Blood Worm

The Blood Worm is a simple but highly effective imitation of midge larvae and aquatic worms found in nearly every trout stream. Its slim, wire-wrapped or tubing body creates a realistic translucent sheen that closely matches natural worm forms drifting near the bottom. This pattern excels as a dropper or anchor in nymph rigs, especially during winter and early spring when trout feed heavily on small worm and midge stages.

For added realism and durability, give the finished body a light coat of thin UV resin, but avoid curing it completely smooth—leaving slight texture mimics the natural segmentation of real midge larvae and helps the fly catch subtle light underwater.
