Imitations of Stonelly Nymphs will
work throughout the season in many
of Yellowstone's streams.
Flies: Stoneflies
...............................................Fly Fishing Yellowstone National Park
A Firehole River Rainbow took a golden
stonefly imitation.
Stoneflies are certainly one of insects
you should imitate in the streams of
Yellowstone National Park. They are
present in all the streams and in very
abundant quantities. They exist in most
of all, if not all of them. Selecting a fly to
imitate them is a much simpler process
that selecting them for mayflies or
caddisflies. They have only two stages
of life anglers are interested in - the
nymph and the adults.
In some cases we offer a suggested
spent pattern to imitate the adults after
they have died and fell spent on the
water. Many of them don't fall into the
water, they fall on the banks.
By far the most important stage to
imitate is the nymph. That is because
they all crawl out of the water to hatch.
The only time the adults are going to be
on the water again is when the female
deposits here eggs or when the male
falls into the water after completing his
function in life. Often, depending on the
species, this occurs in the dark, at
night. Imitating the egg layers can be
effective and a fun thing to do if
everything is right for it but that is not
very often.

This is one of the most important
stoneflies in Yellowstone National Park..
Golden Stonefly
These are actually more important than
the Giant Salmonflies. You may have a
difficult time getting some anglers to
agree with me but I know for a fact there
are several times more Golden Stonefly
nymphs in the streams of Yellowstone
Park than there are Samonfly nymphs.
We have observed many steam samples
of these nymphs in just about every
stream in the park.
I don't want to degrade the Salmonfly by
any means. By stoneflies are important
but I do want to stress the importance of
the Goldens. They hatch close to the
same time the salmonflies hatch but they
usually start hatching just a little later and
usually don't finish hatching until a
couple of weeks after the salmonflies
hatch.
