A very local and very rare species in Belgium, hitherto only known from the coast.
The adults fly in July and August in one generation a year. They are active at dusk and later come to light.
The larva feeds on Salsola kali and very rarely on Atriplex. At first, it burrows into the stems, usually the side-shoots and later it feeds externally under a silken web on the unripe seeds. Hibernates as a pupa in a subterranean cocoon of silk mixed with sand, it may lie over two years.
