Brown-tail moth

Euproctis chrysorrhoea

Brown-tail moth lavae Brown-tail moth nest

The larvae are dark brown and hairy with a series of white marks down the side and a characteristic pair of orangey-red ‘warts’ at the rear end.

They spend the winter months in tough webbing nests (above right) and emerge in spring to feed communally until about the end of May.

Although occasionally found on oaks, brown-tail moth larvae are much more common on hedgerow trees such as blackthorn and hawthorn or on scrubby plants, especially bramble.

The hairs of these larvae can provoke an allergic reaction, so contact with the larvae or their nests should be avoided.
