General comments:
Vagrant / immigrant.

Recorded once from Roughdown Common at Hemel Hempstead (Herts) on 7 September 2016, from Harefield (Middlesex) on 24th July 2022 and at the nearby Maple Lodge NR (Herts) a few days later on 29th July 2022. This is a primary immigrant that has started to visit Britain with increasing frequency. In many cases, examination of male genitalia may prove desirable to prove a record (males have feathery antennae rendering their selection easy).

	Retained Specimen / Photograph will be Required.
