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 mayfly was collected from the Au Sable River (Mainstream) in Michigan on May 15th, 2010 and added to Troutnut.com by Entoman on March 3rd, 2012.
