Overview
Barr's Net Builder is a slender, realistic caddis larva imitation designed with a segmented body using wire or D-rib, typically in olive or chartreuse shades. The fly is tied on a curved scud-style hook to better mimic the natural shape of a caddis larva. The head often features a dubbed collar or a bit of peacock herl for contrast. The simplicity of the pattern makes it durable and effective, especially in tailwaters or spring creeks where caddis are prevalent. A tungsten bead can be added for depth if needed.
