The research was conducted to investigate the feeding potential, oviposition, larval and pupal stages of Lady Bird Beetle (Coccinella septempunctata) on Crape Myrtle Aphid (Tinocallis kahawaluokalani). The research was conducted at the department of Entomology Laboratory, PMAS Arid Agriculture University Rawalpindi. It was observed that feeding potential of the 1st, 2nd, 3rd and 4th larval instar of C. septempunctata was affected significantly (P<0.05) by host density. The feeding potential of C. septempunctata were observed, the offered aphids were 17, 20, 20 and 30. The average aphids consumed were 9±0.10, 12±0.80, 12.4±1.1 and 23±1.4 by the 1st, 2nd, 3rd and 4th instar of C. septempunctata grubs, respectively. Feeding potential increased while the host density increased significantly 9±0.10, 12±0.80, 12.4±1.1 and 23±1.4. The C. septempunctata Consumption percentage were also increased 52.9±0.60, 60±4.00, 62.1±5.81 and 85.4±1.9 on all the grub instars, respectively. The C. septempunctata life table stages were observed i.e., oviposition period, total number of eggs laid, total number of grubs emerged, eggs incubation period and hatchability percentage. The average eggs layed was 88.6, average number of grubs emerged was 82.8, average eggs incubation period was 3.6 days and the total hatching percentage was 86.2%. The mean larval period completion was 13.5 days and pupal stages completion was 5.2 days respectively.
