The MOP04 combines a beige Mop caterpillar with a UV effect and an marbled orange bead. The body is attached loosely to the hook shank, allowing the material to move freely in the water.
The #16 size features a 2.8 mm bead; the #14 version features a 3.3 mm bead. This beige Mop with orange contrast is sold in packs of 3 flies.
