Bionomics
The larva bores into a seed pod of Ulex europaeus or Genista spp. and feeds on the developing seeds. Later it leaves the pod and constructs a cigar-shaped case made of sepals. Finally, it leaves its feeding case and spins another case entirely made of silk.
The larva pupates after overwintering.
The adults are day-active, especially at dusk and later on come infrequently to light.
Flight periods
The adults fly from late May till early July in one generation.
