To comprehensively reveal pollination mutualisms between Colocasiomyia flies and Araceae plants from a point of evolutionary view, we studied taxonomy, phylogeny, biogeography and reproductive ecology of the genus Colocasiomyia and flowering/pollination ecology of their host plants. As a result, it has been revealed that there is a large diversity in this pollination mutualism system, and that to promote pollination host plants attract and guide pollinator flies by emitting heat and odor and providing food rewards timely from proper regions of inflorescence through flowering process.
