Bloodworm (Midge Fly Larva)

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).
