Found this girl on my truck at 7A.M. This is, to my knowledge, Maccaffertium modestum. She is a Pittsburgh bug, from the Allegheny River. I've seen fish in the evening...warm water river fish...taking the Cahills from just under the surface...always before the duns are riding the surface. I've been trying to figure out these feeding fish, and I've had a couple on, but haven't landed any...yet.
