Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.

There are also some plants pollinated by insects, which do not bring any benefits to insects, but attract their own pollinators in a similar way of deception. For example, Mei Lan is an example. It set a simple trap to make the drone think it would be a wonderful date. The drone was the first to fly out of the hive in spring, while the female was relatively late. Orchids take advantage of this. Their flowers look very much like female bees, making many drones stay here. Moreover, the flowers of Red Gate Orchid not only look like female bees, but also can emit similar smell to female bees. The hungry drone was easily cheated and tried to mate with the lip of the orchid, so that the drone would stick to two pollen blocks, which were small balls wrapped in pollen. At this time, the pollen would fall off and then stick to the drone. The drone had to leave frustrated after the mating failed. When it was fooled again and stayed on another eyebrow orchid, it helped eyebrow orchid to pollinate.
