  Different developmental stages of Coccinella septumpunctata was observed that the egg, larval, pre-pupal and adult stages occupied more duration in first generation as compared to second, total larval period 16±1.73 days and pupal period, 7.5±0.87 days was more in first generation in contrast to second 13.5±0.87 days and 6.5±0.87 days, respectively. However, similar was the trend with respect to longevity of males and females.Adult stage of Coccinella septumpunctata consumed more aphids in both generations as compared to larval. Nevertheless, when a comparison was made, between larval instars, it was observed that older larvae consume more number of aphids/day than younger ones.
