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.[1]

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.
