Giant Stonefly Nymph:
Again, let me mention that the Giant Stoneflies hatch during the night and deposit
their eggs during the night. Off hand, that may sound like they are not a factor in fly
fishing but they are. These nymphs live for three years and remain mostly under
rocks on the bottom of the fast water in riffles and runs. They only come out to feed
or when they emerge the one time in their lifetime. That's when they are most
susceptible to being eaten by trout. They migrate from the fast water areas to the
banks to hatch.

As I also mentioned before, once you start seeing a lot of shucks along the banks,
you have missed the hatch and the easiest time to catch trout on the Giant Stonefly
hatch. Ideally, you would have been fishing a nymph, especially late in the day and
early in the mornings. I doubt many of you fish early in the day this time of year. I do
every once in a while because I enjoy being out just past daylight. I also have found
that's a good time to catch trout on imitations of stonefly nymphs. If you don't fish
early, then fish the nymph late in the day before dark.

One way to tell when the hatch is about to begin is to check the nymphs. Their wing
pads will tell you within a week or two of their actually emerging. They will just about
be popped out. Also, it is often you can see the nymphs in the shallow water just
before they crawl out of the water to hatch.

You want to use the exact same method I just outlined a few days ago for fishing
imitations of the Little Yellow Stonefly nymphs. Imitate the nymphs migrating from the
fast water to the banks and keep the fly on the bottom. There is more information on
Perfect Fly Giant Black Stonefly section of the website.
