The leafy spruge hawk moth H.euphorbiae is monophagous insect feed on different species of the genus Euphorbia. The biology of H. euphorbiae was studied in detail during May to November under laboratory conditions. The development of egg, larva, pre-pupa and pupal periods occupied 9.42±1.65, 20.31±2.08, 2.67±0.37 and 57.10±5.97 days, respectively. Total life cycle was 89.5±10.1.The sex of H. euphorbiae can be determined during pupal stage, in the male there are two small points at the fifth segment, while in females there's a line at the same position. Adults became active in the night .All mating observed among caged adults occurred at night. The longevity of the female ranged from 11-16 days with an average of 13.86± 1.73,while in case of male it was 8-11 days with an average of 10.55±1.00
