Features
The moths reach a wingspan of 10-13 millimeters. The head is whitish tinged with pale brownish yellow and strong. The thorax is light brown. The forewings are dark mottled gray-brown and whitish. An obliquely inwardly facing white band located at 3 /4 of the forewing length. This binding is often constricted in the middle, both sides are light brown bands. The inner band is larger and more irregular. Small tufts protruding slightly brownish scales are located at 1/ 4, 1/ 2 and 3/4 on the wing inner edge. The base of the forewing inner margin is ocher, the first half of the forewing inner edge is white. The hind wings shining gray. In females, the white band is broader and the eighth abdominal segment is ventrally gray brown.
In the males, the cucullus is slender, slightly curved and has a rounded and slightly broadened peak. The saccule tapers to a long apical appendage. He is only slightly curved, blunt ends and extends beyond the cucullus addition. The Anellus lobes are small and club-shaped. The aedeagus has three equal Cornuti. The left is strong, hook-shaped and fitted with tiny needles. The mean is bifurcated. The right is slim, tapers to distally and has a small hook.
In females, the eighth tergite twice as wide as long. The rear section is not sclerotized and U-shaped. The sinus vaginalis is funnel-shaped and as wide or slightly wider than the dilated part of the ductus bursae. The first part of the ductus seminalis is small and oval and opens into the back part of the ductus bursae.

Biology
The caterpillars develop on various willowherb species such as mountain willow herb (Epilobium montanum ), Marsh Willowherb (Epilobium palustre ), Lancet fireweed (Epilobium lanceolatum ) and Kleinblütigem fireweed (Epilobium parviflorum ). In Finland you can find the caterpillars also to the originally native to North America glandular willowherb (Epilobium Adenocaulon ). Evidence of Epilobium alpinum and Chamaenerion angustifolium be doubted, and require confirmation. The caterpillars live from June to July in the stem near the leaf base. As a result of feeding activity occurs on the stem at the base of the petioles a plant gall. Above the bile plants often leads to high branches. The caterpillars pupate inside the gall in a white cocoon. The moths emerge in August, winter, and can be found in May in the following year. On warm winter days, you can find the moths even in December and January.
