An uncommon species in Belgium.
larva feeds within a seed capsule of Juncus
spp., and at the end of the
third instar, it constructs a case and feed externally on the seeds.
Most larvae overwinter full-fed, usually in leaflitter, less often
embedded among the seed capsules.
adults fly in June and July. They are active onwards from dusk till dawn at sunrise. They come to light.
