I live in NW PA, and have no trout streams near my house, but there is a small stream about a mile away, where I have never seen a bug hatch from. I found a small, size 18-20,light brown(from what my friend said, I'm colorblind)mayfly with two tails. Wings were cloudy with no veination. The body seem rather stalky compared to what I'm used to. Any ideas? I know this is vague, and you bug guru's are gonna hate me.

Thanks, Mike. My first impression was that you had probably found a baetid ("two tails"), but I now think it might be a caenid that had lost one of its tails. These stocky little mayflies have broad forewings and no hindwings. Their wing and body shapes are similar to Tricos. The sparse venation (few cross-veins) would probably be fairly indistinct ("cloudy" wings). You might also have noticed a dark line along the leading edge of the forewing. Although it might have come from the stream you mention, it could also have come from a pond or lake. Does that sound right?

Yeah, Gonzo, sounds good. Also, there were no hindwings now that you mention it. But I really have no idea where is came from. The stream is the only body of water near my house. Thanks
