The Twin-spot Carpet is common throughout Great Britain, and the beginner is likely to meet with it in June and July during his first season. Our illustration represents the male, the fore wings of which are greyish brown, crossed by several dark lines, and with a double dark and conspicuous spot near the middle of the hind margin. The female is much lighter, and the markings are also lighter and less distinct.
The caterpillar is pale green, with a narrow whitish line along the spiracles. It feeds in April and May on the leaves of the wood anemone (Anemone nemorosa), chervil (Chærophyllum temulum), and other plants.
The Grass Rivulet (Emmelesia albulata)
We represent the genus Emmelesia by the Grass Rivulet—a pretty little moth that flies in June, and which is widely distributed though not abundant.
Its fore wings are pale grey, crossed by several white lines, the arrangement of which may be seen in our engraving. The hind wings are of the same ground colour, but have no markings except a white wavy line near the hind margin.
The caterpillar feeds during July and August on the seeds of the yellow rattle (Rhinanthus Crista-galli), protecting itself from its enemies by spinning together the petals of the flowers; and when full grown it changes to a chrysalis under the same cover.
The Netted Pug (Eupithecia venosata)
We now come to the enormous genus Eupithecia, containing about fifty small species, most of which are known as 'Pugs.'
