Description

The wingspan is 14–18 mm.[2] 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.[3]

In Canada, adults have been recorded from mid-April to mid-May, in June and from July to September. In the UK, adults are on wing in July and August. Adults have been found visiting thistle flowers.

The larvae feed on red alder (Alnus rubra), grey alder (Alnus incana), paper birch (Betula papyrifera), balsam poplar (Populus balsamifera), willow (Salix species) and cherry (Prunus species). It is a solitary leafroller, found under a silken web on the upper surface of a leaf of the host plant. The frass is caught in the web.[2] Larvae have been recorded from mid-June to late July in North America.

Distribution

Found in northern North America and most of Europe, in Britain it is only known from only one site; Glen Affric, in the Highland region of Scotland.[2]
