Bitters were originally developed for Bonefish on the flats around Belize. They have now been proven to work all over the world. This fly will catch a variety of saltwater fish and freshwater anglers are finding the Amber or Brown Bitter to be effective for Carp, Bass, Panfish and many others. This pattern will imitate small crabs, shrimp, urchins, crayfish and other items fish feed on. The glue covered eyes and synthetic materials create a translucent silhouette that fish find irresistible.
