The life table of Batrachedra amydraula Meyer (Lep.: Batrachedridae) was studied at 30±1˚C, 60±5% RH and 24 hrs darkness, in the laboratory. The raw data was analyzed based on the age-stage two-sex life table, in order to take both sexes and the variable developmental rate among individuals and between sexes into consideration. Mean development times of immature stages were 51.91±1.61 and 53.3±2.3 for males and females, respectively. The intrinsic rate of increase (rm), the finite rate of increase (λ), the net reproduction rate (R0), the growth reproduction rate (GRR) and the mean generation time (T) of B. amydraula were 0.039 d-1, 1.0398 d-1, 9.39 offspring, 59.68 offspring and 57.37 day respectively
