Beeticator

Denny Owens - Caddisfly

Hook: dry fly #12 (or smaller)
Thread: to match foam
Body: 2mm bright green tying foam (yellow is also good) cut to 1in by 1/8 in
Notes: I use these as strike indicators when trout are grabbing the indicator instead of the nymph.  They work well alone when beetles are active. Also, great for bluegills.
