Horntails, Wood Wasps and SawfliesWhat is this?
We live in Eastern Canada and burn wood for the winter. This morning I caught this bug on the floor. What type of insect is this? and is it harmfull? Attached is a pic.

Hi Scott,
This is a non-stinging female Wood Wasp, Urocerus albicornis. BugGuide does not have much species specific information. The female wasp uses that threatening looking but harmless ovipositor to deposit her eggs in dead and dying wood. The larvae are wood borers. This adult wasp probably emerged from firewood.
