Insects and other foods the trout may be eating:
1.   Blue-winged Olives - mostly Little BWO - Isolated hatches
2.   Giant Black Stoneflies - hatching
3.   Cinnamon Caddis - Mostly Abrams Creek
4    Light Cahills - hatching
5.   Midges - hatching in isolated locations
6.   Little Short-horned Sedges - should hatch randomly for 2-3 months
7.   American March Browns - hatching but randomly in isolated locations
8.   Streamers - matching sculpin, baitfish and small crawfish
9.   Little Yellow Stoneflies - hatching
10. Green Sedges - hatching
11. Little Sister Caddisflies - Mostly Abrams Creek
12. Eastern Pale Evening Duns - (called Sulfurs by some)
13. Sulphurs - hatching in isolated areas
14. Golden Stonefly - hatching
15. Little Green Stonefly - hatching

Little Green Stonefly - Nymphs:
The “Little Green Stonefly” Nymphs are similar to the other smaller stonefly nymphs
insofar as what meets the eye. There are of course differences only important to
the scientists. The biggest difference I have found and confirmed by other writings
is that they tend to live in move moderate water. They don't necessarily have to
have real fast water. They do have to have a lot of oxygen in the water. It must be
cool enough to hold plenty of dissolved oxygen but you don't have to have rapid
moving water.

The biggest hatch I have even seen occurred one late afternoon in Virginia. It was a
small stream that flowed along a state highway we just ran into. Later we found out
it was a stocked stream but also had some wild trout. The hatch was fairly large with
hundreds of flies. The big difference we noticed was that the stoneflies were
hatching in shallow pools, mostly near the end of the pool where the water was
flowing well. They were hatching and the females from previous hatches were laying
eggs in the same place. The bushes along the stream had lots of the Little Greens.
We caught several trout, all stockers.

The best hatches we have found in the Smokies took place in Hazel Creeks and
Cataloochee Creeks. Each time we have found them, we noticed they were at the
end of pools. I cannot say that is always the case because I doubt it is. We have
found some species in all of our stream samples from all the creeks and small rivers
in the park. These nymphs were in the riffles and runs.

Nymph Presentation:
The best way we have found to present the nymph at the ends of the pools is to
use a down and across presentation. Mend the line to get the lightly weighted
nymph down to the bottom and let it swing all the way to the bank near the tail end
of the pool.

I feel sure they would work presented in runs and riffles using other methods but we
have only fished our "Perfect Fly" specific imitation when we have found them
hatching. By the way, notice the nymphs are brown, not green or yellow.
