Bloodworm (Larva of Non-biting Midge)

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

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

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.

Harmless to humans as they do not bite; they serve as a vital food source for fish and help in the recycling of organic matter in aquatic ecosystems.
