Very rare immigrant from mainland Europe: according to details on Atropos Migrant Moth totals, prior to 2019 there had been five confirmed records of immigrants, all from Kent (VC15): New Romney on 17 June 2003, Dungeness on 26 June 2011, Saltwood on 6 August 2014 & 1 July 2015, and Lydden on 1 July 2018. However in 2019 this total saw the unprecedented occurrence of four individuals (three in Kent, all on 24 July, and one in Hollesley, Suffolk, 24 June). Further Kent records in June 2020 (two) & July 2021 led to speculation of potential colonisation, although all records to date have been males and the likelihood of the sedentary female reaching our shores, at least under its own steam, is questionable.
Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 30-38 mm. Resembles Lunar Marbled Brown Drymonia ruficornis. Larva feeds on Aspen and Poplar.
