Binomial name
Agriopis marginaria (Fabricius, 1776)

The female of this species has only vestigial wings and is totally flightless. It is usually found resting on the trunks and branches of the larval food plants. The male has orange-brown forewings with a paler yellowish band and a row of dots along the termen which gives it its common name. The hindwings are whitish with faint fascia. Melanic forms are frequently seen. The wingspan is 36–42 mm. The adults are active from February to April, the male sometimes coming to light but not strongly attracted.

The larva is greenish-brown with dark cross-shaped markings along the back and feeds on a range of trees and shrubs (see list below). The species overwinters as a pupa.
