Female Maccaffertium vicarium (March Brown) Mayfly Spinner Pictures

 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 on May 28th, 2005 and added to Troutnut.com on May 24th, 2006.
