"This means that the sirex wood wasp can also be classified as venomous," says von Reumont.

Sting was rather appropriately inspired by the humble female wood wasp, which uses a bendable, needle-like ovipositor to bore into wood and then lay her eggs.

"You would not know the design started off with a wood wasp - and that is a strength," says Prof Vincent.

It has a long and peculiar ovipositor with which it drills a hole into the tree and deposits the egg in a burrow of the Pigeon Horntail, a wood wasp that burrows into deciduous trees.

Probably he has found the larvæ which the wood wasp left there in the fall.
