Bloodworm (Midge Fly Larva)
Chironomidae (family)
- Order & Family
- Order: Diptera, Family: Chironomidae
- Size
- Typically 10 to 25 mm (0.4 to 1 inch) in length
Natural Habitat
Found primarily in aquatic environments like ponds, lakes, stagnant water, and water troughs, but sometimes seen on damp surfaces near water. They thrive in low-oxygen environments.
Diet & Feeding
Detritivores; they feed on organic debris, algae, and sediments found at the bottom of water bodies.
Behavior Patterns
These are the larval stage of non-biting midges. They wiggle in a figure-eight motion when swimming. Their red color comes from hemoglobin, which allows them to survive in oxygen-poor water.
Risks & Benefits
Benefits: Major food source for fish and other aquatic wildlife; distinct indicator of water quality. Risks: Generally harmless to humans (they do not bite), but can cause allergic reactions in sensitive individuals handling them (often used as fish food).
