Book excerpt: The non-biting chironomid midges (Family Chironomidae, Order Diptera) include numbers of species whose larvae develop in bodies of fresh water and which play an important role in the transmission of nutrients along the food chain. They consume organic matter and microorganisms from the bottoms of these bodies of water, and then are themselves eaten by fishes and arthropods. They do not usually cause damage or transmit diseases, and as a result have been neglected by entomological research. But their usefulness in indicating levels of pollution and water quality conditions makes them important objects of study.
