Crab spider versus butterflies

29 May 2014

My garden seems to be a dangerous place for butterflies at the moment. I’ve got some periwinkle out, and there is a crab spider hiding in it, which has killed both an Orange Tip and a Wall Brown.

I didn’t realise what was going on at first. I saw the Orange Tip on the periwinkle and just thought “Oh good, another Orange Tip”. It was when I walked past again about an hour later and saw it was still on the same flower that I thought something odd was going on and stopped to have a proper look, and all became clear. This sort of spider likes to lurk in a place likely to be visited by the insects that are its prey, and when they land, will grab them and sink their fangs into the body, injecting them with a venom to kill them, after which it will suck the goodness out of them.

I didn’t like losing the butterfly, but spiders have to eat too. However, I walked past again a week later and spotted a Wall Brown butterfly on the periwinkle. I stopped to take a better look immediately, but mainly because I wanted to verify it was a Wall as this would make it the first one of the year, only to find it was also the victim of the crab spider. Within about half an hour the spider had disappeared and the remains of the butterfly were on the ground. This was rather more upsetting, as the Wall is becoming a less common butterfly: it is disappearing fast from inland areas and only hanging on around the coast.

One final photo, to show you a Brimstone which had the sense to keep away from the periwinkle and stick to the honesty close by – as far as I know, it lived to fly away and maybe mate with a female which will lay eggs on the buckthorn I’ve planted at the far end of the garden: it’s about time one did!

Orange Tips arriving

11 April 2014

After a few not-so-good days, the sun has come out again, and with it the first of the real spring butterflies: the Orange Tip. The male who appeared moved around my forget-me-nots for a while before flying over to a flower on my perennial wallflower (erysimum). He was quite distinctive, having a notch taken out of one wing, presumably by a bird; it is amazing how much wing a butterfly can lose and still keep flying (see my blog from last July for an amazing photo of half a Speckled Wood).

I’d highly recommend the perennial wallflower for attracting butterflies to your garden – this is one which is easy to get, called Bowles Mauve. They tend to flower on and off all year, so they often supply nectar early and late when it is really needed.

The forget-me-nots seem to me to attract more small bees and flies than butterflies, though the butterflies will use it. I’ve got an area of garden I reserve for annuals, and I let the self-seeded forget-me-nots come up under the annuals so I’ve got a show of them for the following spring. It is not really accepted gardening practice, but it works for me – they do form a lovely haze of blue once they get going.

You can see the forget-me-nots in the photo above, behind the red tulips. The purple behind them is a variety of honesty that is confusingly called lunaria annua, so you expect it to be an annual, but actually it is at least semi-perennial, and very easy to grow – it’s name is ‘Corfu Blue’. I’ve also got the perennial honesty called lunaria redeviva, and that is now out (Corfu Blue was out before it), but I don’t think the butterflies like it as much as Corfu Blue.

I’ll leave you with a shot of the garden from the other direction, so you can see the marsh marigolds out in the pond and the two cats by the bench. Happy gardening!

How to identify your butterfly – time of year

12 July 2013

Apologies I missed a blog – have had a virus which drained me of all energy.

One of the things you don’t realise when you are new to looking at butterflies is that each species only flies for a certain length of time each year, and the months in which they fly each year are fairly consistent. A few butterflies may be seen almost throughout the year, notably the Brimstone, which is only absent in the very depths of winter. Others are very limited in the time they spend in the adult stage: each Silver-studded Blue, for example (not a butterfly which you will find in your garden) only lives for 4-5 days.

This can be a great help in identification. If you see a blue butterfly in March or April it has to be a Holly Blue – none of the other blues are on the wing at this time. If you see a white butterfly in April, it is more likely to be a Green-veined White or an Orange Tip than a Large or Small White – the latter may be on the wing, but are much less numerous, judging from my experience in my garden. With the most common butterflies in the brown family, the Meadow Brown is out before the Gatekeeper – this year, the first Meadow Brown reported to the Dorset Branch of Butterfly Conservation’s website was 19 June, but the Gatekeeper didn’t turn up until 11 July. Most identification guides will show you the flight period of the adult, so use this information when you are trying to identify a butterfly you have seen.

Don’t forget size is important too – see my article on the subject. The Silver-studded Blue above is tiny, with a wingspan of about 30mm, wheras the Meadow Brown’s wingspan is around 50mm.

I’ve just had the first Meadow Browns in the garden; I haven’t got a photo of them yet, but the shot below is one of my favourite ones from several years ago.

A butterfly you can tempt to breed in your garden

9 May 2013

At last – the first Orange Tip! Although some other butterflies may be seen early in the year, the season really starts for me when the first Orange Tip arrives. I also had my first Holly Blue – it’s wonderful what a bit of sunshine will do.

