A very rare and local species in Belgium, hitherto only known from the Kempen and the south of the country. Rarely seen.
Native
The larva lives in a silken tube over the plants. Hibernates in the larval habitation and pupates in a subterranean cocoon amongst moss.
They are active in the sunshine and later come to light.
The adults fly in two generations a year, from late April to late August with most observations during June and August.
The larva lives on Thymus serpyllum, Rosmarinus and Salvia.
