Swallowtail

European Swallowtail butterfly, Papilio machaon

Papilio machaon

I’m back from Cyprus now but while I was there this was one of the butterflies I was keen to photograph, the  European Swallowtail Papilio machaon. This is the subspecies syriacus. I was lucky enough to get this shot early one morning while walking along the cliffs of Kapparis. The colour of the grass in the background will give you some idea of how hot it was.

We get them here in England and I’ve previously written about them in a post about one I photographed in Kefalonia here but our native subspecies britannicus remains a rarity and is confined to the fens of east Norfolk.

However, in some years we do get a few migrants from the continent. This subspecies gorganus is less fussy and will use many kinds of Umbellifer, such as Wild Carrot daucus carota, as the larval food plant. In 2013 there were many sightings in Hampshire, Sussex and Kent including some evidence of egg-laying. In April 2014 a specimen was photographed near Winchester, Hampshire which suggests that some specimens may have successfully over-wintered. More info here.

So the continental species may well become more common in future.

The Clouded Yellow

The Clouded Yellow Colias croceus isn’t a butterfly most of us get to see every year. It’s a summer migrant from southern Europe. If you live near the coast in Devon or Dorset and you’re the type of person that looks then you might get to see one or two each year. But further north you can go for years without seeing one at all. In nine out of ten years it is scarce. Then for reasons that we don’t fully understand we get an invasion. A glorious ‘Clouded Yellow year’ where numbers can be exceptional and individuals can be seen throughout the country and if we are truly blessed as far as southern Scotland.

Sadly the year after, again for reasons we don’t fully understand, numbers can be extremely poor.

So having spotted a dozen or so on Saturday afternoon at Martin Down NNR in Hampshire, I did the only sensible thing and went back again on Sunday morning. Well, that and the fact that my photos from Saturday were truly shocking. In my defence they’re tricky to photograph in as much as when they land they immediately fold their wings, plus they are all too easily spooked.

As you can see the underside is attractive enough but you really need to get out there and see them flying to see the upperside which is rather stunning – something not lost on the Victorian collectors. Both upper wings are a warm sulphur yellow with black margins. The upper with a single black eye-spot, the lower with a double dark orange, yellow-edged eye-spot. For a change the female has the edge in colouration in that the black margin is sprinkled with bright yellow dots. These are absent in the male. The French have a good name for this butterfly ‘Le Souci’ (The Marigold) which is very descriptive of the upper wing colour.

I saw plenty of Clouded Yellows in Cyprus earlier in the year so it was great to see them here in good old blighty.
