LeechMayer's Mini Jig Leech

Mayer's Mini Jig Leech is Tim Cammisa's jig hook adaptation of Landon Mayer's Mini Leech featuring a UV-resin coated Krystal Flash body. The jig hook design reduces snags while the green flash body adds visual appeal in clear water. A modern competition-style take on the proven Mini Leech formula.

Mayer's Mini Jig Leech fly pattern - imitates Leeches tied for Trout

Overview

This pattern variation by Tim Cammisa demonstrates how small modifications can enhance classic designs. The Krystal Flash body coated with UV resin creates a durable, translucent body that catches light differently than traditional materials. The gray ostrich collar provides a subtle transition from the bright body to the dark squirrel wing. Popular in competition fishing where durability and fish-catching ability are equally important.

Materials

Hook: Hanak H 450 BL, #10
Thread: Semperfli Nano Silk 18/0, black
Bead: Slotted tungsten bead, 3.5mm, silver
Body: Krystal Flash, green, coated with Solarez Bone Dry UV resin
Wing: Micro pine squirrel zonker strip, black
Collar: Ostrich herl, gray

Behavior & Presentation

Natural Behavior: Small leeches caught in current tumble erratically while attempting to regain swimming control, their flash-enhanced bodies visible against clean substrate. Trout in faster zones target these struggling invertebrates drifting helplessly through feeding lanes.

Where Trout Eat It: Bottom to mid-column in deeper runs and pools where jig action shines, with clear western rivers allowing flash visibility. Structure areas concentrate drifting prey into predictable lanes.

How to Fish It: Euro nymphing with tight-line contact maximizes jig action through aggressive structure drifts. In lakes, slow hand-twist retrieves with pauses let the flash body catch available light.

Best Water: Target deeper runs with structure for jig advantage, pockets near rocks, and current breaks that concentrate tumbling prey in western tailwaters.

Strike Type: Sighter sags, ticks, or drift pauses indicate takes requiring immediate response in tight-line presentations.

Fishing Strategy

Rigging Suggestions: 10-12ft euro leader with 5X-6X fluorocarbon. Works excellently as point fly in two-nymph euro rig with lighter attractor pattern as dropper. Tungsten bead provides sufficient weight for most euro presentations without additional weight.

Seasonal Timing: Effective year-round with peak performance in spring and fall. Flash body particularly effective in clear water typical of western tailwaters and spring creeks. Winter fishing productive in slower, deeper water. Select for clear water conditions where flash body provides additional attraction without bulk because clarity allows trout to see flash trigger.

Pro Tips: 3.5mm tungsten bead provides rapid sink rates for reaching holding fish quickly. Krystal Flash body reflects available light, creating flash visible in clear water. UV resin coating creates smooth, durable surface maintaining appearance through multiple fish catches.

Entomology

Leeches caught in current lose their typical undulating rhythm and tumble helplessly while attempting to regain swimming control, their normally graceful movements replaced by clumsy thrashing. Trout in fast water zones learn to watch for these struggling invertebrates that drift past holding lies, offering easy interception opportunities without requiring energy-expensive chases.
