Synonymy

Biology

Very little is known about its ecology. The larva is unknown but may be a stem or root borer as most other members of the genus adopt this larval feeding strategy. The known locality in Great Britain is Machair grassland but, it has also been found on limestone grassland and adjacent sand dune systems in western Ireland.

Status

VULNERABLE - Ball & Morris, 20143.
