The oak processionary (OPM) (Thaumetopoea processionea) is a moth whose caterpillars can be found in oak forests, where they feed on oak leaves, causing significant damage. They travel in nose-to-tail processions (hence their name), often arrow-headed, with a leader followed by rows of several caterpillars abreast. [ 1 ]
Thaumetopoea is a genus of moths belonging to the family Notodontidae. It was first described by Jacob Hübner in 1820. In their caterpillar form, they bear the vernacular name of processionary because their gregarious larvae conspicuously move in single file. The adults live a few days without feeding.
Thaumetopoein is a urticating protein found in the hairs and integument of the caterpillars of the pine processionary (Thaumetopoea pityocampa) and oak processionary (Thaumetopoea processionea). [1] It was first identified in 1986 by a group of French scientists at the University of Bordeaux.

Lepidopterism is an irritant contact dermatitis caused by irritating caterpillar or moth hairs coming into contact with the skin or mucosa. [1] [2] When referring to the cause, moth dermatitis and caterpillar dermatitis are commonly used; Caripito itch (known as papillonite in French) [3] [4] is an older name referring to the moth dermatitis caused by some Hylesia species.
The larval stage of some Thaumetopoeinae are known as processionary caterpillars, so named because they move in columns in search of food, resembling a procession. [5] Some of the species, like the pine and oak processionaries, can constitute a health hazard due to their urticating hairs. Caterpillars of the pine processionary (Thaumetopoea ...
