Wood Wasp

Dear Cory,
This is one of the Horntails or Wood Wasps in the family Siricidae.  They have larvae that are wood borers.  Your particular Wood Wasp is Urocerus flavicornis, a species that uses conifers as the host.  According to BugGuide its range is:  “all forested regions of Canada and the US.”

  1. Is this the same as a banded horntail? I was camping in kananaskis in Alberta and saw a few big guys around my campfire! Scared me and my friend.

  2. 1. What is the normal size, of just the body as well as the body and appendage (stinger?) of the Wood Wasp as might be found in South Central Alaska, Anchorage area?

    2. Are the aggressive?
