General comments:
Extinct.

At the end of 2006 this was listed as an Endangered species in Hertfordshire (Plant, 2008). Now, it seems to have gone altogether. The decline appears, based on number of records, to have occurred throughout the 1980s and 1990s. There are only three records for the present millennium: Rickmansworth in 2001, Frithsden Beeches on 12th October 2002 and then Bricketwood on 17th October 2011. Prior to these, the last available was in 1993. Interestingly, the species may be more frequent at the present time in coastal localities of Britain, perhaps suggesting some common causes in the decline of this and the Garden Tiger Moth Arctia caja.
