Surveyor Nymph

The Surveyor Nymph, also known as Egan's Tungsten Surveyor, is an attractor nymph pattern created by renowned fly fisherman Lance Egan. Inspired by the success of his Rainbow Warrior fly and the classic Hare's Ear Nymph, Egan designed the Surveyor to incorporate the translucency and flash of rainbow sow-scud dubbing, making it particularly effective in tailwater fisheries where sow bugs are prevalent.

When fishing a tungsten Surveyor, tuck the first mend downstream rather than upstream. That counterintuitive move flips the fly on its side for a moment, making the flashy red-and-pearl body flare—an underwater “flash trigger” that often draws strikes in pressured water.
