A female fall armyworm, S. frugiperda laid 460 to 2424 pale greenish eggs in a mass mostly on the lower surface of maize leaves and covered with light brownish scales. The incubation period, larval period, pupal period and adult period of S. frugiperda were 2 to 5, 15 to 24, 8 to 13 and 6 to 15 days, respectively. The forewings of the male moth were greyish brown with a reniform indistinct spot and faintly outlined in black. The forewings of the female moth were ground brown with a mottled coloration of grey and brown markings, whereas the hindwing was silver-white. The developmental period and lifespan of S. frugiperda on maize were 28 to 40 and 32 to 59 days, respectively. The emergence of male and female moths from the pupa was 94.73 and 93.75 per cent, respectively.
