Found this in same drowned deciduous tree as a bunch of new-to-me teneb*rionid larvae and a weird-looking Pityo*bius clic*k beetle larva. I'm hoping all will mature so they can be further IDed and photographed. I also found some uropo*did mit*es that I have yet to process and post.

This larval was quite plump and showed very little motion. I suspected (wrongly, see below comment) that it was either parasitized or ready to pupate. My closest guess was beet*le family Bostrich*idae.

Moved from Winged Insects.

Dr. Dan Young (U. of Wisconsin) says:
"Yes, your image is a symphytan Hymenoptera - most likely Siricidae."

I might add that this larva is no longer nearly motionless but is now very active. If horntails enter diapause, I think that's what was happening with the larva. A few days of indoor temperatures brought it back to life.

Moved from Beetles.

Looks like I'd better move this down the taxonomic tree for now. Hopefully it will mature.

That´s what I instantly thought, too
another possibility is Xiphydriidae - they look similar. I also share Jims assumption about the reasons of plump shape.

cheers, Boris

This looks like a larva of the family Siricidae (Hymenoptera: 'Symphyta'). I could be wrong, though.
