Aquatic Insects for Biomonitoring Freshwater Ecosystems: A Report

Aquatic insects may considered model organisms in analyzing the structure and function of the freshwater ecosystem because of their high abundance, high birth rate with short generation time, large biomass and rapid colonization of freshwater habitats. Aquatic insects are the major groups of arthropods that spend some parts of their life cycle in the water. Class Insect has many potential representatives that can be used as environmental bioindicators, among which are from the Coleoptera, Diptera, Lepidoptera, Hymenoptera. Water insects or aquatic beetles are biological indicator. The use of bioindicators is essential for environmental monitoring. This study deals with diversity and Importance of aquatic beetles in fresh water ecosystem and their role in water quality assessment as pollution indicator.
