This highly realistic fly mimics the vibrant red larvae of midges, commonly known as bloodworms—an essential food source for freshwater fish.
Tying the Perfect Bloodworm Fly
Tied on hooks from size 18 to 10, this pattern uses red or maroon thread, floss, or synthetic materials to replicate the natural hue. Fine wire or contrasting thread ribs add segmentation for durability, while beads or dubbed material create a lifelike head.
Why It Works
Designed to imitate midge larvae, the Bloodworm Fly’s slender shape and vivid color make it irresistible to trout and other species that feed on these aquatic insects.
Best Fishing Spots
Effective in diverse freshwater environments, the Bloodworm Fly excels in streams, rivers, and lakes where midge larvae thrive.
