Function of the "Warning Coloration" in Larvae of a Diurnal Moth, Pryeria sinica MOORE (Lepidoptera : Zygaenidae)

Abstract

P. sinica larvae were given to the lacertid lizards Takydromus tachydromoides to determine the protective effect of the conspicuous coloration of the larvae. Pryeria larva was protected perfectly from attacks by the lizards because of peculiar-smelling fluid secreted on the body surface of the larva. Yellow and black body color of Pryeria larva had a meaning as the warning coloration at least for a lizard. Characteristics of predatory behavior in Takydromus were also analyzed and not only visual cues but also other factor (s) played important role in the process of recognition and choice of preys. Such a system may be considerably different from that of birds.
