Abstract : Biology and morphometric studies of mango leaf webber, O. euadrusalis, were undertaken under laboratory conditions (14±2 and 25±2°C, 80±5% RH). The incubation period was 6.8 days. There were 7 distinct larval instars and the duration of the first to seventh instars was 4.3, 4.7, 5.7, 6.5, 6.6, 7.6 and 8.6 days, respectively. The female laid 58 eggs within 4.8 days. The female and male lived for 5.3 and 7.6 days, respectively. The total life cycle of male and female was completed in 81.7 and 84.0 days, respectively.
