Needleflies (Stoneflies) - Adults
The adult female Needlefly deposits her eggs late in the late afternoons. It most
likely continues on into the evenings on warmer days. The adults flutter just above
the surface and actually touch the water with their wings while they are still flying. It
is common to see trout eating the egg layers on the surface in the late summer and
early Fall. It seems most of the activity is in the high elevation streams although you
will find them about everywhere there is fast water.

There is an amazing difference in the way these stoneflies look flying than they
look when they are not flying. They look much like caddisflies in the air but as you
can see, they are small very narrow, long flies. Flying they look much larger than
they actually are. I suspect many anglers think these stoneflies are caddisflies.
By the way, I have forgotten to mention it before, but these stoneflies are
sometimes called "Rolled Winged Stoneflies".

Catching trout on our "Perfect Fly" Needlefly Adult is fairly simple. Just get the fly on
the water wherever you see them depositing their eggs. We usually work upstream
in the small streams working the small pools out, including the tails and heads of it.
Most of the time the females are near the heads of the pools where the faster water
from the riffle or run enters the pool. Cast the fly in the riffles or run and allow it to
drift into the head of the pool.
