There are certainly two broods of this butterfly in the season, and in favourable years there may be three broods. In an ordinary way the first flight is in May and June, and the second flight in July and August. The caterpillars feed on Poa annua, Dactylis glomerata, etc. Those hatched in autumn hibernate more or less completely, and become full grown in early or late spring according to the season. Sometimes, however, they seem to feed during the winter, and assume the chrysalis in March. Probably it is from such precocious caterpillars that the butterflies sometimes seen in April result.
The Speckled Wood, it was noted, prefers shady places; the present butterfly is more partial to sunshine and plenty of it. As its English name suggests, it is fond of basking on walls, but it does this also on dry hedge banks, sides of gravel pits, tree-trunks—in fact, wherever it can enjoy the full sunshine. It is not at all shy, and will be pretty sure to introduce itself to the notice of the collector as soon as he enters its domain. Although it now seems to be absent from certain districts in which it was once abundant, it may still be regarded as a generally common species in England and Wales, and even plentiful, in some years, in the southern, eastern, and western counties; it appears to be more local in North England. In Scotland it seems fairly distributed, and not scarce in the south; its range extends to Aberdeenshire. Kane states that it is everywhere abundant throughout Ireland. Abroad it is common throughout Europe, except the extreme north, and extends into North Africa, Asia Minor, and Armenia.
