CDC Mayfly Dun
Many people are timid when it comes to using CDC as a fly tying
material. CDC is one of the easiest materials to use in any fly and the
results are super. You never have to add floatant to a fly tied with CDC
and it floats like a cork. This pattern is simple, easy to tie and it
works especially well during the hatch when mayflies are floating in the
surface film trying to dry their wings so that they can fly away. It's
during this emergence stage of the hatch that fish feed most heavily on
these insects. It's also during this stage of the hatch that a fisherman
using a good dun pattern can clean up on the fish if he/she knows what to
look for. CDC flies float low in the surface film like an emerging
insect that is helpless until its wings dry. Tails and hackles can be
omitted if you wish and then this pattern will work as a caddis fly if
tied in the right sizes and colors. My favorite colors are a dun body
with a dun wing in a size 20 or 22 to match the Baetis mayfly that is so
common in the Black Hills and on the Bighorn river. I usually omit the
hackle so the fly will ride lower and more naturally in the surface film.
Of course, if you have questions about this or any other fly pattern,
e-mail me.
I'm always glad to be of service. Thanks and tight lines, Al
Campbell.
