Species Account

Sutton & Beaumont, 1989: Quite common throughout all five vice-counties, especially in open grassland sites. This species appears to have been adversely affected by the weather of 1976 and at least in some areas became reduced in numbers for several years, although even then it was still reasonably frequent. The melanic form ab. combusta (Haworth) is common in VC64 and presumably elsewhere.

2012 (CHF): Common and widespread across the county, particularly in the uplands where large numbers are often reported eg 85 at Greenhow on 26.6.2011. The main flight time is May to July but late individuals are sometimes trapped in September and these are commonest in the uplands. In most areas the melanic ab combusta comprises 20 - 30% of the total.
