The biology of Coccinella septempunctata was studied under laboratory conditions on cabbage aphid, Brevicoryne brassicae. The results revealed that the duration of egg, larval, pupal, adult (male) and adult (female) life stages were found to be 2.50 ± 0.51, 17.50 ± 2.52, 3.80 ± 1.09, 28.00 ± 5.04 and 37.27 ± 3.21 days, respectively. The total number of aphids consumed by larval I, II, III and IV instars was found to be 6.76 ± 1.05, 14.36 ± 1.32, 24.80 ± 3.82 and 42.53 ± 2.17 aphids, respectively. The female adults on an average consumed significantly higher number of aphids (2314.04) than male adults (1797.63)
