This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

I have fished South Mountains State Park in NC twice this month and the trout are eating a lot of something small. It's probably emergers of one or another but there are a lot of these small pale yellow flies that remind me of a fruit fly. I think they are micro caddis's but I'm not sure. I have grabed them and my best description would be pale yellow, 1 to 2 mm long (.04-.08"), a oblong stout body, with layed down caddis like wings on either side (same pale yellow color) that are twice as long as the body. when they fly they almost apear as small mayflies and fly slow. Any help would be greatly appreciated and especially any patterns to tie. The fish are feeding mainly on the surface but also under water as from time to time. Thank's
