Scientific Name: Thaumetopoea pityocampa
English Name: Pine Processionary Moth
French Name: les Processionnaires du pin (='pine processionaries')
5 Key Characters:
Habitat: Pine trees and the ground nearby.
Flight Period: May-June-July.
Caterpillar: Live in nests from autumn to spring. Every evening unless very cold the caterpillars emerge in single file to feed on pine needles. They are a serious pest of pine forests. One day in late spring they form a single file procession behind one of the female caterpillars. They descend from the tree and the female leads them to a patch of ground where they will bury themselves in the earth to pupate. The caterpillars have extremely irritating hairs which hang in the air and fall from the nests long after the caterpillars have vacated. Neither the nests nor the caterpillars should be handled, and pet owners need to be on their guard in case animals are exposed to irritant hairs.
Host Plant: All types of conifers with Black Austrian Pine being the preferred host.
Status: Increasingly common.
Further Information:
The great French naturalist Jean-Henri Fabre wrote about this species. A translation into English of his observations can be read here. They are informative, detailed, charming and fascinating.
Photographed by Loire Valley Nature:
Photographs are numbered from left to right, top to bottom. 1 rash caused by the caterpillars hairs. This is a moderately sensitive person who came into contact with the hairs by picking up a cat which had been outside in the vicinity of caterpillar nests and had collected hairs off the ground or floating in the air in its fur. 2 - 5 a caterpillar procession near Chaumussay, April.
