Distribution and Abundance: Fairly common.

Primary Habitat: Woodland.

Flight Period: Single brooded in October and November.

Observations: Due to the moth’s similar appearance to the November Moth (E. dilutata), there has almost certainly been a confusion of records between the two species. The Autumnal Moth probably occurs wherever its foodplants alder or birch are well established. There are no records from the woodland Fineshade Rothamsted light trap in the eight years to 2000 although the moth occurs in the large area of birch less than half a mile away. This seems to suggest that the species does not wander extensively.

L.O.N.: Unrecorded.

First Record: 1882, Hull & Tomalin.
