See this bug in the Encyclopedia

Natural Habitat

Found in the sediment of freshwater bodies such as ponds, lakes, and slow-moving streams. They are often found in low-oxygen environments.

Diet & Feeding

They feed on organic debris, algae, and microscopic organisms found in bottom sediments.

Behavior Patterns

They live in tubes made of silk and sediment. The red color comes from hemoglobin, which allows them to absorb oxygen in stagnant water. They eventually pupate and emerge as non-biting midges.

Risks & Benefits

They are harmless to humans and do not bite. They are an essential food source for fish and birds and help monitor water quality, though high numbers can indicate organic pollution.
