| "Bear Swamp," PA Posts: 866 | Sorry, Jason--hasty judgement. This specimen appears to have a setal row across the occiput. Probably Paragnetina media. I'm not used to seeing a distinct "W" on the head of media, so this one threw me. But, I can't think what else it could be. (Way too dark for immarginata, and the abdomen would be patterned.) | |

| Posts: 6 | This may in fact be media, but Gonzo is right, the markings are usually not this distinct (especially the 'w'). To me, this looks more like a darkly colored immarginata. Differences of habitat frequently cause variations in color, and it is tough to distinguish for sure, based on the photos. Immarginata has transverse banding on the abdominal terga, and this specimine has an especially dark abdomen, making it hard to tell. Also, just to point out, Gonzo, the occipital ridge is not made up of setae. It is a closely set transverse row of spinules. And to the other comment, a golden nymph will work fine for fishing, as it's still a perlid. Besides, I don't think trout can ID to species... | |
