Beadhead Pheasant Tail

One of the best imitations of Baetis (blue-wing olive) mayfly nymphs. It also resembles a wide range of small, slender aquatic insects.

History:
Designed by English riverkeeper Frank Sawyer in the 1950s, originally without thread. The beadhead version, added later, became a gold standard for modern nymphing. Extremely effective in sizes 14–20.
