| Outline of Final Research Achievements |
An excellent example of mimicry is the flower-mimicry of the orchid mantis Hymenopus coronatus with pink and white coloration and petal-like legs. Biochemical analyses indicated that the reduced form of xanthommatin contributes to the pink body coloration. However, xanthommatin is distributed widely among insects and it still remains unclear how the common pigment form the unique pink coloration of the orchid mantis. In this study, we identified three different types of xanthommatin isoforms and found that their composition varies in mantises having different body colors. We also found that pigment granules in the orchid mantis have unique ultra-structures, which may contribute to the unique pink coloration of the mantis.
