Classification

Family:Notodontidae
Subfamily:Thaumetopoeinae
Genus:Thaumetopoea
Species:processionea
Authority:(Linnaeus, 1758)

Rare immigrant from mainland Europe, appearing in southern England. It is expanding its range on the continent and is resident on the Channel Islands, and likely to be reported with increased frequency. While the Moths of Hampshire and Isle of Wight (Goater & Norriss, 2001) states "15 or so records of this species (all males), since the first in 1983" this account must be erroneous as the relevant atlas map shows no dots for the county and there are no reports on the county database from mainland Hampshire before two on consecutive days in mid-2004. On the Isle of Wight, reported for the first time in September 1998. The year 2020 saw a considerable increase in numbers and expansion of range, particularly into the north-east of Hampshire and Isle of Wight, with at least 26 individuals being reported. Wingspan male 31-35 mm, female 36-41 mm. Similar to Pine Processionary T. pityocampa, but has smaller and weaker comma-shaped marking in the centre of the forewing. Larva feeds on Sessile Oak, Pedunculate Oak, Turkey Oak and Evergreen Oak, living gregariously within a silken web.
