　　The Traveller's Palm

　　The Traveller's Palm produces large quantities of sweet nectar to attract pollinators. But the Madagascar black lemur (狐猴), a monkey-like mammal, is one of the few animals strong enough to open the flower. When it pulls the flower apart to drink the nectar, the pollen sticks to its head. Looking for more nectar, the lemur moves on to another palm, and the pollen stuck to its fur now sticks onto the new flower. So the Traveller's Palm is pollinated, and the lemur satisfies its sweet tooth.

　　The Ophrys Orchid

　　Ophrys is an orchid with a flower that looks, and even smells like, a certain kind of female wasp. When the male wasps come out of their pupae (蛹), they are attracted by the smell and try to mate with the flower. In doing so, they collect the pollen which is then moved to another Ophrys flower when he tries to mate with that flower. When the orchid flowers are dying, the female wasps then come out of their pupae and visit the flowers to collect a chemical, the same one to which the males were attracted earlier. The male wasps, attracted by the smell, then mate with the real females.