The Orange Tip is a lovely little butterfly – and I mean little: it is smaller than the Small Tortoiseshell, Peacock etc., though bigger than some of the blues. The male has a very pronounced orange tip to the upper wing, but the female is all white on the top side. Both, however, are mottled underneath on their hind wings, as you can see in the phto below. The caterpillar is often found sitting along the tops of seedheads during the day.

There are several food plants for the Orange Tip caterpillar you can easily grow in your garden. A good wild flower is garlic mustard, or jack-by-the-hedge; this is a bienniel: i.e. it comes up one year and flowers the next, then dies. Mine are just starting to flower now, but by July or August it will have gone,  leaving room for later-flowering plants. The one thing I would say is that when you clear the dead plants away, they may have chrysalises on them (and you’ll never spot them) so if possible, tuck them out of the way somewhere and leave them there until next spring, rather than composting or binning them – the butterfly stays as a chrysalis all through the winter with the adult emerging in April/May. Garlic mustard will seed itself fairly copiously, but the plants are easy to pull up.

There is a second wild flower they use a lot: cuckoo flower (cardamine pratensis). This needs a fairly damp environment, and also goes back below ground early in the year. It is smaller than the other plants mentioned here: only 10-12″ high (25-30cm).

A good garden plant is Sweet Rocket (not the herb – you are looking for hesperis matronalis), which I’ve featured several times in this blog. It’s very pretty, the flowers lasting for weeks, and it usually survives 2-3 years. It is easy to grow from seed, but if you have got a plant of it, have a look at it in autumn, and you will often find some of the stems have flopped over, and where this has happened little plantlets have formed. Remove these plantlets and they will grow: if you can give them cover, your success rate will be very high, but even if you have to leave them outside, a little bit of cover will allow a good proportion to survive. I put some in the vegetable garden one year, put a cloche over them, and about half got through the winter. Pot up the rooted plantlets and you will have flowers the same year, though the plants will be bigger the following year.

Honesty: lunaria annua 'Coru Blue'

Honesty: lunaria annua ‘Coru Blue’

The other garden plant to try is honesty. I never had much luck with honesty until I discovered one called lunaria annua ‘Corfu Blue’. Despite the “annua” in the name, it is a short-lived perennial, and it is easy to take some of the seeds and germinate them in the autumn for the next year. Don’t be fooled by it being called blue – it is buer than most honesty, but not really blue – fortunately, it has lots of flowers to make up for it.

Most of these plants (I’m not sure about the honesty) are  known to also be food plants not only for the Orange Tip, but also for the Green-veined White, so if you don’t get one breeding on your plants, you might get the other. Try growing some and see…

Gardening for butterflies – adults v caterpillars

25 February 2013

When people say they want to attract more butterflies to their garden, they are nearly always talking about the adult stage of the insect – the one we see flying around in the sunshine (remember sunshine?). In a small garden, attracting the adults may be all you can sensibly aim at, providing them with nectar-rich flowers to give them energy to fly around and mate, which is very well worth doing.

It is good if you can, though, to also provide some plants which will serve as foodplants for caterpillars. I can hear you all groaning at the idea of having to have a garden full of nettles – quieten down! Nettles are good if you can accommodate them, but the butterflies are quite fussy about the nettles they use, which need to be in a sheltered, sunny position, so it’s not as easy as leaving a few behind the shed: do it if you can, but don’t worry about it if you can’t.

What you do have to do, though, is accept that the holes left in the leaves by the munching caterpillars will be visible – but what are a few holes when you’ve had the fun of watching the munching?

The most practical plants to grow to encourage butterflies to breed include:

Sweet rocket/honesty/lady’s smock for the Orange Tip and Green-veined White.  Sweet rocket is very easy, comes in white or purple, and lasts for 2-3 years. You could also grow garlic mustard,  a native wild flower which blooms early and has disappeared by the middle of summer – I’ve got some in the garden, and I can find caterpillars on it or my sweet rocket most years.

Holly and ivy for the Holly Blue, which uses both, at different times of year, for it’s egg-laying. You will struggle to see the egg or the caterpillar, though, so look out for the female flying around the bush.

Buckthorn for the Brimstone: this is a shrub and not very exciting to look at, but it does provide nectar in its flowers and berries for the birds, as well as leaves for the Brimstone butterfly, which is said to be able to find buckthorn from a considerable distance. There are two types of buckthorn, and you need to use the one which is good for your soil: purging buckthorn for chalky soils and alder buckthorn for acid soils.

British native grasses are also good – I’ll cover them in more detail in another post, as well as plants for moth caterpillars.

I’ll give the latin names of the flower plants I’ve mentioned here, in case you have difficulty identifying them by the common names, which tend to be different in different parts of the country: Sweet rocket – hesperis matronalis. Honesty – lunaria annua. Lady’s smock – cardamine pratensis. Garlic Mustard (also often called Jack-by-the-hedge) – Alliaria petiolata.
