The wingspan is 14–18 mm.^[1] It is a variable species. The forewings are mottled, often with some green or bluish-green visible. The antemedial line is black, strongly jagged and broadest at costa and is followed by pale greenish to white. The median area is pale to dark olive to olive brown. The postmedial line is black and often only visible as two sharp black teeth on the lower half. The postmedial area is mottled cream with brown to olive. The subterminal line is black and sometimes very distinct. The terminal line is usually reddish brown with a thin dark brown outer border. The fringe is pale greyish with dark brown at the anal angle, middle, and apex. The hindwings are chocolate brown, but slightly darker towards the outer margin with a thin dark brown border along the outer margin. The fringe is pale grey, but darker on the outside. The head and thorax are grey to greenish and the abdomen is brown.^[2]
