The zebra pill bug is a woodlouse with black and white stripes, just like a zebra. When it gets scared, it rolls up into a hard little ball. It is a busy cleaner that turns old leaves back into food for the soil.

Fun facts

1

Its stripes may copy the pill millipede, which tastes nasty. So hungry animals leave the zebra pill bug alone too.

2

When it grows, it sheds its hard skin in two halves, first one and then the other.

3

The mum carries her eggs in a pouch under her belly. Up to a hundred babies can come out at once.

4

It breathes with little gill-like parts, so it needs damp places to live.

5

Pet keepers have bred zebra pill bugs with yellow stripes, white spots or almost all white backs.
