The biology and feeding potential of Sphaerophoria javana Wied, were studied in the laboratory at 27.9±1.1° C and 85.7±5.2 percent relative humidity, on Aphis craccivora Koch, a common pest of Dolichos lablab L. The egg, larval and pupal stages occupied 1.96±0.07, 6.30±0.22 and 5.38±0.04 days, respectively. The total life cycle was completed in 14.02±0.2 days. The per day consumption of first, second and third instar larvae was 12.7±2.2, 69,4±7.4 and 112.2±7.7 aphids, respectively.
