GEORGES' FLYBOX FIVE
The Stimulator is designed to do just what it says: stimulate trout into eating it. Tied to imitate a caddis fly—a large family of flies which have large, tent-like wings—most of its success comes on rivers and small lakes (Beaver, Mona, Moab). A dry fly (meaning it is fished on the surface of the water), a stimulator is one of the best flies to use when prospecting for trout when there is no active insect hatch.
There are hundreds of variations of beadheads, a term which refers to a small tungsten bead attached to the top of a nymph imitation. Typically the bead is for practical purposes: its relatively heavy weight sinks the fly to where the fish are, useful in the fast-flowing rivers common to Jasper. But the bead on Tremel’s bloodworm imitation—which could also be referred to as a chironomid imitation—has a dual purpose. It imitates the bubble of air in which nymphs rise to the surface after hatching. Use it on all lakes where you see tiny worm-like insects (chironomids) rising to the surface.
