In June and July this pretty but destructive little insect may be seen flying in abundance in almost every oak wood. Its fore wings are one uniform pale green with the exception of a streak of yellow
along the costal margin; and, when at rest, scores may exist on a single twig without being seen unless closely examined. The hind wings are of a pale smoky tint, and rather glossy.
The larva is green, with black spots, and feeds in May and June on the oak and other trees, often almost completely devouring the foliage.
Peronea cristana
This moth is not so generally abundant, but is very common in many of the woods of the south. It is remarkable for the large number of varieties that have been observed, many of which have been regarded as distinct species.
Its fore wings are of some shade of brown or grey, with a light streak of variable colour along the inner margin, and a tuft of raised white scales in the middle of the wing.
It flies during August and September.
