Little Green Stonefly Nymphs:
Like most other stoneflies, the “Little Green Stoneflies” crawl out of the water to
hatch. When they do they tend to seek the slower moving, calm water that's in
close proximity to their normal fast water habitat. It's rare you will find their shucks
on banks where the water is swift against the bank or on boulders protruding out
of the fast water. Imitations of the nymphs will always be effective just before and
during a hatch.
You will notice that the Golden stoneflies start to hatch about the same time in
many places. Also, the Little Yellow Stoneflies, including the Yellow Sally, hatch
during the same time period that the Little Green Stoneflies hatch. I think that is
one reason little attention is paid to the Little Green Stoneflies. The other big
reason for this is that some of the species are confused by anglers as Little
Yellow Stoneflies, or Yellow Sallies. Some of the adults appear more yellow than
they do green but they are Chloroperlidae species.
The Little Green Stonefly nymphs are not green, they are brown. As with most all
other stonefly nymphs, you should imitate the nymphs migrating from their normal
fast water habitat to the banks and large boulders where they crawl out of the
water to hatch. Remember, this will be slower to moderate areas of water near
When you are imitating the nymphs, the main thing to remember is to keep the fly
on or very near the bottom. The Little Yellow stonefly nymphs crawl on the
bottom. They cannot swim.
I would not use a strike indicator. You cannot keep the nymph on the bottom
using an indicator unless the bottom is a constant level and that's almost never
the case in a fast water mountain stream.
Weight the Perfect Fly Little Green Stonefly nymph fly down by placing split shot
a few inches above the fly. If you are wading, allow the fly to swing all the way to
the banks in the areas you would expect the nymphs to crawl out to hatch.
If your fishing from the bank and have a clear enough area in which to do that,,
make certain you don't spook the trout looking for the nymphs up close to the
banks. Stay well back from the banks. If you first fish an area up close to the
bank, you can then move up to the bank and fish downstream from that point.
Make a down and across presentation, mend the line a time or two and allow the
fly to swing all the way back to the bank keeping the fly near the bottom. You can
then move downstream a couple of steps and repeat the process.
