The biology of leaf webber and capsule borer, Antigastra catalaunalis was studied on sesame variety HT-2 under laboratory conditions during kharif, 2016. Eggs laid singly, conical in shape and white in colour with length and width varied from 0.35 - 0.45 mm and 0.18 - 0.25 mm, respectively. Incubation period varied from 2.32 to 2.42 days and viability of eggs varied from 73.34 - 90.00 percent. There were five larval instars and total larval period varied from 9.88 to 13.08 days. The pupal period lasted from 5.25 to 7.25 days. The average length and breadth of pupa was 7.29 ± 0.32 and 1.26 ± 0.29 mm. Percent adult emergence ranged from 70.00 to 85.00 with an average of 76.00 ± 6.51. Adults were stout and medium in size. The colour varied from light reddish brown to dark reddish brown. The females lived slightly longer than the males. The oviposition period ranged from 2.50 to 4.00 days and fecundity varied from 53.00 to 92.00. Average male to female ratio was 1.0 to 1.09.
