Similar species: 2450 Spectacle Abrostola tripartita.

Sutton & Beaumont, 1989: A very local species in Yorkshire but has been discovered from several new sites since the early 1970s. There has been some confusion over names in the genus, since this species was previously called A. triplasia, the name now given to the Spectacle.

2012 (CHF): Most records come from VC63 and 64 though it is often reported from some coastal sites. Away from here it is very local. Numbers may have fallen a little recently. Much less common than Spectacle everywhere.
