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.

I hope that the attached photo shows up. It's of V Marinaro on the South Branch of the Au Sable in Michigan from the late 60's. Enjoy! I hope this works because I don't know what I'm doing here.
