Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

My pictures really are not good, the cell phone just does not do justice. But if you look just up stream from the black water there are some really nice riffles, small caddis I believe anyways were hatching in the riffles and then floating into that black colored water. There were fish rising, and I fished a rather large size 14 caddis and caught close to 15 fish. One was a really nice rainbow, which rainbows are not unusual here, there mostly steelhead parr. I didn't want to do the fish picture thing because I didn't bring a net, the warm temps had me releasing fish as quick as possible with as little handling as possible. Anyway, I hope everyone here is doing good, I have had possibly the best year of fishing and yet I feel as though something is missing with all of the madness going around. Cooler temps next, I may hit the Ausable again, early morning tricos and then some terraistals later in the morning.
Take care and have some fun, Mike.
