Here is a fairly random selection of fly descriptions. The factors involved in
determining whether a fly makes it to this list are extremely complex, involving
among other things:
1.)
The ability of the fly to catch fish, in the area you are fishing.
2.)
The ability of myself to tye a flie that looks like what the insect looks like.
3.)
The ability of my camera to take a picture so that I can show the flie in a picture that is veiwable.
