Did you know pillbugs are not insects, but are crustaceans (related to crabs), and called isopods? They have a hard outer skeleton and jointed legs. They also have more than 3 pairs of legs (which is what insects have).
They are called pillbugs because their defense mechanism is to curl into a ball.
They aren't native to Australia but came out from Europe with the plants that were brought here by early settlers.
They feed on decaying organic matter.
