The Adams is one of the most generic dry flies; it resembles many different kinds of trout food. While it is seldom the "right" fly, it is rarely the "wrong" fly. You should always carry a bunch of Adams or Parachute Adams in sizes 12-20 (but mostly 14-18) for unknown or unusual hatches or as a dry fly to use when there is no hatch.
A Female Adams is tied the same way, but with a small bit of yellow dubbing at the rear of the body to imitate a mayfly ready to lay eggs.
A Parachute Adams is tied with a white calftail post for a wing, then the brown and grizzly hackle is wrapped parachute-style around the post.
How to Fish
Dress the fly with floatant and use standard dry fly presentations.
