Bloodworm (Chironomid Larva)

Found in the soft sediment of ponds, lakes, and slow-moving streams; often associated with low-oxygen environments.

They feed on organic debris, algae, and microscopic organisms in the sediment.

They exhibit a characteristic 'C' shape and use hemoglobin to absorb oxygen in stagnant water. They eventually metamorphose into non-biting midges.

They are a vital food source for fish and birds. They pose no risk to humans as they do not bite or sting, though high concentrations can indicate poor water quality.
