Yorkshire Status: Scarce and local resident.

Sutton & Beaumont, 1989: The only fairly easily distinguishable member of the genus, at least if habitat and flight periods are considered. This moth is frequently recorded from higher moorland areas and occasionally from lower sites, presumably where heather occurs. S. P. Garland in 'The Moths of Sheffield' makes the interesting point that the flight period of this moth coincides with the grouse-shooting season when many moors may have very limited access, so it may well be under-recorded.

2012 (CHF): This species really ought to be much easier to identify than the other three Epirrita species. It flies in late August/early September (ie at least a month before the others), it is significantly smaller, and it favours upland areas. There are however difficulties. Large specimens occur with wing markings identical to Autumnal Moth and flight times overlap. To make it even harder, the genitalia are indistinguishable. Waring says an Epirrita moth in August on northern moorland is almost certain to be this species and he may be correct, but the situation is not as simple as it might seem!
