Fun facts
When it is held or scared, it makes a noise like a squeaky running shoe or air hissing out of a bike tyre.
Nobody knows why, but it loves freshly painted buildings. Sometimes lots of them sit on the new paint.
The male's feelers are longer than its body, while the female's are shorter.
It lays its eggs in fallen trees, not living ones, so it does not hurt forests much.
