The Small Blue Cupido minimus is the UK’s smallest resident butterfly. Females are chocolate brown whilst males, like the one pictured above photographed recently at Martin Down, have a silvery-blue dusting of scales near the base of the wings. The sole food plant is Kidney Vetch Anthyllis vulneraria and so it is reliant on the type of grassland habitat where this plant can flourish. It favours areas with broken ground.

The photo above of a second generation Adonis Blue Polyommatus bellargus taken at Martin Down in Hampshire shows the typical chequered fringe of the male. This is a butterfly which can only be confused with the male Common Blue Polyommatus icarus but in comparison that has a plain fringe as can be seen here. In my opinion the Adonis Blue is bluer, less purpley and the colour is rather more dense. I’ve found that the wings of the common blue are slightly translucent, so depending on the light, the spots and markings on the underwings can often just show through. You may just about be able to make this out depending on the quality of your monitor.
Adonis in Greek mythology, is the male god of beauty. This is certainly a handsome butterfly, arguably the most attractive of the British blues.

Last weekend I managed an early morning trip to Martin Down in Hampshire. In many ways it felt like the last day of summer. Certainly many of the butterflies, particularly the Dark Green Fritillaries and many of the Skippers were well past their best, distinctly tatty. But I usually find something interesting to gawp at and this time it was this wee beastie, the Giant Tachinid Fly Tachina grossa. Read more
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.
