The Northern California Fly Fishing Board

The Hare's Ear is a great fly, though I agree with Trouttickler that the Bird's Nest is even better as a river nymph.

But on lakes...oooh boy! Try a Hare's ear with a black wingcase and the original flat gold tinsel rib, a very good Callibaetis nymph. I had one great windy afternoon on Manzanita Lake with the Hare's ear wet fly - I remember that Dave Hughes recommended it years ago as a Callibaetis nymph imitation. I greased it, and fish hammered it when twitched. Eventually lost both flies I had to premature rod raising - you know, a sharp tug and the feeling of loss....
