Just An Interesting Occurrence (At least to me):
While my friends were here visiting last week and I was introducing them to fishing  
the Smokies and our local tailwaters for trout, others were busy fishing Frank's
famous Soft Head lures. Frank Jr. called to tell us he was headed to St. Thomas in
the U. S. Virgin Islands for a week of fishing the Annual Boy Scout's Marlin
Tournament. Frank told him fine and commented he had fished it many times
before. I commented I had fished it once and we continued to fish for six inch trout
without a single care what anyone else was doing. When Shelley and Frank
returned home to their Florida Ranch, they received an email and attached video
from James Kontos. His boat had won approximately $423,000.00 in the Ocean City
White Marlin Tournament by catching a 1,010 blue marlin on one of Frank's
Softhead Lures. Well, that's cool except for the following.  We were perfectly fine
fishing for 6 inch trout
except we didn't win $400,000.00 doing it. However, it did
remind me to post the following Perfect Rule. If anyone wins anything fishing one of
my "Perfect Flies", they are required to immediately cut a check made payable to
yours truly in the amount of 50% of the winnings. Frank forgot to do that.

Adult Needle Stoneflies:
I have caught about as many brook trout during the time they were feeding on the
little adult Needle Stoneflies depositing their eggs as it's possible to catch
considering you have to reel in the fish, release it and then cast again. What's
amazing is that sometimes you can catch several out of the same pool when you
would think all the noise, splashes and movement going on would spook every trout
in the pool. I guess they loose some caution and really focus on the stoneflies
dipping down and touching the water to drop their eggs. This usually happens late
in the day just before dark in about an hour or so. The rainbows will also hit them
aggressively but it seems they are more cautious about it. The Needlefly egg laying
activity will rival any Yellow Sally egg laying activity.

By the way, there will be some stoneflies local anglers call Yellow Sallies that will
also begin to appear soon. They are also on the
fly list but the hatches are far less
in intensity than they are during the Spring. The Yellow Sally is the common name
for an
Isoperla bilineata. The species of Little Yellow Stoneflies that hatch in the Fall
are in the same family but not the
Isoperla genus. This doesn't make any difference
so far as how you fish the hatch. I am only providing the info as an explanation of
why the so called "Yellow Sally" hatch last so long. By the way, their nymphs are not
yellow like the Needlefly nymphs. Yellow Sally nymphs are brown.

If the water is exposed to much light, meaning the stream isn't enclosed by a canopy
of tree limbs and surrounded by thick bushes, it would probably be past the park's
legal fishing hours when the egg laying occurs. However, on most of the small
streams, especially those surrounded by rhododendrun bushes or those down in a
deep ravine type of area, it usually gets fairly dark well before thirty minutes after
official sunset.

About the only secret to fishing an imitation of the adult Needlefly is to present it in
the same place you see the real ones depositing their eggs. It usually want stay on
the water but a few seconds.
