A Blooddot Fly with a chartreuse colored dot (yoke) triggers fish to feed during low light conditions in clear to slightly turbid water conditions. The body(albumin) is made from Egg colored Glo-bug material while the dot (yoke) is Chartreuse Glo-bug material. Sometimes a slight change in color will trigger a strike especially in pools where the fish have gone stale and ignore even the most realistic pattern to natural food.
