As the summer progresses, these little black flies work when no other terrestrials will do the trick. Small enough not to spook wary trout in low water but tantalizing enough to draw strikes. Per 3. Sizes: 12, 14, 16.
I recently participated in a fly swap with a dozen friends. Each of us provided 12 of our favorite fly. Everyone who saw them was favorably impressed with the quality of the Cabelas Flying Black Ants that I submitted. Now I need to order more for myself!
