The thing that strikes me from these pictures and others I've seen in books etc. is, in general, how similar a lot of them look. Mainly just a difference in size. So maybe that is why I've read that some dry fly anglers just worry about the size of the fly rather than an exact imitation? I've found that if I get the size right, then an adams or parachute adams often works well, even though the colour is totally wrong!
