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 is a common species in states like Oregon and Washington but this is only the second time it has been collected in Montana.
This mayfly was collected from Bowman Creek in Montana on June 20th, 2007 and added to Troutnut.com by Bnewell on June 26th, 2011.
