Colias hyale, the pale clouded yellow, is a butterfly of the family Pieridae, that is, the yellows and whites, which is found in most of Europe and large parts of Asia. It is a migrant to the British Isles and Scandinavia. The adult wingspan is 52–62 millimetres (2.0–2.4 in).[1]
Description
The upperside of the male is more or less light lemon yellow, with the black marginal and submarginal bands more or less complete on both wings; the black middle spot of the forewing large, in centre of hindwing an orange-yellow double spot; base of wings more or less dusted with black. The underside is bright yellow, being somewhat lighter on the forewing, with small marginal and larger submarginal red-brown spots; the middle spot of the forewing black with pale centre, the hindwing bearing a double spot which is mother-of-pearl colour, encircled by a double ring of red brown; fringes above and beneath, as well as head and antenna red brown. In the female the ground colour of the upperside and the proximal area of the underside of the forewing is white, being slightly yellowish.
The egg is bottle shaped, whitish, with yellowish-brown stripes. The larva is bluish green or grass green, velvety, there being on the back two rows of blackish dots which are traversed by two thin yellow longitudinal lines, above the legs a yellow or reddish longitudinal side line, head dark green; the autumnal larvae without black dorsal spots. Pupa green, with yellow lateral lines.
Biology
The larva feeds on Vicia cracca, Fabaceae, Vicia, Coronilla, Medicago, Lotus, Cytisus and Trifolium.
Habitat
The species lives in flower meadows up to 2,000 metres above sea level.
Distribution
Recorded from Ireland only once in 1868 and has not been seen since. It is found in southern England and is common throughout the Palaeartic Region.[2]
