(Linnaeus, 1758) 2022 / 71.001

Norfolk status
Former rare immigrant/adventive, much more common in recent years.

First Norfolk record in 1995 at Sea Palling (Alec Kolaj) the 8th record for Britain at the time.

Several adult moths recorded in Norfolk in recent years. So far, no larvae have been seen.

In Europe it is a pest species, the larvae feeding in large numbers on Oak.
Contact with the hairs of the larvae can cause severe (occasionally life-threatening) symptoms.

Similar to Pale Eggar, but shows small crescent mark in the centre of the forewing.
