Index of Subjects Hi Angus, Lance and others fly-bitten, Yes, this vaguely rang a bell. It seems that D. baumhaueri is an older synonym for the more recently preferred D. hyalipennis, according to a half-detailed paper trail which you might look at in the correspondence around a Bugguide picture of Dioctria, which site also has some pictures from Tom Murray: bugguide.net/node/view/13727 and also bugguide.net/node/view/13729 or just google to Bugguide.net -- you don't have to be a registered member to use it. Type Dioctria in the Search box to see about a dozen images, mostly males, but including a couple of females (your photo looks crisper). Bev Wigney (thanks Lance and sorry Bev, well at least one spelling alternative was correct) had a really nice pic but maybe she took it down - I haven't checked. Incidentally Angus, Bugguide has photos of a wide range of quality, some not so hot, but none of them exceeding the quality of those of yours that I've seen. You should really think of posting your collection of insect photos there as well at some point. The site has become a major resource for insect identification, and I've seen comments by taxonomists whose names I happened to recognize, who seem to trawl their specialities periodically. They are much more likely to do that there as they know about the site, but probably not likely to visit about someone's unknown personal site. So if you post your stuff there and can get it sorted into the correct family, sooner or later someone with experience trawling there may comment usefully on the ID of your unknown specimens. Cheers, Steve ****************************************** Quoting Angus MacLean <angusmcl@ns.sympatico.ca>: > Thanks very much, Steve. I couldn't find it on Bev's site.
