Mirage Micro Leech (M & M Leech)

The Mirage Micro Leech (M & M Leech) designed by Phil Rowley is an effective stillwater pattern that combines the flash of Mirage Opal Mylar with the subtle movement of schlappen marabou and ostrich herl. This pattern creates a translucent, flashy profile that mimics small leeches and triggers strikes from cruising trout in lakes and ponds.

Behavior & presentation

Natural Behavior
Tiny leeches swim with subtle undulating motions near bottom structure, their small size making them appear as easy, low-risk meals. They pulse rhythmically while resting, creating just enough movement to attract attention.
Where Trout Eat It
Near bottom structure in lakes and slow pools, occasionally mid-column during swimming phases.
How to Fish It
Slow retrieves with extended pauses, allowing the small profile to pulse naturally during stops.
Best Water
Target weed edges where small leeches are abundant, shoals with varied substrate, and drop-offs that provide depth transitions.
Strike Type
Firm takes as fish strike confidently at the small, vulnerable profile that requires minimal energy to consume.

Fishing strategy

Rigging Suggestions
Fish on 12-15 foot leader with 5X-6X fluorocarbon tippet under a sensitive strike indicator. The bead provides adequate weight for proper presentation at various depths.
Seasonal Timing
effectiveness in lake environments. Particularly effective during periods when trout are actively feeding on small leeches.
Pro Tips
The Mirage Opal Mylar creates iridescent flash visible to fish at distance. The ostrich hackle collar adds subtle movement and helps slow the sink rate slightly for a more natural descent.

Entomology

Small leeches exhibit quick, panicked swimming when exposed in open water, their translucent bodies catching light as they attempt to reach cover. Fish exploit these vulnerable moments because smaller leeches lack the defensive mucus coating of adults, making them more palatable and easier to digest.
