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


Golden Stoneflies:
As early as I started with the hatches this year, it looks like I may still get behind
covering all the important hatches in Great Smoky Mountains National Park. The
Golden Stoneflies and the Little Green Stoneflies have started to hatch in a few
places and I haven't mentioned them yet. The most important of these two families
of stoneflies is the Golden Stoneflies. The Little Greens don't hatch everywhere in
the park and tend to be isolated. The Goldens are represented just about
anywhere there is fast water and that covers most every section of  every stream in
the park.

Golden Stoneflies are species belonging to the Perlidae family of stoneflies. There
are several genera and numerous species of them in the park but fortunately, they
all look and behave about the same. There is nothing specific to any one species of
them to warrants any special attention.

These are fairly large stoneflies. A few species of them are about as large as the
Giant Stoneflies. They range from about an inch long up to three inches long. The
nymphs live from one to three years, so they are around in all sizes. That doesn't
necessarily mean they are available for trout to eat. They are in the water, of
course, but they stay well hidden.

You hear and read about nymphs being caught in the drift, but that too, is far more
the product of a few writer's imagination than fact. We have checked the "drift"
using professional equipment in just about all the major streams in the park
throughout a 24 hour period of time on numerous occasions to find almost nothing
in the drift. What we did find was very small and almost none of the insects were
stoneflies. So when you hear someone say "fish a nymph" - there are always
nymphs in the drift - you better be aware that is pure speculation without any
foundation.

The only time the stoneflies, including the stoneflies (and most mayfly nymphs for
that matter) become easy prey for trout is just prior to the hatch. All stoneflies crawl
out of the water to hatch and they can't do that and stay hidden.
