Hellins states that eggs were laid in a row in a folded blade of grass about July 29, and that the caterpillars hatched out on August 12. According to Hawes, the caterpillar of this species does not hatch from the egg until the following spring. Although it does not seem to be very plentiful in fenlands, this butterfly certainly has a partiality for damp places, whether in the rides, or on the sides of woods, on hill slopes, or waste ground. Wherever there is a fairly large growth of the taller soft grasses that the caterpillars feed upon, there the butterfly may be found in July and August throughout the greater part of England and Wales. Reported from the Edinburgh district in Scotland; and in Ireland from Powerscourt and near Cork.

This butterfly is very like the Small Skipper, but may be separated from it, in both sexes, by the black under sides of the knobs of the antennæ. The black sexual mark in the male is finer, shorter, and much less oblique (Plate 125). The egg (Plate 124) is pale greenish-yellow, oval in shape, flattened above and below; the top is slightly depressed. The eggs are deposited in July or August, in dried grass seed-heads and inside the sheath of a leaf, and the caterpillars, according to Hawes, do not hatch until April. The caterpillar is green, with the incisions between the rings yellowish; there is a darker green stripe on the back, and the lines on the sides are yellow. The head is pale brown and striped with darker brown. It feeds from April to June on coarse grasses, such as _Triticum repens_. When full grown "it spins together the stems of the grass low down, with a network of white silk for pupation" (Hawes). The chrysalis is described as being long, yellowish-green in colour, and retaining the dark dorsal stripe seen in the caterpillar.
