KISS A Bug Series - Giant Black Stoneflies - Part 2

The Giant Black Stoneflies adults can live up to four weeks but average living a week or two.
About the only way you are going to find one of these large bugs is to catch one near a light.
It's fairly easy to do it if your camping but if not, there can be a large hatch going on and you
may never see an adult. During the day, they tend to stay well hidden during the day.

For some reason they have a tendency to stay up high in the trees as opposed to lower limbs
and bushes. About your only chance to spot one during the day is to start looking high
overhead very late in the afternoon. We had a time capturing one of them in the park for our
Stonefly DVD a few years ago. We ended up setting out some light traps. That got us about
ten dozen in one night. The bottom line to this is that you will not normally be able to detect the
hatch by finding the adults during the day.

The best clue that a hatch is occurring, or I should say "has occurred", is to find the empty
shucks along the banks or on rocks and boulders where they have crawled out of the water to
hatch. Finding a shuck or empty skin of the nymph left to dry when one of the large
stoneflies changed from a nymph to an adult or fully grown fly is about the only other way to
know for sure if they are hatching.  

If you know a hatch is underway you should try fishing an imitation of the adult Giant Black
Stonefly. If it happens to be cloudy, or if the skies are heavily overcast, you may want to start
fishing the adult earlier in the day as much as a couple of hours before it is completely dark.
Even though the stoneflies deposit their eggs mostly during the evenings, the trout may have
seen a few of them and may respond by taking the fly.

There's not anything wrong with fishing the imitation on into the night in streams that permit
fishing at nigh. It isn't legal to do that in Great Smoky Mountains National Park. Doing so in the
fast water, freestone streams where these stoneflies exist can be dangerous, so you want to
be careful if you do attempt it. If you are wading, it's best to get into the position in the stream
before dark and move around as little as possible. If you hear a trout splash the surface, you
would want to cast to the sound or disturbed area if you can see it. There is nothing wrong with
casting all around you because it is not a good idea to do much wading in the dark.

If you are fishing a stream with fairly clear banks where trees or other obstructions won't
interfere with your backcast, then fishing from the banks would  be an optional way to fish after
dark. Once the trout start seeing the egg laying activity occurring during the evenings, they
become far more prone to take an imitation of the adult. We have caught trout very early in the
morning with our Giant Black Stonefly imitation. We have also done well late in the day once
we knew a hatch had occurred. I think they tend to hit the flies long after the hatch and egg
laying activity has ended.
