General comments
Extinct resident.

Foster (1937) states 'St. Albans, Bricket Wood (Gibbs)'. The species is not included in Gibbs (1889) list of the Lepidoptera of the St Alban district and so must, if correct have been made between 1889 and his death in 1917. Thus 1917 is the arbitrarily assigned year of our earliest county record, though it was undoubtedly before then. The only other record is that made by Goodson at Hemel Hempstead in 1945 (Foster, 1945a). The moth inhabits the edges of permanent bogs at inland sites and therefore, unexpected in Hertfordshire. The one and only Middlesex report is from Stanmore in 1970.
