At various phases of their lives, Ariadne merione (the common castor butterfly) and Achaea janata (Castor semilooper moth) were studied (Egg, Larva, Pupa, Adult). The study was performed in the year 2019. Both kinds of lepidopterans were recovered at the egg and larval stages from Ricinus communis (the castor plant). The eggs were laid in a cluster beneath the host plant's leaves. During the investigation, the captured larva was fed fresh castor leaves, and the various stages of its life cycle (egg, larva, pupa, and adult) were seen, recognized, and reported. The goal of the study was to monitor the dramatic changes in the common castor butterfly and castor Semilooper moth's life cycles, as well as to investigate the entire description of the adults, eggs, larvae, and pupae.Ariadne merione blooms from March to May, whereas Achaea janata blooms from August to September. The castor Semilooper moth takes 48 to 50 days to complete its life cycle from egg to adult, while the common castor butterfly took 22-32 days.
