Operopthera brumata

Winter moth

Description

Winter moth together with mottled umber moth are the commonest loopers on oaks. About 2 cm long, pale green, hairless larvae damage leaves of oak and other broadleaves by perforating in spring. Later, they consume the whole leaves. They pupate in forest litter. The greyish brown moths (males) fly in late October and in November. They mate with females which have atrophied wings and are not able to fly. After mating, they move up into tree crowns where they lay eggs around buds. The egg overwinters. It is more common in wetter sites of oak stands.

Symptom

There are holes in the leaves of the trees, or they are eaten from the sides.
