Abstract

Oviposition by female butterflies plays a major role in initiating the life cycle of its offspring. In this study, field oviposition behavior and early life stages of three common butterfly species were studied, documented and illustrated at the Institute for Tropical Biology and Conservation, Universiti Malaysia Sabah. Individual females were observed and their activities of oviposition behaviour were recorded. Larval developmental of the three selected butterfly species namely, Papilio polytes (Papilionidae), Graphium sarpedon (Papilionidae), and Elymnias panther (Nymphalidae) were recorded and described in detail. Observation on the larval development was done daily and morphological changes were recorded. Females for the three selected butterfly species were present and occasionally seen at the Institute for Tropical Biology and Conservation starting as early as 0900 to 1130 hours. No oviposition behaviour was sighted after 1200. Females tend to chose their oviposit site which contribute higher level of survivorship of its egg. Eggs which were deposited at the lower side of the leaf have greater opportunity of reaching at least until the pupal stage. A total of three host plant species were identified: for P. polytes, Citrus minocarpa (Rutaceae), G. sarpedon, Cinnamomum zeylanicum (Lauraceae) and E. panthera, Chrysalidocarpus lutescens (Arecaceae). Total days for each of the butterfly species to complete the stage from egg until reaching adult were 36.S3±3.S0 days for P. polytes, 28.S4±3.33 days for G. sarpedon and 43.07±4.51 days E. panthera. Based on this study, the Institute for Tropical Biology has a great potential in establishing a butterfly research rearing site. The Borneensis holds a great deal of specimens but the record for its life history according to its localities have yet to be studied in detail. Such studies will not only contribute to the conservation management of butterfly species but it will also contribute greatly in the pest management.
