Yorkshire Status: Abundant and widespread resident.

In 1907 Porritt said that this moth was "not generally common but of wide distribution". It has become considerably more common since then, and now can be found in good numbers all across the county. We normally receive over 2,000 records per year, and numbers now seem to be stable. A small second brood in August and September became regular after 2000 and has grown in size so that it is now almost as big as the first brood. This seems to have helped fuel the increased numbers seen after 2000. Counts of over 50 are common, the maximum being 143 in the Lower Derwent Valley on 19/8/2023. This species has the reputation of entering the ears of moth trappers standing near the light. Do let us know if this has happened to you! The only possible confusion species is Radford's Flame Shoulder which has not yet been seen in the county.
