Fly Fishing Yellowstone - Small Western Green Drakes (Flavs)

The nymphs of the Small Western Green Drakes swim to the surface of the
water to hatch into duns. The shuck splits open and the duns emerge in the
surface skim. During this time, they are easily eaten by trout. They are
completely helpless. These mayflies emerge for only an hour or so during clear,
bright days. Like many mayflies, the hatch tends to last much longer if it is a
cloudy or overcast day.

It is best to fish an imitation of the nymph up until you see the first dun come off
the water. At that time, I suggest you try either our "Perfect Fly" Emerger or our
Emerger with Trailing Shuck fly.  Both flies float with their CDC wing suspended
in the surface skim. The Emerger imitates the nymph when the dun first starts to
come out of the shuck. The Emerger with Trailing Shuck imitates the dun when
the nymphal shuck is still attached to its tail.

You can use an up and across presentation in the pocket water streams
allowing the fly to swing from the bottom to the surface. In smooth streams you
may use a down and across presentation again, allowing the fly to swing to the
