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.
A moderately rare mayfly perhaps because the nymphs are fragile that nymphs are usually damaged in collection making identification more difficult.
This mayfly was collected from Bowman Lake in Montana on July 12th, 2007 and added to Troutnut.com by Bnewell on June 26th, 2011.
