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.

Male Cinygmula par Mayfly Spinner Pictures

This spinner came from one of those huge swarms that make one just stop fishing and admire the spectacle. Not bad for a little-known species.

In the same swarm I collected a female and another male.

This mayfly was collected from Mystery Creek #249 in Washington on July 4th, 2020 and added to Troutnut.com by Troutnut on July 12th, 2020.
