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 uncooperative specimen as part of a small cloud of female spinners clustered tightly together high about 10 feet above the water, without any males that I could see.
This mayfly was collected from the Namekagon River in Wisconsin on June 21st, 2005 and added to Troutnut.com by Troutnut on May 26th, 2006.
