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 captured this specimen in the same color as this photograph, during its egg-laying flight. The emergers are much lighter.
This caddisfly was collected from the West Branch of the Delaware River in New York on May 13th, 2007 and added to Troutnut.com by Troutnut on May 18th, 2007.
