Invertebrates exhibit a remarkable diversity of anti-predatory strategies to ensure offspring survival. Oviposition behavior displayed by insects is one among such strategies. This study investigates the egg-laying behavior and life cycle of the Himalayan Large Yeoman butterfly (Cirrochroa aoris aoris), focusing on adaptations that mitigate predation risk. We conducted field studies within an urban forest fragment in Gangtok, Sikkim, eastern Himalaya. Large Yeoman utilized a variety of substrates for egg deposition, including leaves, branches, and stems. Interestingly, eggs were often deposited in a spatially dispersed pattern, potentially to minimize predation risk by reducing egg clumping. Notably, we also observed a unique behavior of egg deposition within unidentified webs, which may represent a novel anti-predatory adaptation requiring further investigation. Larvae fed exclusively on leaves of Gynocardia odorata, the first documented native larval host plant for this butterfly observed in the field. We delineated a complete metamorphosis cycle from egg to adult through rearing of six collected eggs. Large Yeoman completed metamorphosis within 29 to 32 days with an adult emergence rate of 33.33%. This study elucidates the effectiveness of the anti-predatory adaptations of Large Yeoman along with complete life cycle which significantly contributes in developing species-specific conservation strategies. Furthermore, extensive long-term study is essential to understand the detail anti-predatory activities and survival strategies of this butterfly.
