The wingspan is 25–32 mm. The ground colour of the forewings may show whitish, grey, black or brown tints but the colour is extremely variable and there are strongly darkened forms. Prout[1] describes some aberrations.
Characteristic is the protruding post medial line on the front wings, which usually reaches the post discal wavy line or interrupts it. Very similar to Dysstroma truncata.[2]
Adult larvae are light green with two white dorsal lines. They have an approximately cylindrical shape as well as a blunt anus flap. The pupa is of green with whitish wing sheaths and has a brown, blunt rounded cremaster.
Adults are on wing from July to August.
It is found from Europe through the temperate zone of Asia through northwest China, Mongolia to the Russian Far East and Japan. It is absent in Portugal, on the Mediterranean islands and Greece. In the north, it occurs in Scandinavia up to Lapland and Iceland and the Faroe Islands. In North America it is found from Alaska and Newfoundland to New England and California. It is also reported in India.
It has been found at a height of about 2,400 metres in the Alps. It prefers mountainous areas, wetlands, mountain forests and bushy slopes.
