Sutton & Beaumont, 1989: Locally common among birch but not recorded from VC65, although there seems to be no reason why it should not be present. Until recently this species was classified with the Cucullinae but it has now been moved in to the Amphipyrinae and the Dingy Shears, which it quite closely resembles, put into the same genus.
Argus 63, 2011:
VC65. Marne Barracks, 15.7.2011 (CHF, JCW, AJW). NEW VICE-COUNTY RECORD.
2012 (CHF): There have been increased numbers of records of this species in recent years though it remains local in the county, usually in small numbers. It is certainly less common than in Porritt's time when he described it as abundant in birch woodland at several sites. In some areas it can still be locally common for example at Potteric Carr where the peak count was 50 on 4.7.2011. The first (and rather overdue) record for VC65 was at Marne Barracks on 15.7.2011.
