November and Winter Moths Epirrita spp./Operophtera brumata

The November Moth, Epirrita dilutata, is similar to the Winter Moth but larger. It is hard to distinguish from the related Pale November and Autumnal Moths, also Epirrita species which fly in the same autumn months. If a small black spot in the centre of the forewing is visible and the strong forewing vein goes through the spot rather than beside it, it is November Moth. Shown are melanistic forms.

Wingspan 38-44mm; flight Sep-Nov. The underside view is only playing dead - the moth righted itself shortly after and flew away. All above photos taken in November (different years).

These photos of November Moths, one with the Winter Gnat (also called Winter Crane Fly) were taken in mid December by Martin Starnes.

These are thought to be the Winter Moths, Operophtera brumata, a melanistic and a normal form. The male is a hardy chap who survives freezing December/January nights. (Photos taken in January and December respectively.) Wingspan 22-28mm. The female is virtually wingless and stays on trees. It is similar to the Northern Winter Moth.
