Red admiral Vanessa atalanta

The Red admiral on the right can be found in gardens, the countryside and even in cities, especially on ripe and rotting fruit in late summer and autumn. They are common in Europe, North America and the temperate regions of Asia.

In the U. K. the adults arrive each spring from southern Europe and lay their eggs singly on stinging nettle. In June the caterpillars hatch and feed inside a leafy tent held together with silk. A fully grown caterpillar is around 35 mm long.

The caterpillars pupate in July and August inside a leaf shelter and emerge in around 2 weeks. Some then fly south, others hibernate or die. Adult males and females are similar.

The adult on the top right landed on my jeans while I was walking my dog down a country lane. The one below and many others feasted themselves on my bumper crop of plums. While feeding they close their wings showing only the underside, which, like many of the other Nymphalids, is well camouflaged.

Boloria euphrosyne, the pearl-bordered fritillary

Boloria euphrosyne, peral-bordered fritillary

Above is the pearl-bordered fritillary, in the Nymphalidae family. The caterpillar hatches in May or June, feeds on violas, and hibernates in a dead leaf in July. When fully grown is up to 25 mm long. It has a black body with a row of white spots along each side. The spines on its back can be black, yellow or white. The head is black. It pupates the following May.

Adult wingspan is 38 - 46 mm, and it flies in May and June. The female is larger than the male, and often paler. There is usually one generation per year in Northern Europe and two in Central and Southern Europe. It is found in woodland clearings and edges. Formerly it was widespread in the UK, but is now uncommon.

Argynnis aglaja, the dark green fritillary

Argynnis aglaja, Dark green fritillary butterfly, adlut

Above is the dark green fritillary, Nymphalidae. It is found in moorlands, cliffs, sand dunes and open woods throughout Europe. There is one generation a year.

Eggs are yellowish laid singly on the stems of dog violet, and hatch in 2 - 3 weeks.

The caterpillar eats it egg shell then hibernates at the base of the plant. It emerges next spring and feeds until June or July. When not feeding it hides beneath the plant. The caterpillar is velvet-black with hairy spines, a yellow stripe along its back and red spots down both sides. When fully grown the caterpillar can reach 38 mm long.

The chrysalis is shiny black and brown and enclosed in a tent of leaves held together with silk.

The adult flies from June to August. It has a rapid and powerful flight. The adult wingspan is 48 - 60 mm, the females are usually larger than the males and paler in colour.

Painted lady, Cosmopolite, Cynthia cardui

Painted lady, Cynthia cardui, adult

The Painted lady, known in North America as Cosmopolite has a widespread distribution. The eggs are laid singly on the upper surface of the leaves of the food plants - thistles, mallows and nettles - in June and August, and hatch after about a week. The caterpillar spins leaves together to make a shelter to feed in, and reaches full size of around 28 mm long in a month. Pupation takes place inside the leaf shelter, and the adult butterfly emerges around 2 weeks later. Adults cannot survive the British winter.

Obrina olive wing, Nessaea obrinus
