Common White Wave

This species has white wings, sometimes tinged with pink, with three dark fascia on the forewing and two on the hindwing. The wingspan is 32–35 mm. One or two broods are produced each year and the adults can be seen at any time from May to August [1]. This moth flies at night and is attracted to light.

The larva, usually purplish-brown with white spots, feeds on various trees and shrubs including alder, aspen, birch, oak, rowan and willow. The species overwinters as a pupa. From Wikipedia
