Species Account

Sutton & Beaumont, 1989: Fairly widely recorded and sometimes common in all five vice-counties. There seem to be certain inconsistencies in the distribution of this species, for instance it is recorded widely (though not very commonly) in VC61, where there is mostly quite low land, but in Wharfedale, VC64, it is apparently restricted to the moors.

2012 (CHF): Widely distributed across the county especially in VC63 where it is commoner than Red Twin-spot Carpet. Beware of the red-banded form which can look rather like Red Twin-spot Carpet, though this is an uncommon form in Yorkshire. Do not rely on the presence or absence of the notch on the inner edge of the medial fascia to separate these two species as this is not reliable.
