What it is
Hareline Buggy Nymph Legs are narrow-cut silicone legs for fly tying. The silicone has barred, speckled markings, stays durable on the hook, and the small diameter lets the legs wiggle and pulse underwater instead of looking stiff.
What to tie with it
Use it anywhere you want leg motion without adding bulk: stonefly nymph legs, shrimp and crayfish legs, and buggy stillwater nymph accents. You typically tie it in as paired legs through the thorax, as a few kicked-out strands at the sides, or as short feelers/antennae on crustacean patterns. It also fits trout spey-style flies where you want subtle movement in the profile.
Flies and the fish they're for
Pats Rubber Legs uses this material for the kicking legs that help sell a stonefly or big attractor nymph to trout in rivers, and it also crosses over as a general nymphing fly for other freshwater fish that eat big nymphs. Koz’s Caddis uses it for lively leg action that helps trigger trout in moving water when caddis are active. In a pine squirrel trout spey streamer, these legs add extra motion for swung presentations to trout in rivers and tailwaters.
How it compares
Compared to Hareline Crazy Legs, Buggy Nymph Legs are about half as thin and half the width, so you get the same silicone movement in a slimmer, more subtle package.
