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 recently deceased Trico was smaller and darker than the others I photographed from the same morning.
This mayfly was collected from the Neversink River in New York on September 8th, 2006 and added to Troutnut.com by Troutnut on October 4th, 2006.
