the early mornings, they usually hatch late in the afternoons, just before dark. It greatly
depends on the species of Mahogany Dun. These spinners fall over the same water they
hatch in which is calmer areas nearby moderate to fast moving water. In most cases the
spent spinners collect at the ends of the long slow runs and riffles and at the heads of
pools.
Presentation:
Most of the time, a down and across presentation or direct downstream slack cast is
needed, especially if the water is very smooth. Again, this depends on the time of year
the particular species hatch. If you can get by with it use an up stream or up and across
presentation but most of the time a down stream approach is needed.
You can almost count on having to use a longer, lighter leader and tippet. It is rare these
mayflies are found in water heavy or rough enough to get by with anything close to being
on the heavy side. Normally a six or seven X tippet is needed to prevent spooking the
trout feeding on the spent spinners.
Often these spinners fall near dark and seeing the fly is almost impossible. It is possible
to fish another move visible fly a foot or two ahead of the Mahogany Dun Spinner but we
prefer to watch for the small rises and slight leader and line movement to detect takes.
