Range & Status
Not listed by Parsons (1993) because it is found only in artificial or synanthropic conditions, but listed by Ball (1986) as notable. Goater (1986) notes that it is rarer than formerly. There are only two published recent records in Britain, in Cornwall (Spalding, 1991a) and in Essex (Harley, 1992), both records of adults to light. We consider that this species should be given RDB status.
Recorded in Cornwall once only on a farmyard near Truro (1990) and may not still be
