Posts: 8	Jason- This is actually a specimen of Acroneuria abnormis. Paragnetina species have a complete set of spinules/setae on the occiput, which this guy is lacking. On a semi-related subject, could you forward me the collection data for the Arcynopteryx paralella you got from the Catskills? Thanks a bunch.

"Bear Swamp," PA Posts: 876	Thanks, Peter. The ID mistake was mine, not Jason's. When he collected this specimen, I took a quick glance at it and assumed it was P. immarginata (which is the most common of the highly marked "golden stones" in the Poconos). When I returned to see his close-up pictures, I noticed the difference in the dorsal markings and realized I had made a hasty judgment.

Fairbanks, AK Posts: 1115	Thanks for the correction, Peter. I'll get you that Arcynopteryx info. Gonzo, I guess I can forgive you... ;) Really, thanks for showing me to that collecting spot! I got the first Cinygmula nymph I've collected, so it was worth it for that, among other things.

"Bear Swamp," PA Posts: 876	Jason, The forgiveness is appreciated, although it also means that we failed to collect a P. immarginata specimen for your site. But, the Cinygmula was a revelation to me as well. And I'm still trying to figure out why we found mature D. lata (cornuta) nymphs two weeks before they normally emerge in that stretch. That little stream was abnormally low and warm, but I'm not sure that accounts for the difference.
