Behavior & presentation

Natural Behavior
Blood leeches pulse through lake water with distinctive elongation-contraction swimming, their bright red bodies signaling high blood content. Lake trout associate this coloration with vulnerable, nutrient-dense prey that swims slowly enough for easy interception.
Where Trout Eat It
Cruising trout intercept swimming leeches throughout the water column in lakes and ponds, particularly along weed edges and over shoals. Drop-offs funnel migrating leeches into ambush zones.
How to Fish It
Indicator fishing at specific depths or slow hand-twist retrieves activate the marabou's natural undulation. Minimal angler input allows the materials to provide lifelike motion.
Best Water
Work weed edges where leeches hunt for prey, shoals that cruising trout patrol, and drop-offs that concentrate vertical migrations.
Strike Type
Steady pull-downs or gradual line draws signal fish swimming away with the fly, requiring firm strip-sets.

Fishing strategy

Rigging Suggestions
Fish on 12-15 foot leader with 5X-6X fluorocarbon tippet under a sensitive strike indicator. The bead provides adequate weight for shoal presentations.
Seasonal Timing
effectiveness in BC Interior lakes and similar lake environments. Blood leeches are present throughout the year, making this a reliable searching pattern.
Pro Tips
The blood red marabou provides excellent visibility in various water conditions. The bead ensures proper sink rate for reaching cruising trout while the marabou tail creates enticing movement at rest.

Entomology

Blood leeches pulse through stillwater environments with a distinctive swimming style, their bodies elongating and contracting as they search for fish hosts or invertebrate prey. The bright red coloration that makes them visually striking also signals high blood content, triggering feeding responses from lake-dwelling trout that associate this color with vulnerable, nutrient-dense prey.
