Species Account

Sutton & Beaumont, 1989: A rather local species, mostly confined to the high ground in the north and west of the County.

2012 (CHF): There is much confusion separating this species and Lesser Treble-bar. Looking at the angle on the inner cross line is not easy as this feature varies. A better way is to look at the tip of the abdomen in the males (see Waring, Townsend and Lewington). Treble-bar is also usually significantly larger. It seems to be commonest in the north and west of the county. Both species are bivoltine in Yorkshire with the broods peaking in May/June and August.
