Yorkshire Status: Common and widespread resident.

Porritt in 1907 said this species occurred "all over the county and in many places plentifully". This is still the case, but it is much less common than some of the other "Yellow Underwings" and is trapped in much smaller numbers. Unlike Large Yellow Underwing where catches are frequently into three figures, there are only a handful of counts of over 30 moths, and almost 90% of records are of just one or two moths. It is widespread across the county, so it is odd to see the comments below in Sutton and Beaumont reflecting on its scarcity in VC65 at the time. This probably reflected a lack of recording in the VC. It is more of a woodland moth than some of the genus. The August "dip" in the flight-time phenogram is probably to to aestivation; a habit it shares with several others of the genus.

Sutton & Beaumont, 1989: Recorded fairly sparsely from vice-counties 61 to 64 but seems to be present at a low density in most wooded areas. However most records are from light traps so its frequency as a larva cannot be commented on. Map 110 in MBGBI 9 shows a VC65 record but this has not yet been traced, however since Dunn and Parrack (1986) state that it has not been taken in any western traps in Durham, it could be genuinely rare or absent from much of the vice-county.

Recorded in 159 (80%) of 200 10k Squares.
