The Adams fly requires no introduction; it is probably the most famous fly in all of history. It’s carried in the fly boxes of fishermen in every country where trout are found. It would probably be an understatement to claim that the Adams fly, with all its variations, has collectively caught more trout then any other fly pattern in existence. It can be used in a variety of waters, and, with its brownish-grayish coloration it imitates generally acceptable food items found almost anywhere in trout fishing environments. Most fishermen would agree that if they were allowed to use only one dry fly pattern — it would be the Adams (or some variation there of).
