Overview
This pattern from Fly Fish Food demonstrates the effectiveness of simplicity in leech design. Using a single rabbit zonker strip for both body and tail creates seamless movement from head to tail. The leech red color is particularly effective, providing the appearance of a bloodworm or natural leech. Can be tied in olive, black, brown, or purple variations to match local forage.

Behavior & presentation
- Natural Behavior
- These segmented aquatic worms swim between hunting zones with continuous wavelike undulations, their bodies creating rhythmic pulses that broadcast their location to nearby predators. The leech's persistent swimming motion and inability to escape quickly makes it a high-value target that trout pursue aggressively.
- Where Trout Eat It
- Trout intercept leeches throughout the water column in deeper runs, pools, and along weed edges in depths of 3-8 feet.
- How to Fish It
- Cast and sink before beginning slow 4-6 inch strips with 2-second pauses, allowing the rabbit fur to pulse and the bead to create jigging action on the pause.
- Best Water
- Work deep runs, pool tail-outs, weed edges, drop-offs, and structure where leeches migrate between feeding areas.
- Strike Type
- Feel a steady pull-down or line draw as fish swim away with the fly.
Fishing strategy
- Rigging Suggestions
- 7.5-9ft 2X-3X fluorocarbon leader. Heavier tippet handles larger fly and potential larger fish. Use floating line in shallow water, sink-tip or full sink in deeper presentations. Can be fished solo or as lead fly with smaller dropper.
- Seasonal Timing
- Effective year-round as leeches inhabit most waters throughout seasons. Peak activity occurs in spring and fall when water temperatures moderate. In winter, fish slowly and deeply. Summer fishing best during low-light periods because leeches are more active during dawn and dusk.
- Pro Tips
- Tungsten bead provides medium-fast sink rate appropriate for depths 3-8ft. Rabbit fur maintains movement throughout water column, with individual fibers pulsing even on slow retrieves. Red coloration provides excellent visibility to predatory fish.

Entomology
Leeches maintain a continuous undulating motion when swimming between hunting grounds, their segmented bodies creating fluid, wavelike movements through the water. Predatory fish respond instinctively to this motion pattern, associating the leech's pulsing profile with a calorie-dense meal that can't escape quickly.
