Hatches Made Easy:

Little Yellow Stoneflies (Perlodidae and Peltoperlidae Family) - Adults


The different species of the Little Yellow Stoneflies deposit their eggs at different
times of the day depending on the species and the time of year they hatched.
Some of them only do that during the evenings. Most of the Summer Stoneflies
(Peltoperlidae family) deposit their eggs during the evenings. The
species, or Yellow Sallies, usually start depositing their eggs in the afternoons
prior to dark. This is one thing about the Yellow Sally that makes them important.
You should actually observe stoneflies depositing their eggs before
you spend time imitating the process
. They are large enough that you can
easily see them dropping down to the surface, usually bouncing along on the
surface, dropping their eggs. Sometimes they will lite on the surface for a short
time but for the most part, they knock their eggs off by touching the surface.
They will usually deposit their eggs in the riffles and runs. Where ever you see
them depositing their eggs is where you should fish imitations of the adult. The
different species of the Little Yellow Stoneflies are different sizes.
You should
match the size as close as possible
. You should be able to find an adult
along the banks in the bushes or grass.
It would be nice if you could imitate the actual bouncing type of action but I can't
make my imitation fly again after it hits the water. You can jerk the fly around
some but I end up spooking more trout than I fool. I think it is best to use a drag
free drift. Up and across cast work best for this.
I have caught as many trout imitating the egg laying Yellow Sallies as I have
caught in a short time span imitating any insect in the Great Smoky Mountains
National Park. During the month of August, three years ago, Angie and I caught
at least a dozen or more trout in less than two hours of the day, every day for
over two weeks. We were imitating one of the species of Little Summer Stoneflies
that were hatching. It was as sure of a thing as we have experienced in the
This hatch and subsequent egg laying activity occurred at the bridge on Porters
Creek where it intersects the Middle Prong of the Little Pigeon River. We just
walked out on the bridge late in the afternoons, waited until the sky was full of
stoneflies and fished just below and above the bridge. During that same time
period, fishing reports all stated fishing in the park was slow. Most anglers were
not fishing at all. I would estimate that we caught at least 150 or more trout
during that two week time period all very late in the day. We probably caught
some of the same trout several times because all of them came within the same
fifty yard stretch of water.
By the way, this is a perfect example of why you should not pay any attention to
fishing reports. You should go whenever you can go and see for yourself. You
should learn to catch trout when conditions are not so great. That just adds to
the satisfaction from fishing.
Remember, you
can never become better than anyone you copy.  A copy
of something is usually not as good as the original.  It is never better.
