Species Account

Sutton & Beaumont, 1989: Much less common than its congener A. monoglypha (Hufnagel) but still widely recorded and often common in all five vice-counties. This species particularly favours open situations, especially dry grassland as found on the Wolds, for example (PQW pers. comm.).

2012 (CHF): Common and widespread across the county. The biggest numbers are recorded in the Spurn area eg 99 on 25.7.1984 and it is less common on the upper ground than Dark Arches.
