Abstract: Present study was performed to study ecology of Chironomus larvae found in the Udaipur region. Observation of habitat, feeding habits and their role as bioindicators in ecological monitoring was done. The pH, turbidity, temperature, chloride content, dissolved oxygen, COD and BOD were found 6.9, 28, 17 °C, 221 mg/L, 343 mg/L, 18 mg/L, 4 mg/L and 75 mg/L respectively. Their Shannon diversity index was measured is H`= 1.21. Their grazing and detritivorous feeding habits were shown by their gut analysis.
