Fun facts
A brand new grown-up beetle is creamy white. It slowly gets darker until it is bronze-black.
Its babies spend the winter inside rotting logs.
To survive the cold, the babies make their own antifreeze, a bit like some fish in icy water. It keeps them alive down to about minus 11 degrees.
It stays in its resting stage, the pupa, for only 10 to 14 days before it becomes a beetle.
