This species has not been seen in Belgium for a long time and is thought to be extinct.
The larvae feed on the food plant. It lives under the ground surface in a silken Gallery mining leaves from the underside. The mine resembles that of S. murinella. It seems possible that the ground should not be too mossy (as is often the case in places with Antennaria), but there must be sand as the larvae make sandy tubes on the ground.
The larvae feed on Antennaria dioica.
