Insects and other foods the trout may be eating:
1. Blue-winged Olives - mostly Little BWO - Isolated hatches
2. Giant Black Stoneflies - starting any day, nymphs active
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. Eastern Green Drakes - should be starting in Abrams Creek
11. Green Sedges - hatching
12. Little Sister Caddisflies - Mostly Abrams Creek
13. Eastern Pale Evening Duns - starting any day (called Sulfurs by some)
Little Yellow Stoneflies (Yellow Sally)
Last year, April 2, 2008, I ran the article below about the Little Yellow Stoneflies. It is
now a part of our "Hatches Made Easy" articles. Before I get into how I fish this
hatch, I wanted to re-run the introductory article so that you understand what
makeup the stoneflies that anglers call Yellow Sallies. It is rare that species from
two complete different "families" of an insect are included under the same common
name. There is one good thing about all of this. All of these stoneflies behave the
same when they hatch. The nymphs crawl out of the water to hatch and they female
egg layers deposit their eggs about the same way. The times of the hatch varies
considerably not only from a time of year but also from a time of day standpoint.
Other than that, everything is about the same, so all in all it makes little difference.
Two different families of stoneflies are properly called "Little Yellow Stoneflies". I
have noticed that in the Smokies most anglers incorrectly refer to just
about all the species of Little Yellow Stoneflies as "Yellow Sallies". The
Yellow Sallies are species of the Perlodidae Isoperla genus of stoneflies.
The Peltoperlidae Family of stoneflies, correctly referred to as roachflies, are
commonly called Little Yellow Summer Stones. They are also incorrectly called
Yellow Sallies by some anglers.
Some of the species of Little Brown Stoneflies have a lot of yellow in them. I have
even heard some of them called Yellow Sallies. That is why you will hear anglers
talking about seeing Yellow Sallies from March through November.
Some species of the Periodidae family, other than the Isoperia species, hatch as
early as the first of March. In the Smokies, the Yellow Sallies hatch from the last
of May to the second week of July. One species hatch the last two or three
weeks of September.
The Peltoperlidae species, or Little Yellow Summer Stones, hatch during the
summer months, from about the first of July until the second week of September.
In other words, there are species of these two families of stoneflies hatching for
a very long period of time. That is why some local anglers incorrectly call all of
these stoneflies, Yellow Sallies.
These are the known species of Little Yellow Stoneflies that exist in the Smokies:
Family Perlodidae - Perlodid Stoneflies
Isoperla bellona (Yellow Sally)
Isoperla distincta (Yellow Sally)
Isoperla frisoni (Yellow Sally)
Isoperla holochlora (Yellow Sally)
Isoperla lata (Yellow Sally)
Isoperla orata (Yellow Sally)
Isoperla similis (Yellow Sally)
Family Peltoperlidae - Roachlike Stoneflies
The Great Smoky Mountains National Park has one of the most diverse
populations of stoneflies of any area of the United States. They are a very
important trout food. Of all the species of stoneflies, the Little Yellow
Stoneflies are the most important ones for anglers to imitate.
