They come in all of Europe, except in parts of the Iberian Halbindel, east to the Urals before. They live in Au and bog forests, marsh lands and Torfbänken and forest edges with many bushes.
Flight times and caterpillars
The Ivory lichens bear flies in one generation from May to mid-August. The young caterpillars occur from August in appearance, hibernate and can be observed in the following year in May.
Way of life
The caterpillars hatch in August. They overwinter and pupate in May in a slight web between lichens. They eat Erdflechten and liverworts. During the day the caterpillars hide in dry leaves or in the cracks of the bark of oak trees.
