Here is my latest articulated streamer that I concocted to represent an adult crayfish. The fly comes in at around 3-3-1/2 inches and is what I would call a moderately weighted pattern that can be fished in a multitude of ways and with a floating or sinking line. So far she has racked up several species including northern pike, brown and rainbow trout, small and large mouth bass and even striped bass in the salt. Seconds for a great juvenile lobster pattern. Currently I tie it in the crayfish orange, olive/blue and tan colors but feel free to experiment.
