Overview
This Fly Fish Food pattern by Cheech demonstrates the effectiveness of Krystal Core Leech Yarn for creating lifelike movement in leech patterns. The yarn's built-in flash core adds subtle attraction while the soft fibers create undulating movement in the water. The gold bead provides weight and serves as an attractor point, while the dark mocha brown thread complements the olive body without creating harsh contrast.

Fishing Tips
Season
Year-round effectiveness with peak performance in spring and fall when leech activity is highest. The olive coloration matches natural leeches found in most waters throughout the seasons.
Presentation
Dead drift through likely holding water or use a slow, erratic strip retrieve. The leech yarn creates lifelike movement even with minimal angler input. Allow the fly to sink to the desired depth before beginning retrieval.
When to Use
Choose this pattern when targeting trout feeding on leeches in both moving water and stillwater. The olive coloration is particularly effective in waters with abundant vegetation.
Water Type
Versatile pattern effective in rivers, streams, lakes, and ponds. In moving water, fish through deep runs and pool tailouts. In stillwater, work along weed edges, drop-offs, and structure.
Rigging Suggestions
Fish on 9-12 foot leader with 4X-5X fluorocarbon tippet. The tungsten bead provides adequate weight for most presentations. Can be fished as point fly or as the anchor fly in a euro nymphing rig.
Visibility & Floatation
The 3.8mm tungsten bead provides rapid sink rates while the gold finish adds attraction. The olive leech yarn with krystal core creates subtle flash and a natural profile visible to fish from multiple angles.
