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 nymph is missing a few gills, but is otherwise in good shape. It was the only one of its species which turned up in my sample.
This mayfly was collected from Paradise Creek in Pennsylvania on May 29th, 2007 and added to Troutnut.com by Troutnut on June 4th, 2007.
