andrews in the South Wales Echo
I first discovered the joys of helping butterflies and moths when I was a little boy and have been doing what I can to help them all my life since then. I used to keep caterpillars in jam-jars, feeding them whatever they needed, watching them transform into a chrysalis or pupa in a cocoon, and then await the day they emerged as a magnificent butterfly or moth. There’s a twofold pleasure gained from rearing a butterfly or moth from egg to adult. First of all there is the joy of seeing the amazing insect in all its glory on its first day as a winged insect, and secondly there is the pride you experience from knowing you helped.

Swallowtails and Monarchs

Swallowtail on my hand


Since I have been living in Portugal I have been rearing Monarch Butterflies (Danaus plexippus) and Swallowtails (Papilio machaon). I find it easy to do and would encourage other people to have a got at helping the butterflies in your area. You just need to grow the plants they need for their caterpillars and provide some flowering plants to provide nectar for the adults.

Female Monarch

I grow Tropical Milkweed (Asclepias curassavica) for the Monarchs and Rue (Ruta graveolens) for the Swallowtails. I have also grown Balloonplant (Gomphocarpus fruticosus) for the Monarchs, and it is a better plant because it grows much bigger. It is also naturalised in some parts of Portugal so is a food source for the caterpillars of the Monarch Butterfly that can be found here. Sadly last winter killed mine plants of it, though my Tropical Milkweeds made it through. 
Tropical Milkweed

Last year I had four generations of Monarchs with on average 30 butterflies eclosing from their chrysalises each time. It has been the same this year and at the time of writing I have about that number of caterpillars here. This will be the last brood for the year. I am running out of plants that still have enough leaves and flowers on them to feed all the hungry larvae and some of the small ones in the garden are going to perish because there is simply not enough food for them. This is a common problem for anyone who goes in for helping the Monarchs. You need to grow a lot of their food-plants. I tend to keep the caterpillars indoors in sandwich boxes or especially prepared large empty plastic water-bottles.
Monarch caterpillars pupating
The latter container I slice through around the middle for easy access, and this can be taped over with sticky tape. I put some tissue in the bottom to catch the frass. I use this method of looking after the caterpillars because I have observed that wasps are a very serious predator that will take away all the larvae they can find on a plant. 
Swallowtails just keep on breeding throughout the year with butterflies flying in every month apart from December and January. They make it through in the chrysalis stage, which remains dormant through the coldest months. Like the female Monarchs, the female Swallowtails return to the garden here because it is somewhere they can lay their eggs. Fortunately for the Swallowtail, Rue is a commonly grown garden plant here. They will also use Fennel and Wild Carrot, but in my experience the caterpillars do not like changing from one plant to another. Where I live most of the Swallowtails are depending on the Rue in local gardens because the Fennel growing wild doesn’t do well in the droughts we have had and loses all its foliage.

The Moths too

Death's-head Hawk-moth


This year, I reared some Death’s-head Hawk-moths (Acherontia atropos) too. I must admit I got the eggs from Worldwide Butterflies, because although I have seen lots of photos and videos of caterpillars of this species shared on social media groups about nature in Portugal, I have not come across them in the town where I live. I used to live in Tenerife and the Death’s-head was a common moth there. I used to find the massive caterpillars on Thornapple (Datura stramonium) and Lantana (Lantana camara). This is a moth species that is lucky to have a very wide range of food-plants, unlike many species that only have a limited range of plants their caterpillars can eat.

I fed my caterpillars on Potato and Privet, which are two of the alternative food sources for the larvae of this magnificent species. This moth gets its name from the marking like a skull on the back of its thorax. It can also squeak and is a very strange but beautiful creature. Unlike its caterpillars, which can eat many types of plant, the adult Death’s-head may have difficulty finding suitable food because it has a very short proboscis. One food it can eat, however, is honey, and this is why it is compelled to enter and rob beehives.
When I lived in the UK I used to keep various moth caterpillars there. I had a lot of success with the Poplar Hawk (Laothoe populi) and Eyed Hawk-moth (Smerinthus ocellatus). I grew a small Sallow tree in the garden and this attracted the female moths. Getting back to butterflies, at the same time in the UK, I had Small Tortoiseshell (Aglais urticae) and Red Admiral (Vanessa atalanta) caterpillars on a patch of Stinging Nettles (Urtica dioica) I had growing. 
That is all you really need to do: grow plants that the caterpillars of butterflies and moths need as food, and provide food for the adults by growing flowers and flowering shrubs. I have Zinnias and a Buddleia/Butterfly Bush (Buddleia davidii), as two of the main attractions for butterflies and moths as sources of nectar. Feed the caterpillars and feed the adult insects and you will have success at helping moths and butterflies.
