This Week's Featured Trout Food - Little Green Stoneflies
Little Green Stoneflies are members of the Chloroperlidae family. They are very similar to the “Little Yellow”
stoneflies. In fact, contrary to what the name indicates, the Little Green Stoneflies are sometimes yellow. Many
are chartreuse. Most of them have green wings and green bodies though. Trout eat both the nymphs and the
egg laying adult females.

The Little Green Stoneflies are small to medium sized stoneflies that emerge in the spring and summer months.
Although they are never any super hatches, the
long emergence period of anywhere from thirty to sixty
days, makes the members of this family important to anglers.

One thing about the Little Greens that's easily recognized is that all of them have short tails. That one thing
doesn't identify them from some other family members but it culls a great many.

Like most stoneflies, cold mountain streams provide an excellent habitat for the Little Green Stoneflies. These
insects must have highly oxygenated water to survive. You won't find them in slow moving streams.
.
The
haploperla brevis, a LIttle Green Stonefly, is often called a "Little Yellow Stonefly”, Yellow Sally, and
sometimes, the “Wee Yellow” Stonefly”. I'm mentioning it separately because it's often confused with the Little
Yellows. It's a small yellow-green winged fly with a green body.

The Little Green Stonefly nymph is a clinger nymph that lives just under one year. Like all stoneflies the
nymphs don't hatch in the water. They crawl out on the banks, rocks and boulders to emerge into adults.

They don't seem to hatch in a highly consistent manner, so it's not so easy to known as to when you should
expect to encounter them on many trout streams. Our hatch charts pin the hatch times down as close as
possible but you really just have to keep an eye out for them to know for sure. One thing for certain is that you
don't want to discover a hatch or egg laying activity without having imitations of them. You should be prepared.
Imitations of the nymphs will always be effective just before and during a hatch.

Nymphs:
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 fast
water.

When you are imitating the nymphs, the main thing to remember is to keep the fly on or very near the bottom.
The Little Green 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

Adults:
Some species lay their eggs during the daylight hours, usually in the afternoon, but are much more prone to
do so late or during the evening hours. Normally, this activity is not that intense but could be on a given stream
at a certain date in time. If you observe any activity, you should certainly try the Perfect Fly Little Green
Stonefly adult imitation.

On more than one occasion, we have found some rather very large hatches where the egg layers were in full
swing in the late afternoons during approaching thunderstorms. We were able to catch several trout on an
adult imitation on each occasion in a very short time. Those particular hatches took place in mid June two
straight years in a row in Great Smoky Mountains National Park. I am not sure which species of Little Green
Stonefly they were but I did note that they were hatching in the moderately flowing water, not fast moving
pocket water.

I would suggest that you always carry at least a couple of Perfect Fly Little Green Stonefly Adult imitations in
case you encounter a hatch of these stoneflies. In most cases, during the egg laying event, an up and across
presentation of an adult imitation works just fine. The problem many anglers have with these and other
stoneflies is they stop fishing too early in the afternoons. If you fish late in the day you can often find the egg
laying activity occurring when there's still plenty of light. A very cloudy or drizzling rainy afternoon is the best
conditions to find them depositing their eggs. The activity will start earlier in the afternoon and last much longer
while there is plenty of light left.

The type of presentation you make isn't really that important. You just want to get the fly in the same areas the
Little Green Stoneflies are laying thier eggs. They are easy to see and dart across the surface trying to knock
the eggs off although they also lite on the water for a few seconds at times.
