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 ]
The family Thaumetopoeidae—the "processionary moths"—comprises about 100 species, of which three have been recorded in Great Britain: Oak processionary caterpillar. Thaumetopoea pityocampa, pine processionary — probably rare immigrant (otherwise imported) Thaumetopoea processionea, oak processionary — immigrant
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.
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 ...
Each volume has text, distribution maps, and illustrations of the moths it covers. When the series is complete, this will be the first time that all species of Lepidoptera recorded in Britain have been illustrated in a single reference work. Volume 7 part 2 contains a 241-page Life History chart covering all British species.
One of the biggest outbreaks of the Gypsy moth caterpillar took place in 1981, when the bugs made their way across the Northeastern states. As revealed in a New York Times report at the time, ...
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.
