A very rare and local species in Belgium. Probably underrecorded due to the similarity with other species of the genus, especially with Bryotropha basaltinella.
Distribution after 2004 is based only on specimens checked for genitalia.
The larva feeds on moss growing on walls, living in a silken gallery.
Pupates in an open network cocoon inside the larval habitation.
The adults are nocturnal and come to light.
The adults fly from late May till late August.
