Three particular sites was chosen where matured plants of N. indicum were already present. The morphological and detectable behavioural aspects of fourth and fifth instar larvae, pupae and the emergence of adult out of its pupal stage were observed in the selected study site at temperature ranging from 26°C-28.7°C. This study presents a pilot approach towards ovipositional behaviour of adult E. core in choosing a suitable site for laying eggs in the natural environment by studying the height, coordinates, daily weather conditions and neighbouring environmental factors. In addition to the lifecycle, the current study also adds a note on the larval food relationship with N. indicum by focusing on the sequestrational power of larvae of E. core to the harmful cardiac glycosides present as a defense mechanism in the foliage of Indian Oleander.
