Krystal Egg Hot Orange Nugget
This is one of the egg series of flies that are designed to imitate Trout or Salmon eggs drifting in the river current. These are very popular in Alaska where Trout and Char follow the spawning salmon, they are often fished on a short leader under a sight indicator. They have been known to work on stillwaters as well, maybe they are taken for a Trout pellet!
Available from Hartley Fly.
