The eggs of butterfly, Pieris brassicaewere collected from cabbage field during February- March 2018. The collected individuals were transferred into insect collection paper packs and were brought to the laboratory for further study. The caterpillars feed fresh leaves of cabbage. The pupal stage on host plants, adults emerge in mid-spring and eggs lying in bunch on the undersides of outer of leaves. The incubation period of eggs was 4.80±0.45 days while 26-27 days were taken by larvae. The last instar larvae were found to change into pupae by spinning cocoon. The total period of pupae was 7.91±0.80 days. The newly emerged adult were separated and identified. The wing span of male and female were 60 mm and 70mm, respectively. These finding could be used in management of P. brassicae.
