A rare species in Belgium. As with other Psychids, this species is probably underrecorded.
The rather small case is attached to bark in such a way that it simulates exactly a bud and thereby making detection very difficult. The larva hibernates in the case and pupates in it.
The moths are mainly active in the morning sunshine. They are also active at night and sometimes come to light. The female is apterous.
One generation a year: May–July.
Forests, gardens, parks.
