Mercury Mayfly, Dorsey
Pat Dorsey's Mercury Baetis and PMD are tried and true. They're lean, buggy and simple.
Trout love swimming Baetis nymphs during a hatch and will travel a far distance to eat. However, the imitation needs to be exact in size and color. It's a great attractor, but can be an effective point fly as well.
Fish them larger in the Spring (18-22) and smaller in the Fall (20-24).
