However it is from a different group, the sawflies and horntails. They have a broad waist rather than the narrow =E2=80=98wasp-waist=E2=80=99 that allows the wasp to twist and probe with t= heir abdomen. Horntails have larvae that feed in wood, usually very stressed or recently dead trees. This appears to be a Pigeon Horntail (_Tremex colmba_). Since most of their life is spent as a larva inside wood, we do not see horntails very often. This photo is a female. You can see the long, ovipositor (surrounded by a stiff sheath). You can also see the much shorter =E2=80=98horn=E2=80=99 at= the end of the abdomen in front of the ovipositor. Males have the horn, but lack the sheath and ovipositor. As always BugGuide has some good information: http://bugguide.net/node/view/36830/bgpage There is a thorough recent review of this group in the excellent Canadian Journal of Arthropod Identification: http://www.biology.ualberta.ca/bsc/ejournal/sgsbws_21/PDFs/sgsbws_21_intro.= pdf [Henri Goulet of the Canadian National Collection was a major contributor to this.] DBMcC Georges River, NS David McCorquodale Georges River, NS On Thu, Sep 11, 2014 at 11:14 PM, Burkhard Plache <burkhardplache@gmail.com= > wrote: > This insect was seen on Mt.
