Mahogany Dun

The duns emerge in shallow, calmer water close to fast water as opposed to the
runs and riffles the nymphs live in. When the duns hatch, they usually are able to
avoid the current seams before they get caught up in them. Normally the water is
fairly warm and their wings dry rather fast. This means they leave the water quickly
after they emerge. This is completely unlike their close relatives, the Blue Quills that
hatch in the early spring. This means that you need to present our "Perfect Fly"
Dun in the calmer water, not the current seams or fast water as your may normally

Up and across presentations usually work best but if the water is very slick or
smooth, you may want to use a down and across presentation to get the drag-free
drift you need. This gets the tippet out of the view of the trout if done correctly. As
we said in the previous sections, these mayflies often hatch near the banks and
behind boulders where the water is calm and sometimes very shallow and clear. In
those cases you almost have to use a down and across or directly downstream
presentation for the fly to be effective.

Long, light leaders and tippets help fool the trout in the calmer water. This can be a
matter of casting to a spot, picking the line up and casting to another likely spot.
Sometimes, getting a long drag free drift is about impossible if you place the fly in
the type of water the Mahogany Duns hatch in. The fast water will catch the leader
and line and drag the fly out of the slow water. In these cases, you may have to
make a lot of cast where the fly remains on the water for only a short period of time.

"Perfect Fly" Mahogany Dun
Note: This is a fairly lousy image of the fly. It is actually a nice looking fly but like the
real ones, it isn't very colorful. All though it make little or no difference, there are
three tail but you can barely see the middle one in this image.
