A Wood Wasp, also known as a "parasitic wood wasp" or "horntail", is a mostly harmless flying insect, about 23 mm long, common for example in the United Kingdom. They are named for their habit of feeding on dead wood. The female has a tube at the back of her body which gives her a dangerous look, but it is an ovipositor. Families See text. ...

A description with photo (http://www.uksafari.com/woodwasp.htm).
Apparently these wasps only lay eggs on trees that still have their bark on them, and this is a key to the relative importance of these wasps in structures.
Their presence in the wood of a structure always is the result of their being built in with wood that was already infested.
I witnessed this one time in a year when the woodwasp population seemed to be at an all-time high, and a lot of people were experiencing encounters with the wasps.
