What is a Brown Tail Moth?

The brown-tail moth, or Euproctis chrysorrhoea, is a member of the family Erebidae and is commonly known by its scientific name. It is endemic to the northern coasts of Europe, Asia, and Africa.

Moths have an unusual life cycle in which they spend almost nine months as larvae (caterpillars), from August to April. This leaves about one month for pupae, imagos, and eggs.

Caterpillars (larvae) have hairs all over their bodies. These species of hairy moth larvae can be distinguished from others by the presence of two red spots on their backs near the tail.

Adults with wings are white all over except for a tuft of brown hair on the tip of the abdomen. Typically, females will deposit their eggs in a cluster on the underside of a leaf of their host plant.

This species eats a wide variety of plants, including pears, apples, maples, and oaks, thanks to its polyphagous diet. Their caterpillars are voracious eaters that will defoliate broadleaf plants eventually causing the plant to die.
