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.Je是一个一直很幸运的女孩，而Not却很不幸。 这两个晚上，彼此相遇，倒霉。 Je对这个解决方案感到不满，因此她打算找回自己的运气。Dry cleaning resistanceThe second step is to transform the Upload constructor and create an instance object for each state subclass in the constructor:玄武将军跟夫婿逛灯市。他其实根本不确定对方有没有望远镜一类的仪器，也许根本就看不到这一出空城计，如果对方看不到我们，直接开炮，我们是不是就死了。
