Appearance
This species is unmistakable within its range, with bright yellow wings marked with small brown patches along the costa of the forewing and a small brown-edged white stigma, also on the forewing. The wingspan is 33-46 mm. The species has a complex ecology: sometimes one brood is produced each year but sometimes three broods are produced over a two-year period, with the result that adults can be seen on the wing at any time from April to October . This moth sometimes flies during the day but mainly at night and is attracted to light.The larva is brown or green with a "horn" on its back and feeds on a variety of trees and shrubs. Recorded food plants include apple, birch, blackthorn, currant, hawthorn, ''Prunus'', rowan, ''Amelanchier'' and willow. The species, due to its complex life cycle, overwinters either as a larva or a pupa.
