(Linnaeus, 1758) 2137 / 73.350

Norfolk status
Immigrant.
(Resident in the Scottish Highlands)

The resident Scottish populations are usually very dark, while the immigrants are much paler and greyer.

Most Norfolk records occur in August and September, with the adults coming to sugar and light.

The larvae feed mainly on Bog Myrtle, but also other plants and bushes, such as Sallow and Birch.

In mid June 2010 two larvae were found feeding on scrub Birch in the Norfolk Brecks, (Chris Jones, 16/06/10), they pupated on the 17th June, with adults emerging on the 19th and 20th July 2010. The adults were of the pale grey form associated with immigrant specimens. Unfortunately no specimens were retained for confirmation.
The discovery suggests that in 2010, at least temporarily, there was a breeding population in the Brecks.
