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 is the first of it's family I've seen, collected from a tiny, fishless stream in the Cascades. The three species of this genus all live in the Northwest and are predators that primarily eat stonefly nymphs Merritt R.W., Cummins, K.W., and Berg, M.B. (2019).
On the way home from fishing the Golden Trout Wilderness, rather than going back the way we came (to Reno), we drove east to fly out of Las Vegas, providing an opportunity to see some new, really interesting country in Death Valley and the Ash Meadows National Wildlife Refuge.
Death Valley was geologically spectacular and ecologically fascinating, and Ash Meadows held Devil's Hole, a place famous in fish biology as the home of an entire species that evolved and remains in a single small (but very deep) hole in the ground, the Devil's Hope Pupfish. Because people are people (unfortunately), Devil's Hole can only be viewed from a cage, at a distance too far back to see any of the rare fish. It was still interesting to see. We got to see live pupfish, relatively close relatives of those in Devil's Hope, up close at a nearby springfed oasis, which held Ash Meadows Amargosa Pupfish.
This trip also gave me time to do everything I've ever wanted to do in Vegas itself, specifically 1) returning the rental car, and 2) flying home. That's the whole list.
On our way from the Reno area and the Upper Truckee to fish the Golden Trout Wilderness, we couldn't resist a detour to see the oldest (non-clonal) organisms in the world: the ancient Great Basin Bristlecone Pines and the Methuselah Grove. They did not disappoint.
