Pale Evening Duns - Spinners
The spinners have two tails that are about the same length as the body. Like most
spinners the wings are translucent or clear. The spinner fall usually occurs in the late
afternoon or evening over the same riffles the mayflies hatched in. The females touch
the surface of the water to deposit their eggs. When they are finished, they fall spent
on the water. Trout eat them when they are depositing their eggs and after they fall
spent. These spinners will collect in the current seams and end up in eddies and calm
pockets along the banks and behind boulders and rocks. They can also end up in the
heads of pools in the riffles and runs terminate there.
When they are depositing their eggs you want to present you spinner imitation where
you see this activity occurring. This may not be possible in some cases because they
may do so in the evenings.
It is best to fish to individual fish if you can spot them feeding on the spinners. If you
loose tract of the fly you may try moving it very slightly - just enough to see the wake
the fly makes. Just make sure you do this before the fly gets near the fish you are
trying to catch.
Present the spent spinner imitation below the riffles at the head of pools or runs. It is
very difficult at the normal late time of day to see the spinners or your spinner imitation.
You should concentrate on watching the leader at the point it connects to the end of
the fly line for any stops or changes in movement. The trout just sip the spinners and
make only a slight disturbance on the surface, so it is not easy to see them sipping in
the spent spinners.
