"No one will understand these valuable cleaners, such as dung eaters and insect buriers; But as we all know, Culex pipiens is bloodthirsty, irritable and aggressive. It is a wasp with poisonous needles and a bad ant with many evils. In the villages in the south, ants gradually erode the beams of houses, making them in danger, just as they are eating figs.

This passage comes from the chapter "Cricket's Cave and Egg" in Entomology.

Looking back at human nature with "insect nature" is a major artistic feature of insect stories.

Connotation:

The dung-eating insects and buried insects that have been quietly paid have never been valued and treated with courtesy, while butchers such as ants have always been cared for and praised.

This is like "doing good things in obscurity, but being praised for evil deeds" in the human world.

Entomology reflects on human life with the nature of insects, thinking about human living conditions, life attitudes, values and so on. And wise philosophical thinking is also on the paper.
