FLIES - HOW TO SELECT A FLY
Selecting a fly to
fish is a question that long books have been
written about. We have a number of
suggestions on where to start with fly
selection. My father once said long ago
that the difference between a fact and a rule is
rules have exceptions and facts do not.
What follows are rules to which any knowledgeable
fly fisher can cite exceptions, however, they are
a good measure of what you need to know for
making a good fly choice.
DON'T RUSH
TO CAST
Observation is the
first order of business and the more you know and
have read about insects the better you will be
able to interpret the clues you see. So hit
the books so you know the difference between
mayflies, caddis flies, stone flies,
terrestrials, etc. The Latin names of these
bugs are not important. What is important
is size, general shape, color, and aquatic
habitat (fast riffles or slow runs) and, finally
where we come in the critical question, "do
I have flies to imitate them?"
Every fishing trip
is a riddle, and solving that riddle is a
lot of the fun. If you don't think so tie
on a size 14 Elk Hair caddis and pitch it
out.
OVER WATER
ACTION?
Watch for
signs of fish feeding at or near the
surface. NOTE: Trout tend to feed at the
top or at the bottom not so much in the middle of
the water column. Shake the stream side
bushes to get a look at what type, size, and
color of the bugs have hatched in the recent
past. Are there ants, hoppers or other
terrestrials about.?
Watch the insect
eating birds around the water particularly on
streams. Many birds feed on the same
hatches as the fish. Hatches occur on the
same schedule for days at a time. The birds
will gather and get nervous just before a hatch
begins. Look for groups of birds on over
head perches with occasional individuals
swooping down to the water for a look. When a
hatch is beginning the birds can take every bug
leaving you none to observe. But many birds
working the water is a sure sign that something
is going on.
UNDERWATER
ACTION?
To check the
underwater action build or buy a
seine. Get a couple of broom handle
pieces about 20 inches long and staple window
screen material between them. On flowing
water place your seine across the current
and kick over the rocks or weeds up stream.
A buddy helps, but a lab can work.
"Trout dinner" ends up in the
net. Congratulations! You now know
more about what to use on this stretch of water
right now than 95% of all fishermen. It
will take experience and study to predict what
dry flies these nymphs will become but 75% to 90%
of a trout's diet is underwater fare.
It is a little
more difficult on lakes but if there are weed
beds you can pull up a small quantity of weeds
lay them on the screen to prevent escapees and
sort through the material.
Note that baitfish
don't end up in nets and that most big trout eat
things like small fish, crayfish and other large
food "packages" that take less energy
to catch than they offer. So don't overlook
streamers and such.
FLY
FINE TUNING
GENERAL
SIZE: A particular type of insects hatching at
the beginning of the season are the largest and
each succeeding group will be smaller. For
instance Callibaetis May Flies typically start at
size #12 for the first generation of the season,
size #14 for the second generation mid-summer and
#16 for the late summer and early
fall. The basic rule is to start your
season with the larger flies used in an area and
get progressively smaller as the season
progresses. Two glaring exceptions to this
are hoppers which tend to get bigger during
the season and the October Caddis ( size #8 ) of
western rivers.
STREAMER AND OTHER
CRITTER NOTE: Baitfish start with large numbers
of smaller fish and grow over the season so you
end up with a smaller number of larger
baitfish. Crayfish and hoppers also
increase in size during the season. So
start small and work up!
COLOR:
During the cool weather months of spring and fall
as well as on overcast rainy days the flies that generally
hatch will be dark in color. This
allows them to absorb heat and get their motors
revved up for flying.
During the hot
weather season adult insects will be light colors
( Light Cahill - Little Yellow Sally - Pale
Morning Dun ) to reflect the suns heat to
prevent dehydration. Nymphs: These
underwater bottom dwellers will be the same color
as the bottom they live in, pick up a piece or
rock or gravel and take a look.
TIP: During times
of high or off colored water and lowered
visibility use larger black nymphs which will be
more easily be seen in these conditions.
FLOATATION
& WATER TYPE : Take into consideration
how fast and rough the water surface is. In
life there are trade offs, to get more of one
thing you must forego something else.
For dry flies floatability and exact imitation
are at cross purposes. The Adams family of
flies is a good example. The Irresistible
has a plump, spun deer hair body and is heavily
hackled. In heavy fast water the fish have
only a split second to hit or let it go and this
pattern was designed to stay on top of this
water. The next Adams descending order of
floatability is the standard Adams. The fly
sits on the water on it's tail and hackle.
The hook is suspended above the surface. This is
a medium water tie giving up some floatation and
gaining imitative value. The next is the
Parachute Adams. This fly sits with its
tail & body in the film and the hook below
the surface. This is an emerger pattern
achieving more exact imitation by sacrificing
floatability so it suits calm and
stillwaters. Adams Crippled Mayfly is
an interesting design. To fish it properly
you wet the marabou body and tail with
saliva. Use floatant on the hackle and post
and the fly will ride vertically hanging by
the hackle. Finally there is the
Compara Dun style in Adams color. The
Compara Dun style has no hackle and when viewed
from below is as close as we have come to a may
fly as seen from below the surface. This is
the style for slow moving, smooth topped spring
creeks and glassy smooth still waters. With
some experience you can take one look at a dry
fly and judge its relative floatation vs.
imitative place.
