Baetis

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 collected this mayfly on the same trip as a male of the same species. They are Maccaffertium vicarium mayflies of the type formerly known as Stenonema fuscom, the "Gray Fox."

This mayfly was collected from the Namekagon River in Wisconsin on May 28th, 2005 and added to Troutnut.com by Troutnut on May 24th, 2006.
