Blue-winged Olives
Baetis

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.

Female Baetidae (Blue-Winged Olives) Mayfly Dun Pictures

This little gal is of the usual size for Baetid mayflies, around size 20. She came with two tails, but it's kind of hard to transport size 20 mayflies without a little bit of damage.

This mayfly was collected from unknown in New York on September 2nd, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
