Bloodworm are one of the stages of chironomidae. The Bloodworm flies are blood red in color and found at the bottom of lakes and rivers great for Rainbow & Brown Trout.
Midges start life as a bloodworm and live in the soft mud found in most still waters and some silted muddy rivers. They get their color from the oxygen and hemoglobin held within their bodies. Many other freshwater species love these buzzers.
