Erannis defoliaria

Mottled umber moth

Description

A mid-sized moth. The male is normally winged with a 40 mm wingspan. It is pale ochre to greyish yellow with two darker transverse stripes on forewings. The females are wingless. Moths are active in autumn (October and in November). The females do not fly, they crawl up the host trees and deposit eggs onto branches singly or in small groups in bark crevasses, under moss or in other sheltered places. The eggs overwinter and larvae hatch in spring. Sprouting leaves and buds are damaged by brownish green larvae. They perforate the leaves at first, later they feed on them leaving only the thickest veinlets. The pest can cause significant damage.
