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.
I only took two partial pictures of this specimen to test out one of my microscopes.
This mayfly was collected from Fall Creek in New York on November 15th, 2004 and added to Troutnut.com by Troutnut on April 12th, 2006.
