The adults can be found feeding on flowers along woodland rides and hedgerows during the summer. The right conditions having been found and an egg discharged through the boring instrument, from this in due course issues a six-legged, whitish larva, which sets to work with capable jaws on the solid wood, beginning the excavation of a long tunnel that will occupy several years before the larva is full-grown. Each wasp species has its own characteristic body markings which you can spot only up close.

In some instances, these processes can occur within a couple of years. The species has reached other continents, such as Australia, South Africa and North America, through the export of timber and firewood. Holes that penetrate into the wood are also signs of wood borer larvae. This is a very large (up to 4 cm long) sawfly with a distinctive yellow and black banded abdomen. Through wood export, the wasp could spread to East Asia, West Australia and parts of Africa. A very large and impressive insect which resembles a wasp or hornet, but is completely harmless.
