Morphological Characteristics and Developmental Stages of Daphnis nerii (Oleander Hawk-Moth)

Abstract

Abstract The life cycle of Daphnis nerii, commonly known as the Oleander Hawk-Moth, was investigated through laboratory rearing in 2022. The study focused on observing the morphology and duration of different life stages, including the egg, larva, pupa, and adult. The life cycle of D. nerii consisted of five instars. Eggs hatched after 4-5 days, and the larval development involved first instar (4-5 days), second instar (on day 11), third instar, fourth instar and fifth instar (between day 15 and 19) reaching a full length of 90-130mm. The pupal stage lasted for 20-40 days. This study provides valuable insights into the developmental stages and duration of D. nerii, contributing to our understanding of its life history and biology.
