Butterfly is a fully metabolized insect, its life cycle has four different stages: egg stage (embryonic stage) (larval stage) (pupa stage) ( stage (the three development stages after ual stage are collectively referred to as the four development stages after embryo development). From the perspective of morphology, there is nothing in common. Therefore, we must observe systematically or continuously It is a species of four stages of development, the four stages of development cycle and start, forming a life cycle, also known as a generation of butterflies to complete a life cycle, short, a few days (such as Pieris rapae in recent three years (for example, the number of generations in a year of Panas in Northeast China, often due to the Babesia species have different generations a year (such as Chinese Tiger swallow tail) there are many generations (such as Chinese Tiger swallow tail) The generation of Pieris rapae is often different from the level of temperature.
In Heilongjiang Province, they only have generations in Guangdong Province in a year, but they can be named as several generations at most. From the beginning of the year to the end of the year, they are called the first generation, the second generation, etc. In addition, there are also seasonal and named generations.
For example, the emergence of s in spring is called the spring generation, and the emergence in summer is called the summer generation.
