Newly developed harlequin beetles escape the trees where they are born by chewing through the wood with large, strong mandibles.

Edit Hook


"This massive pair of mandibles belongs to a South American harlequin beetle, and is probably used only once in its life. The harlequin beetle larva lives inside a tree, where it feeds on the wood. Here it pupates, and when the beetle emerges, it has to chew its way to freedom." (Foy and Oxford Scientific Films 1982:161)
