Some background is necessary here. Why would Vincent Marinaro be so
important to me and my investigating? I had also been looking for any fly
that would look like the natural. That is, like the naturals as seen in my slant
tank. Following is a series of one of my hatchlings, Ephemeralla dorothea,
sub-imago (dun). The first picture shows the fly ahead of the window. Notice
how the insect rides on top of the film, and leaves a 'foot-print' pattern.
You can see that body color is of no great importance here. This is the pattern
a fish must 'key-in' on to be able to position himself for the rise. This the first
stimulus. If it is correct the fish will assume all others to be correct also. All he
has to go on is the foot-print pattern.
This is THE picture. This is the one, the first one that proved to me the
'ten-percent' law. The 'foot-print' pattern is there, the blank mid-range is present
and the tip of the wing is just coming into view at the edge of the window.
The above picture is an exact picture. It is the real thing. It is what a tied fly
must look like to be effective. None of the tied flies looked like this one.
In this picture the fly is into the window a little farther and has turned. I had not
trained him yet to face the camera.
At this point body color is relevant. This is the exact position a fish keeps
a fly as he rises in the water column for the take.
My last picture of this fly is taken from directly below.
Refer to the above pictures and observe the placement of the fly's parts as they
are seen in the series. This is how a tied fly should (must?) look to be effective.
Vincent Marinaro told me he had a fly that would look like it. That is why he was
so important to me.
