Common

Similar species: (These ID features are only useful for well marked specimens). Pale November Moth Epirrita christyi has the outer edge of the paler cross-band curving around the dark spot, but is almost in line with the edge of the band on each side. Small Autumnal Moth Epirrita filigrammaria is on average smaller (14 to 18mm) than the other three species and usually has a paler thorax. The outer edge of the paler cross-band is deeply indented away from the dark spot, but is almost in line with the edge of the band on each side. November Moth Epirrita dilutata has the spot in the paler cross-band either linked to the outer edge of the band or integrated with it. Autumnal Moth Epirrita autumnata has the outer edge of the paler cross-band forming a fairly deep indentation away from the dark spot which is well distanced away from the edge of the band on each side. If not totally sure, check the genitalia.
