<a href="../20 --0016e6d77d7f97321204aefaa0e4 Content-Type: text/plain; charset=ISO-8859-1 I presume the name comes from the ovipositor and the accompanying sheath of the female. This particular one is *Urocerus cressoni*. (I am not aware of any common names for these, hence the scientific names. Apparently most people do not pay any attention to them). The larvae feed on conifers - spruce, fir and pine. Nathan Schiff's publication on North American siricids includes some superb photos about pp. 67-70. http://www.fs.fed.us/foresthealth/technology/pdfs/GuideSiricidWoodwasps.pdf On Mon, Oct 10, 2011 at 3:15 PM, James W.
