General comments
Vagrant - with increasing frequency.

All reports of this moth must be backed, as a minimum, by a good sharp photograph or, ideally, by letting someone experienced see the actual moth. It is a very rare species that is turning up in Hertfordshire with increasing frequency - perhaps as a wanderer from Breckland.

Recorded in 14 (34%) of 41 10k Squares.
First Recorded in 1930.
Last Recorded in 2024.
