2026 Orgyia antiqua (Vapourer) L

Erebidae, Lymantriinae Final Length: ~30mm.

This small Lymantrid is quite local in Cornwall, although fairly common where they occur, as eggs are laid in large batches on the cocoons. The only means of dispersal is by the fast moving caterpillars spreading out from their hatching area. The bright colours of the caterpillars indicate that the hairs are urticating, and these are even transferred to the cocoons when spun. Even moving the cocoons resut in bad irritation to skin.
