PLATE I.--FIG. 5 (female).
This specimen is the English Clouded Yellow. The wings measure from two
to two and a half inches across, the female being somewhat larger than
the male. Both sexes have the same broad black margin on the fore and
hind-wings, but the male differs from the female in having no irregular
yellow spots marked on these black borders, which are seen in the
female. The hind-wings of the female are of a somewhat darker shade
of yellow, tinged with green, than those of the male, and both sexes
have a bright orange spot about the middle of the wing. Beneath, both
sexes are alike, the fore-wings being of a lighter orange with several
irregular black spots and a margin of greenish yellow. The hind-wings
are of a uniform green colour with a red ringed spot about the centre
of each, accompanied by a silver-like dot in the middle. It is found in
quantities in most localities, from the coast to the pine forests, from
February to November. The caterpillar is green, with a stripe of yellow
and white, having several orange dots on it. It is a miscellaneous
feeder, preferring, however, leguminous plants.
