Nashua, Hillsborough County, New Hampshire, USA
March 11, 2007
Size: about 17 mm
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
Moved from Winged Insects.

Dr. Dan Young (U. of Wisconsin) says:
"Yes, your image http://bugguide.net/node/view/98054 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.

Ha!
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

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