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) - Pupa - Part 3

The Little Sister pupae swim to the surface to hatch. It is easy for the trout to eat at
that time. As with many other caddisfly hatches, the problem is determining when a
hatch is underway. Often the caddisflies are emerging at the same time they are
depositing their eggs. If not, you will probably not notice the hatch or see the fish
feeding on them.
Trout eat them as they swim (aided by air bubbles) to the surface. Occasionally the
trout will jump out of the water eating the pupae. The hatch usually happens in the
late afternoon but later in the year, it may not occur until dusk.

Pupae Presentation:
Imitations of the pupae should be presented in the same manner as the larva
imitation except that you would not weight the fly as much. Depending on the water
depth it may not need any extra weight.

If you determine that they are emerging in a particular area of the riffles then you
would want your fly to end up rising to the surface in that same area. Cast the pupa
imitation down and across. You want the fly to swing downstream near the bottom
and then rise to the surface. To do that, just stop the swing of the rod when the fly
is directly downstream from your position.
