Fly Fishing Yellowstone - Adult Salmonfly

Salmonflies deposit their eggs back in the water from the same area they
hatched from. They do this during the day as well as the evenings. At the right
time during this process, the opportunity will come along for some great dry fly
fishing. When the hatch is underway you can see the large stonflies very well
and you can also find their shucks along the banks where they have hatched. If
you will look closely at the bushes and grass along the banks, you will find the
Salmonflies. Sometimes you want have to even look for them. They will find you
and lite on you. They usually scare someone the first time this happen but they
are harmless.

These big stoneflies live a relatively long time out of the water. They are usually
easy to spot in the air as well as in the bushes and grass. There can be so
many of them that it makes you wonder how many were already eaten by the
trout. You may get the answer to that question in a direct response manner. The
trout may not eat your dry fly imitation of the adult. Usually when this happens
the trout will just come up and slap the fly around as if they were playing with it.
It makes you think you are going to catch one every cast and that you are just
not setting the hook properly. If this starts to occur it usually means the egg
laying process has just getting started. The trout are simply full of Salmonfly
nymphs. They can become gorged feeding on the huge nymphs and it may be
some time later before the trout become interested in eating the egg laying
adults. It also may mean there are plenty of Salmonflies still hatching. It is much
easier for the trout to catch the nymphs when they are moving to the banks to
hatch than it is for them to grab an egg laying female.

The females usually don't start depositing their eggs until a few days after the
hatch first starts. Just because you see a large number of stoneflies in the
bushes and air, doesn't mean that imitating them will be effective. You also have
to consider the fact that the trout may be full of the stonefly nymphs and will not
begin to actively feed for a while. If you are seeing a lot of adult stoneflies and
you are not catching trout on dry fly imitations of them, most likely you are
fishing a little early in the process. Either move a few miles downstream where
the hatch may have started earlier or wait a day or two to try again. At some
point in time the trout will begin to take them.
