This is a Giant Root Borer. The kids found it on our front porch. Here is a better picture from a bug guide. The one on the porch was about 2" long. Just enough to make me realize that even though this guy is not dangerous, my imagination does all the work and he is lethal!
And yes, we collected the specimen, and identified him using a field guide. We are a home school family, of course!
Now I did make sure that the lid was secure on the jar...just in case!
