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 left Chitina around 8pm after 12 hours dipnetting and 2 hours cleaning fish, then drove north toward home for 4 hours before stopping to "car camp" at the same Gulkana River access I photographed on my trip down. First, I took a few minutes to work on my nighttime river photography under the full moon.
