San Juan Wire Worm - Red

The San Juan Wire Worm – Red is a bold, highly visible subsurface fly that imitates aquatic worms and egg patterns with striking realism. Tied with a coated wire body in vibrant red, this fly offers a sleek, durable profile that cuts through the water and gets down quickly to where fish are feeding. It’s a favorite in off-color water or high runoff conditions when visibility is low and trout are seeking out protein-rich meals.

This pattern excels as an attractor or anchor fly in nymphing rigs, especially in tailwaters, freestone rivers, and during spring runoff or post-rain surges. The bright red color mimics aquatic worms dislodged from the riverbed and draws the attention of hungry trout, steelhead, or even carp.

To fish the San Juan Wire Worm – Red effectively, drift it under an indicator or with a euro nymph setup through seams, riffles, and deep channels. It works particularly well when paired with a more natural dropper fly like a midge or mayfly nymph.
