Background and Objective: One of the Nymphalidae butterfly species found in West Sumatra in Hypolimnas bolina. Currently, research on the artificial diet for the Nymphalidae butterfly is relatively rare in Padang, West Sumatra. The objectives of this study were to analyze the preferences of H. bolina larvae, duration of the immature stage and mortality of H. bolina in artificial diet treatment. Materials and Methods: Some biological aspects of H. bolina in corresponding to artificial diet and its effect were investigated in the laboratory. Results: The result showed that there was no significant difference in the frequency of visits of the larvae in the two diet treatments namely natural (Laportea interrupta leaves) and artificial diets (Sig = 0.289, p>0.05) but the duration of the visit of H. bolina larvae was significantly different (Sig = 0.000, p<0.05). The visit duration of the immature stage of H. bolina was significantly different, except the prepupa and pupal stage. There was no mortality of instar larvae and prepupa stage observed in both of the two-diet treatments. However, the mortality of pupae in an artificial diet was 4%. Of the total of 24 individual larvae fed with artificial diet, all of them successfully emerged, consisted of 12 males and 12 females but there was one male with abnormal wings. The average living period in the artificial diet of imago was 14.82 days for males and 16.77 days for a female. The average larval weight was no significant difference (Sig = 0.981, p>0.05) but the average pupal weight of the natural diet was slightly higher than the artificial diet. Conclusion: The formulation of an artificial diet is suitable for H. bolina larvae based on the results of immature mortality and adult emergences. Therefore, the formulation of an artificial diet is suitable for H. bolina with its composition almost similar to L. interrupta leaves (natural diet).
