I fished the MF Snoqualmie yesterday (Friday the 27th) and had a nice day catching small cuts. Caught them on top on caddis and an ant, caught more underneath on a PT. We moved to a new spot around 6:30 or so, and a large bug started hatching, swarming the air. They have a body color somewhere between cinnamon and brown, about 1/2" long, upright wings, and a long (1") forked tail. Can anyone tell me what this bug is? On a side note to this, the fish weren't coming to eat the adults or dead spinners, but I believe this is because two fisherman had just pounded the area pretty hard. I'm attaching photos (I hope). Thanks, all!
