Distribution and Abundance: Local.

Primary Habitat: Woodland.

Flight Period: Single brooded in August and September.

Localities: Hackleton, Pitsford Water, Storefield Wood and Castor Hanglands.

Observations: The fortunes of this moth have roughly followed that of its larval food plant the elm. In the early 1970’s it was fairly common in light traps, by the end of the decade to my knowledge it was not being recorded anywhere in the county. This continued to be the case until the early 1990’s when a slow recovery in records began. Currently having regard to the amount of elm present it is possibly under recorded, but it has still not turned up in some suitable well worked habitats.

L.O.N.: 1907. Several localities. Common at sugar.

First Record: 1890, Edwards.
