Lepidoptera Tortrix Viridana Moth
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.
