Mayfly from a trout's view
Hope these links work. It's pretty cool and might give you fly addicts something to think about as far as presentation and tying. I put them on our CFFA page to aid our upcoming beginners in our Fly Fishing school but I learned some things as well a seasoned veteran. One is from across the pond and very interesting on how they ensure a good survival of a species.
Thanks Gary, that explains for me why early spring emergers look best with the bodies wrapped in turkey biots. The striations of alternating brown and tan colors are realistic.
