In some swallowtail belonging to genus Papilio, two types of pupae, viz., green type and brown type, can be distinguished. It was found in the laboratory as well as by field observations that the pupae which have pupated on green twigs of food plant, Poncirus trifoliata L., are always of the green type while those which pupated on dead branches are of the brown type. The same correlation also exists in the pupae pupated in the darkness. Therefore, the colour of the surroundings connot be considered as a principal factor, contrary to as has hitherto been believed to be the sole agent. The authors also examined with failure the possibility that selection of the sites for pupation and the type of the pupae might be determined genetically. The result indicates that although the pupal types are determined by some unknown environmental factors at the time of pupation, the visual perception of the colours is not sine qua non.
