Bloodworm (Larva of Non-biting Midge)

Natural Habitat

Freshwater sediments, soft mud in lakes, ponds, and slow-moving rivers, or moist household environments.

Diet & Feeding

Organic debris, algae, and microscopic organisms found in the sediment.

Behavior Patterns

They are known for their bright red color due to hemoglobin, which allows them to survive in low-oxygen environments. They spend most of their life in the larval stage submerged in mud.

Risks & Benefits
