What’s this bug?
A friend of mine photographed this bug on her deck and was wanting to know what kind of bug it was. I looked on your site, but couldn’t figure it out. It was photographed in Woodbury, St. Paul, Minnesota.

Hi David,
You can find images and information on the Pigeon Horntail on our Sawfly page. Pigeon Horntails are non-stinging wood wasps whose larvae bore into wood. Those larvae provide the primary food for the larvae of another non-stinging wasp relative, the Giant Ichneumon.
