  • Abstract The Batesian mimicry involving Papilionidae is often sexually dimorphic, female-limited, and polymorphic. According to the case studies based on the mimicry relationships exhibited by several North American, African and Asian Papilio species, it has been realized that the occurrence of mimetic female form correlates with relative abundance of the model. Papilio memnon is a fairly common swallowtail butterfly ranging throughout India, Sundaland and S.E. Palaeartic region. The female is extremely polymorphic with at least 17 forms being recognized and many of them often regarded perfectly mimetic with several troidine butterfly models occurring in the same distribution range. However, neither the occurrence of the so-called mimicry of this species has been questioned nor the effectiveness of the putative aposematic colouration has been tested using modern methods. Here we present a result based on an analysis of geographical correlations between possible mimetic female forms and their possible model(s) from numerous museum specimens and animal behavior experiment. The results show that: (1) There might be no prefect mimicry occurring between female P. memnon and their potential models; (2) the accurate mimicry involving the P. memnon complex may only be presented by P. lampsacus and P. oenomaus and their models; (3) the mimetic colouration (either perfect or imperfect) may have independently evolved for several times; (4) the presence or absence of hindwing tail or some specific maculation does not necessarily contribute in enhancing resemblance between P. memnon and the model(s); and (5) some elements of interactive regulation, it will affect the judgment of predator.
