LeechMicro Sour Apple Leech
The Micro Sour Apple Leech is a compact olive leech pattern from DRAGONtail Tenkara designed for finesse presentations with tenkara and light fly rods. Featuring an apple-green tungsten bead and olive pine squirrel zonker, this pattern offers excellent movement in a small package. The dubbing loop collar technique creates a dense but mobile profile that fish find irresistible in clear water.

Overview
This DRAGONtail Tenkara pattern by Brent Auger demonstrates the effectiveness of olive leech patterns, which often outperform the more common black varieties. The apple-colored bead is believed to enhance effectiveness, serving as a subtle attractor. The dubbing loop collar technique uses fibers pulled from the pine squirrel zonker strip rather than ostrich herl, creating excellent movement while being easier to work with and more durable.
Materials
Hook: Moonlit TOGATTA ML211 Premium Barbless Hook, #14
Thread: Semperfli Classic Waxed Thread 12/0 (70 Denier), medium olive
Bead: Moonlit Slotted Tungsten Bead, 3.0mm, light olive (apple)
Body/Collar: Moonlit Pine Squirrel Zonker Strip, olive, 1/16" (2mm)
Behavior & Presentation
Natural Behavior: Bright olive leeches swim actively near bottom structure, their high-contrast coloration triggering territorial responses. The vibrant apple-green color signals different leech species that trout recognize as distinct prey items.
Where Trout Eat It: Near bottom in lakes and slow pools fish target bright leeches, while mid-column feeding occurs during active hunting. Clear water allows maximum visibility of the distinctive coloration.
How to Fish It: Dead drift through holding water or add slight twitches to activate pine squirrel fibers. The small size and natural materials allow confident presentations where fish inspect offerings closely.
Best Water: Target weed edges where bright colors matter, drop-offs concentrating predatory fish, and structure where territorial behavior is strongest.
Strike Type: Aggressive strikes as fish react to the bright moving profile standing out against natural backgrounds.
Fishing Strategy
Rigging Suggestions: Fish on tenkara line or 10-12 foot leader with 5X-6X fluorocarbon tippet. The tungsten bead provides enough weight for most presentations without additional split shot. Can be fished under a small indicator in lake.
Seasonal Timing: effectiveness in both rivers and lakes. The compact size makes it particularly useful during periods of heavy fishing pressure when fish become wary of larger flies.
Pro Tips: The 3.0mm tungsten bead provides adequate sink rates for reaching trout holding zones in moderate depth water. Use smaller beads for skinnier water, larger beads for faster sink rates.
Entomology
Leeches undulate through the water column with characteristic serpentine swimming motions, periodically pausing to drift or slowly sink. Trout target these soft-bodied invertebrates because they provide substantial protein in a single gulp with no hard parts to avoid, making them an efficient food source especially during seasonal migrations to shallow water.
