(Linnaeus, 1758) 2020 / 73.033

General comments:
Declining resident - extremely local and scarce.

National populations have suffered a 95 per cent decline since 1970. This seems to be reflected in Hertfordshire and Middlesex, where it has vanished from most places where it was once numerous. The larvae are distinctive and easily beaten from the foodplant - they should be searched for (and reported!).

Retained Specimen / Photograph will be Required.

Recorded in 23 (56%) of 41 10k Squares.
First Recorded in 1887.
Last Recorded in 2023.
