Olive Dun Dry
Olive Dun dry is very effective on chalk streams and limestone rivers for Trout and Grayling.
The river olives, which this pattern imitates, are a hugely important species and an all season fly taken by Trout in all Trout waters. They are said to be very useful in bright conditions.
Olive Duns imitate a wide variety of flies and insects which inhabit the surface of the water. There is nothing like using dry flies and watching trout rise to the surface.
