Hi there
I have been through your wood wasp shots but couldn’t find anything like this one. My parents found it beside their pile of firewood logs. It is about an inch long (2.5cm) and the ovipositor is a bit longer than the body. We have never seen anything like it. Some of the logs had 4mm bore holes in them.

Hi Peter,
Ichneumons are wasp relatives, but have their own page on our site. This looks very similar to our American Megarhyssa species, but we cannot conclusively say that is the correct genus without more research. Female oviposits deep in rotting wood where larvae feed on wood boring insects.
