The BWO Mayfly Emerger is a realistic pattern to fish during Mayfly hatches. Trout will focus on struggling mayflys more than the upright adults. The white wing collar BWO emerger imitates this struggling Blue Wing Olive nicely and sits just below the surface film while imitating a mayfly stuck in its shuck or newly hatched.

These beautifully hand-tied flies are available from Ames Fly Fishing in size 18 and 20.  Essential for all fly boxes!  Happy Fishing!
