Comments About the Pattern
This pattern was initially developed to imitate the large adult orange stoneflies (Pteronarcys Californica) of the Pacific Northwest in the United States. In other colors and sizes, it can be used to imitate other stoneflies, caddis flies (sedges) and terrestrials such as hopper, crickets and even cicadas.
When fishing bead head or other weighted flies, the stimulator acts as an excellent strike indicator as it floats so well and sits rather high on the water. Although fish may be taking naturals deep below the surface, I have had the occasional fish take the indicator fly when there is actually no hatch.
In rare circumstances, the stimulator may be fished as a streamer. One early evening when fishing a stream in Massachusetts, I caught a 12 inch rainbow trout in a run while fishing the stimulator as a lone dry fly. Two casts later, in the same spot, while stripping the stimulator upstream just under the surface, I caught a 14 inch smallmouth bass. Go figure!
This is a very versatile pattern. I may be dressed with flash under or over the wing. Rubber legs may be attached underneath the thorax material, with ends extending beyond the eye and/or rearward just below the wing.
A great pattern with many techniques applicable to other fly patterns.
Tight lines! Fish On!!
