B&F: 1913

ABH: 70.234

Status: Resident.

Distribution and Abundance: Common.

Primary Habitat: General occurrence.

Flight Period: Single brooded in August and September.

Observations: This moth has the most extended emergence period of any of the autumn flying thorns, sometimes appearing as early as the third week in July with stragglers still on the wing in early October. It seems to prefer woodland edges and was particularly common at light along the edge of Glendon Wood in 1983. In the decade to 2009 the static Pitsford Water light traps show considerable variation in the number of moths captured. The average catch was fifty-nine with a low of fourteen and a high of one hundred and thirty-two.

L.O.N.: 1907. Many localities. Rather common.

First Record: 1882, Hull & Tomalin.
