Fishing The Blue-winged Olive Dun:
Dun:
Baetis duns have two tails with a very tiny hind wing. Some species do not have a hind
wing at all, but this minor difference is not important at all and we point it out, just for
identification purposes. Like the name implies, the bodies of most duns are a green or
emerald - olive color with gray highlights and the wings are a shade of gray.
They can stay on the water a relatively long time if it is cold water and cold weather.
Presentation:
In some situations there may be lots of flies on the water making your dry fly imitation just
another one of many duns drying their wings in preparation to fly away. In this case, you
are much better off finding one feeding trout and concentrating on catching it, than
schools or pods of feeding trout. Everything relative to the emerger presentation applies
to the dun imitation, except it is fished dry on the surface. This is very demanding trout
fishing in many smooth water situations. Even in pocket water, the dun will float down the
current seams adjacent to the slow water areas where they hatch. Sometimes they are
trapped in shallow, calm areas within the pockets and calm areas of water along the
banks of the stream. In either case, this requires a longer and lighter than normal
leader.as well as a good presentation.
