The Dark Green Drake duns usually show up very late in the day on cloudy overcast
days or otherwise, after dark. The Perfect Fly Dark Green Drake Dun is a very effective
fly. It is easier to see the take during the low light conditions using this large dry fly than it
is the emerger and you may very well end up catching more fish on the dun than the
emerger because of that.
Presentation:
You fish the Dark Green Drake Dun the same way as you fish a Great Olive – Winged
Dun. A down and across presentation to a feeding trout would be the idea situation, but
in low light or darkness, it may be best to simply cast to areas of the water that are best lit
so as to keep track of your fly. Remember, wading at night can be dangerous. If you are
unable to cast from the banks of the stream, you should wade into the area you intend to
fish before it is completely dark. Moving around in the calm type water these mayflies
hatch in will spook the trout. You want to avoid as much of it as possible. Don’t waste a lot
of blind cast and spook the trout. You are better off waiting for a trout to start feeding
within casting distance and then making your presentation.
You may want to consider one of the head lamps for tying on flies other close up
functions while you are fishing. These are almost used exclusively where the mayflies
exist in large quantities.
