Bloodworm (Midge Larva)

Found in the soft sediment of stagnant or slow-moving freshwater bodies like ponds, lakes, and marshes.

Feed on organic detritus, algae, and microorganisms found in the sediment.

They live in silken tubes within the mud; their red color comes from hemoglobin which allows them to survive in low-oxygen environments.

They are harmless to humans and are a vital food source for fish and waterfowl, though large swarms of adult midges can be a nuisance.
