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 Sister Sedge (Caddisfly) - Part 1

The Little Sister Sedge gets its name because in essence, it is just a small
version of the
Hydropsyche and Ceratopsyche species. Their big sisters, primarily
the Cinnamon Sedges in the Eastern U. S., are the most abundant of all caddisflies
in trout streams. These caddisflies, or Little Sisters, are the second most abundant
of all caddisflies in trout waters. If these were present in just about any other
streams in the nation other than the freestone streams of Great Smoky Mountains
National Park, they would probably be the second most important caddisflies in the
stream. They exist in several streams in the Smokies but they are plentiful only in
Abrams. Like the
Ceratopsyche species, these are also fairly plentiful in
Cataloochee and Hazel Creeks.

These caddisflies hatch later in the season after most of their big sisters have
hatched or from about the first of May until the end of July depending on the
species. Trout eat them in three of the four stages of their life, the larva, pupa and
adult stages. They are a part of the net-spinning group of mayflies.

Since these are not plentiful in most of the park's streams, I will not spend a lot
of time detailing this hatch. If you happen to fish any of the local tailwaters in
Tennessee or North Carolina (actually anywhere else in the nation for that matter)
then you should find this information useful for those streams. In most tailwaters
they are the second most important caddisfly present.

You fish all three stages exactly like you fish the
Ceratopsyche (Cinnamon Sedge)
Hydropsyche (Spotted Sedge) hatch. The only difference in the two (Little Sisters
and Big Sisters) is the colors and size of the flies.

In case you are interested, these are the species known to exist in the park:
Cheumatopsyche campyla
Cheumatopsyche harwoodi  
Cheumatopsyche helma
Cheumatopsyche pasella
Cheumatopsyche speciosa

Tomorrow I will get into how you should fish imitations of these caddisflies.
