Tremex columba

Tremex columba
Flatbush, Brooklyn, Brooklyn (Kings County) County, New York, USA
June 11, 2008
Size: 7/8 inch +
Found in and extricated from a shard of wood from a maple tree downed by wind. Previously observed exit holes where the trunk snapped, about 15 feet off the ground. The wood here was riddled with galleries, most packed with sawdust.

I believe this is a late-instar larva of a female Tremex columba, Pigeon Horntail. Specimen was still alive when this photo was taken. Full photo set is at http://www.flickr.com/photos/flatbushgardener/sets/72157605574734007/

Yes, sort of:-)
This is the PUPA stage of Tremex columba. Interesting find, and worth adding to the guide page.

Pupa vs. Instar
So it's not a little grubby guy. It looks like an adult, except for the tiny wings. At the far right is what looks like the remains of a pupal case.

But why were the wings not fully formed? That's what threw me off as to the stage.
