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 one actually had a medium tan body when it emerged. By the time I took the picture it was dark as night. I was actually looking through my box of specimens trying to figure out where that tan one I caught disappeared to. Then I realized this is it.
This caddisfly was collected from the West Branch of the Delaware River in New York on May 15th, 2007 and added to Troutnut.com by Troutnut on May 18th, 2007.
