Blue-winged Olives
Baetis

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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Jason can boot this if he wants, because it's kind of an advertisement, but I thought a few of the die-hard bug aficionados might be interested. I'm planning to give a workshop on western (north of Mexico) and far northern North American mayfly nymphs. It will be January 3-5, in Long Beach, California, USA. There is a price tag for participation (that I did not set). See the following link for more details, or send me a PM. This will be a fairly advanced and intensive event. I'll cover most topics at the species-level. Notably, a bunch of new regional and comprehensive identification keys will be debuted. This includes the first keys for several genera, greatly revised keys for others and the first discussions of some undescribed nymphs. Emphasis will be placed on the families Baetidae, Heptageniidae, Ephemerellidae, Leptophlebiidae and Leptohyphidae. Other contributors include Nick Wiersema (wrote keys) and Jeff Webb (wrote keys and will attend). Please feel free to share this information elsewhere, but please send me a PM first.

Ooh.... PM sent.

BTW - I think this kind of "advertisement" is fully Troutnut approved.:)
