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.

A couple years back we had someone post a video here of a mayfly hatching. I think it was from Europe and was E danica and they followed it closely as it progressed downstream with its shuck hanging off the back end...Does anyone remember it, and maybe how I can find it?
