Pine Processionary Moth (Thaumetopoea pityocampa)

OTHER NAMES: Pine Processionary
Latin Etymology: Thaumetopoea ("showing marvelous things") pityocampa (?)
Catepillars of Pine Processionary Moth (Thaumetopoea pityocampa at Mount Etna, Sicily, Italy - May 2018

Featured Subspecies: ?
Weight: ?  /  Length: ?  /  Wingspan: 31-49mm
UK STATUS NOT EVALUATED / IUCN Red List: Not Yet Evaluated 

An unusual instance where it is the caterpillar which is the far more notable and recognisable form of the species.  As adults they are small and unremarkable looking grey brown moths, but the larvae have a number of distinctive adaptations and behavioural patterns of note.  As they develop, they build a communal tent structure which they use as a base for foraging, including during Winter.  When it reaches time to pupate, they form long processions (as seen in the photo above) which are guided by pheremone trails.  It is here they are most directly of note to humans, as at this point in their life they also have allergy inducing hairs which can cause problems for humans and other animals
