All social insects are like this.

1, lifelong social type. Ants and bees. There are many kinds of body differentiation in the group, sharing different functions.

2. Insect social types. Insects generally have four states: egg, larva, pupa and adult. Many insects do not live in groups. Some larvae live in groups, such as the larvae of the awning caterpillar, which gather together to harm a leaf, which is obviously gregarious. Scarabs mated in groups when they were first unearthed, and then they separated. The migratory insect armyworm is scattered in the pupa soil, and the unearthed adults gather together and move long distances with the airflow. Spider's eggs are in the oocysts. After hatching, they live in groups on the back of male spiders, and it takes some time to separate and disperse.

3. Environmental pressure type. Originally dispersed, when the environment is uncomfortable or the population density is too high, the unity or disunity of individuals changes and becomes a social form. For example, Locusta migratoria manilensis has scattered and gregarious forms.
