What it is
Hareline Lateral Scale is a fly-tying flash material made from horizontally crimped Flashabou fibers. The crimp gives it a scaled, side-on look and a fluttering action in the water, with a pearl finish that holds up well.
What to tie with it
Use it to build lateral lines and scale accents on minnow and other baitfish patterns without adding bulk to the profile. It’s also a clean option for flashbacks, and it’s durable enough to incorporate into jigs, poppers, and other larger flies where you want shimmer and movement.
Flies and the fish they're for
On slim baitfish patterns, Lateral Scale is a natural fit for species that key on small forage, because it helps define that side profile and “scale” read without turning the fly into a tinsel bomb. Think streamer situations for largemouth and smallmouth bass in ponds and rivers, trout that are feeding on minnows in tailwaters and lakes, and saltwater baitfish eaters like redfish and striped bass on flats and along current seams, where a lateral line hint can be the trigger. It also makes sense on bigger profiles for pike and musky-style baitfish patterns, where durability and flash both matter.
