Fun facts
When it is scared, it plays dead. It folds up its legs and drops to the ground with its black belly up, so it is hard to see.
It can squeak by rubbing two parts of its body together. The sound may startle a hungry bird.
Its larvae cover themselves with their own sticky brown poo. It works like a shield against the sun and enemies.
One female can lay up to 450 eggs in a single season.
People sometimes mix it up with a ladybird without spots, but it is slimmer.
