LeechPolar Chenille Leech
The Polar Chenille Leech is a guide box staple from Kyle McCallum, designed for the San Juan River and beyond. This simple yet effective pattern combines a tungsten drop bead with polar chenille to create a jigging action and subtle translucency that trout find irresistible. The straightforward construction makes it an excellent choice for tyers of all skill levels.

Overview
This AboutTrout pattern by guide Kyle McCallum showcases the effectiveness of simple materials combined thoughtfully. The drop tungsten bead creates a jigging motion that brings the fly to life while the polar chenille provides translucency and subtle movement. The jig hook design keeps the point riding up to reduce snags on the rocky bottom of tailwater rivers like the San Juan.

Fishing Tips
Season
Year-round effectiveness with particular success on tailwater fisheries where trout feed on leeches throughout the seasons. The dark profile works well in both clear and slightly off-colored water.
Presentation
Fish using euro nymphing techniques or under an indicator. The drop bead creates a jigging action on the pause that triggers strikes. Allow the fly to sink to depth before beginning a slow, twitching retrieve.
When to Use
Select this pattern as a reliable searching fly on tailwater rivers or when targeting trout that are keyed in on leeches. Works well as a point fly in a multi-fly euro rig.
Water Type
Designed primarily for moving water, especially tailwater fisheries like the San Juan River. Effective in runs, pools, and along structure where trout hold waiting to ambush prey.
Rigging Suggestions
Fish on a euro nymphing rig with 5X-6X fluorocarbon tippet. The 3.5mm tungsten drop bead provides adequate weight for most presentations. Works well paired with smaller nymphs as droppers.
Visibility & Floatation
The silver drop bead adds flash while providing weight for the jigging action. The black polar chenille creates a translucent profile that mimics natural leeches while the marabou tail undulates enticingly with each movement.
