The Coevolution of Flowering Plants and Their Insect Pollinators
Quick fact
The orchid family (Orchidaceae) includes species that have evolved incredibly specific relationships with their pollinators, such as the bucket orchid (Coryanthes), which traps male euglossine bees in a liquid-filled bucket and forces them to crawl out through a narrow passage that glues pollen to their backs.
Why this is interesting
You've probably noticed that bees are drawn to certain flowers and not others. But have you ever wondered why flowers are so colorful and bees have such strange body parts? The answer is a dance of evolution that has been going on for over 100 million years.
