LeechMayer's Mini Leech
Mayer's Mini Leech is a compact, heavily weighted leech pattern developed by Colorado guide Landon Mayer. The slim profile and tungsten bead allow it to sink quickly into the strike zone, making it ideal for targeting trout in deep runs and pools. Its simple construction and effectiveness have made it a modern classic.

Overview
Developed by Landon Mayer, a renowned Colorado fly fishing guide known for his innovative approach to targeting large trout. The Mini Leech was designed specifically for sight-fishing to selective trout in clear western waters. The pattern's compact size and quick sink rate make it particularly effective when larger leech patterns are refused. Available commercially through Umpqua Feather Merchants.

Fishing Tips
Season
Effective year-round as leeches are present in most trout waters throughout the seasons. Particularly productive in spring when leeches become more active after winter dormancy, and in fall during pre-spawn feeding periods.
Presentation
Use a dead drift presentation in moving water, allowing the fly to tumble naturally along the bottom. In stillwater, employ a slow hand-twist retrieve with frequent pauses. The heavy bead gets the fly down quickly, so adjust leader length accordingly.
When to Use
Excellent choice when fish are holding deep or when larger patterns are being refused. Works well as a searching pattern in new water. Particularly effective when sight-fishing to visible trout, as the compact profile is less likely to spook wary fish.
Water Type
Designed for clear western rivers and streams but equally effective in stillwater. Works well in tailwaters, freestone streams, and spring creeks. The slim profile performs excellently in slow, clear pools where fish can inspect offerings closely.
Rigging Suggestions
Fish on 9-12 foot leader with 4X-5X fluorocarbon tippet. Excellent as a point fly in a two-nymph euro rig or under an indicator. In stillwater, use as part of a chironomid-style presentation with strike indicator set to depth.
Visibility & Floatation
Sinks rapidly due to the tungsten bead, reaching depths of 4-6 feet in seconds. The dark silhouette provides excellent visibility to fish from below. Pine squirrel fibers undulate enticingly with minimal movement, creating lifelike action even when stationary.
