Identification Tip

These large, white and grey moths are furry with marbled wings.

What do they eat?

Caterpillars munch on:

  • Poplar and willow trees, especially young trees in sunny places

Adult Puss moths don’t feed at all, instead they survive on energy stored in their body when they were caterpillars.

Where does it spend the winter?

These moths make a very tough cocoon out of chewed bark and silk, on posts or tree trunks. They stay in their cocoons, as chrysalises, all through the winter and occasionally through two winters.

Fun Facts
about the Puss Moth

The caterpillars of Puss moths are very striking to look at, with large green bodies, two pink ‘tails’ and red collars around their head. When threatened, they can squirt acid from a gland just under their head.
