I have lumped the flies that I prefer for Australian Native fish into one group as by in large they are all structure oriented. they tend to frequent areas with structure such as weed, sunken logs, rock bars, under cut banks, holes and drop offs etc. and generally react in much the same way.
I tie a few hair winged duns but don’t tie them as representations of any particular Dun or Spinner (imago) stage of any specific insect. The Hair Winged Royal Coachman is an excellent example of a hair winged dun. It evolved from origins in England of the 1800’s.
If you have a look at Caenis Duns there are fundamentals of shape that are common across the species and captured by this pattern. The tail consists of only three filaments; the body starts thin and is then cigar shaped with 9 distinct segments. They have 6 legs and wings faces back at about a 60 degree angle. The common colours are grey and brown and when they are hatching the vision is of very small single winged sailing boats on the water.
