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
isoperia
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 slightly 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. 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.
