What are Free Swimming Blood Worms?

Free swimming blood worms are the larvae of midge flies. These worms are small and thin, typically measuring less than an inch in length. They are bright red in color due to the presence of hemoglobin, which allows them to survive in oxygen-poor environments such as muddy lake bottoms.

Why are Free Swimming Blood Worms Effective for Fly Fishing?

Free swimming blood worms are a favorite food of many fish species, particularly trout. They are especially effective during the winter months when other food sources may be scarce. Fish tend to feed on free swimming blood worms when they are actively swimming and moving through the water.

How to Fish with Free Swimming Blood Worms?

When fishing with free swimming blood worms, it is important to use the right equipment. A light rod and reel setup is ideal, as these worms are very light and delicate. Use a small hook, size 16-20, and attach the worm using a thread or tippet.

When casting, it is important to make sure the worm is drifting naturally in the water. Use a slow, steady retrieve to imitate the movement of the worm. The key is to make the worm look as natural as possible. This means avoiding any sudden movements or jerks that could scare away the fish.

Where to Find Free Swimming Blood Worms

Free swimming blood worms can be found in a variety of freshwater environments, including lakes, ponds, and slow-moving rivers. They are most commonly found in muddy lake bottoms, where they can burrow and survive in low-oxygen environments. If you are having trouble finding free swimming blood worms, consider using a seining net to collect them from the lake bottom.

In conclusion, free swimming blood worms are a highly effective bait for fly fishing. Their bright red color and natural movement make them irresistible to many fish species, particularly trout. By using the right equipment and techniques, you can increase your chances of catching more fish on your next fly fishing trip.
