A rather common species throughout Belgium.
The adults fly usually in one generation a year; from mid June till mid September. They come to light.
The larva lives in a silken gallery in several species of mosses like Isothecium alopecuroides and Hypnum cupressiforme which are growing on tree-trunks, rocks and stone walls. It hibernates as a small larva and pupates later amongst moss.
