Morphology and Biology of Two Butterfly Species, Graphium sarpedon Linnaeus, 1758 and Graphium agamemnon Linnaeus, 1758 on their Respective Host Plants

Two butterfly species, Graphium sarpedon Linnaeus, 1758 and Graphium agamemnon Linnaeus, 1758 belonging to the family Papilionidae were studied both on the morphological and biological aspects during the study period from May 2008 to December 2009. South Okkalapa Township, Yangon Division was chosen as the study area where the host plants for the two studied species were abundant. Cinnamomum macrocarpum, C. tamala and C. obtusifolium were the host plants for G. sarpedon whereas Polyalthia longifolia and P. pandurata were the host plants for G. agamemnon. Morphological characters and the life cycle of the two studied butterfly species were depicted in comparative point of view supported by scaled photographs. Duration of the developmental stages from the eggs up to the emergence of the adults in these two species was also mentioned. Behavioural patterns of both species were also described providing with photographs.
