measure the angle on a typical dry and it is about 70 deg.+/- from the head of the fly - but- measure the angle of the wing of a real mayfly and the angle is 70 deg.+/- from the tail.

why?????

other than thats the way it is done....

i find myself counting micro fibbets to be realistic but then i proceed to tie the wings at the wrong angle like i learned in class....

if we tie to match does it impact the way the fly floats? we know they catch fish but why the fish don't laugh at the fly with the backward wings - i don't know ... or are the naturals made wrong?
