The egg is pale green when first laid, and in shape it is almost
spherical, but rather higher than broad; it is finely ribbed and
reticulated, but unless examined through a lens it appears to be quite
smooth.
The caterpillar when full grown is whitish-green, dotted with white.
From the larger of these dots on the back arise greyish bristles; the
three lines on the back (dorsal and subdorsal) are whitish, edged with
dark green; the line on the sides (spiracular) is white, fringed with
greyish hairs; anal points green, hairy, extreme tips white. Head larger
than the first ring (1st thoracic segment), green dotted with white and
hairy, jaws marked with brownish. It feeds on grasses.
The chrysalis is green, with yellow-tinted white markings on the edge of
the wing covers and ridges; the spots on the body are yellowish, or
sometimes white. Occasionally the chrysalids are blackish, with white or
yellow points on the body.
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.
