Dun Emerger. The Giant Dark Green Drakes start hatching very late in the day and
continue into the night. They usually hatch in the mid-summer. The emerging nymphs
swim to the surface where they shed their nymphal skin and hatch into duns. They drift in
the surface skim a short ways when they do this. The Perfect Fly Giant Dark Green
Drake Emerger has a trailing shuck that imitates the freshly emerged dun with the
nymphal skin still attached to the tail of the dun. It is a very effective fly if used at the right
time and that is, of course, during the hatch. Trout feed on the nymphs when they are at
this particular stage of the hatch.
Presentation:
The fly may be brought from the bottom to the surface on the swing or you may allow the
fly to dead drift just under the surface. An up and across presentation would be preferred
if there is much current. You may need to try a down and across presentation in slower
moving, or slick calm water. Remember, you will be fishing at dusk and into the evening. It
is best to get into a position that you can best see your drift. You want be able to see the
fly, but you can watch the tip end of the line for any change in movements indicating a
strike.
You can also try an up and across, on the swing, presentation, allowing the fly to come
back to the surface at the end of the downstream drift. You are attempting to imitate the
nymphs swimming to the surface to hatch. Stopping the rod tip at the end of the drift will
accomplish this if there is any current.
