It’s a Robin’s nest

5 May 2014

We’ve now had a sighting of the bird on the nest in our greenhouse, and it’s not a finch, it’s a robin. Our bird book said robin eggs were blue, which is what led to our confusion, but checking on the internet, they often seem to be brown. We’re just as pleased to have her! You can just see her in the photo, peering over the edge of the tray to see what I’m up to.

The eggs have just hatched, and we managed to get in while she was off the nest for a quick look – all four eggs have turned into baby birds and all four reacted to us by opening their beaks, so they seem healthy enough. They should fledge in about two weeks apparently – it seems so quick.

We’ve also had the first green-veined white in the garden, as you can see below – the green veind on the under-wings are clearly visible: these are not present if the butterfly is a Large or Small White. It is on the honesty called ‘Corfu Blue’ that I have mentioned before.

And just to finish off – a lovely clump of bugle (ajuga reptans) in full flower, which is attracting lots of bees. It is one of those plants that spreads quite rapidly if it finds the right spot, and makes for good ground cover – it can get a bit over-enthusiastic, but its dark leaves are so attractive, I forgive it. The white behind is a lovely perennial viola called ‘Ivory Queen’.

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.

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.
