The female moths of this species exhibit a longevity of 5.8 ± 0.10 days, while the male moths live for 3.9±0.15 days. The egg, larval, and pupal period of N. geometralis was 3.35 +0.11, 10.65 +0.20, and 6.65 ± 0.11 days, respectively. The adults recorded longevity of 6.7±0.15 and 4.8±0.13 days, respectively, for female and male moths.
