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 hatched in the middle of July, which is very late for this species.
This mayfly was collected from unknown in Wisconsin on July 14th, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
