A very rare and local species in Belgium.
The first generation larva lives on Armeria maritima and infrequently on Limonium vulgare in a silken tube in a seedhead feeding on the unripe seeds, the second generation occurs in dead dry seedheads.
Pupates in a slight cocoon in the seed heads.
The adults are active at sunrise and in the evening and later come to light.
The adults fly in two generations a year: from mid May to late June and again during July and August.
