Animal name: Earth sweeper-

There is a mysterious insect, burly and covered with shining armor. As early as about 6000 years ago, it was discovered by ancient Egyptians. People thought that this mighty beetle was made into a very delicate ball bigger than its own body by the will of God. Do you know what this is?

This black beetle is dung beetles. They have hard typical wing sheaths and special petaloid antennae. But dung beetles are not like bees-they give people sweet honey and pollen; Nor did it show gorgeous dancing and light posture like a butterfly. It only feeds on dirt and garbage, and takes feces as a hole, so it also has an elegant name-"Dung beetle". They are humble, mean, dirty and hated by many people, but I will praise them because they are the scavengers of the earth!

First of all, the earth sweeper

1, dung beetles rolls the dung ball.

Dung beetles are very interesting If they find human or animal feces, they are made into dung balls. When making dung balls, they first pile the dung together with their heads, and then beat the dung into a ball with their front feet. At this time, "husband and wife" work together, one pulls in front and the other pushes behind, so that the dung ball rolls forward. After rolling to the predetermined place, the female dung beetle digs a hole in the dung ball with her head and feet, lays her eggs in it, then pushes the ball into the hole dug in advance and buries it with soil. Hatched larvae feed on dung balls until they become pupae in the soil. This is why dung beetles roll dung balls, which can not only make them thrive, but also prevent environmental pollution.

2. China dung beetles take root in Australia.

Dung beetles, though so humble, has a great effect. Without it, it is really a disaster. For example, Australia, which has always been famous for its animal husbandry, has raised tens of millions of cows, many of which discharge hundreds of millions of tons of feces every day, covering more than 400,000 hectares of grassland. At the same time, cow dung also breeds maggots, and grasslands are also degraded in a large area, causing serious environmental pollution. This incident is a headache for Australians. Later, they introduced dung beetles from China and asked them to help "clean up", so that grasslands could be revived and animal husbandry could continue to develop.

Are there no dung beetles in Australia? Yes, but the dung beetles there don't eat cow dung, but only kangaroo dung. It seems that dung beetles in different places have different habits.

3. Dung beetles treat urban garbage

At present, municipal waste is often disposed by burning and burying, which not only pollutes the environment, but also consumes manpower and material resources. I think if we train some dung beetles to clean up the garbage, especially the garbage that can't be recycled and the sundries that people don't want to get close to, then the problem of garbage pollution will be solved. In addition to cleaning up garbage, we can also use the characteristics of dung beetles to change their genes with some biotechnology, so that they can not only roll dung balls, but also roll high-radiation objects that people can't touch, which is not only cheap, but also beneficial.

Second, the weatherman.

In the twilight around the evening, we can often see pairs of dung beetles busy in the fields, buzzing around, which indicates that the next day will be a sunny day; If you see a dung beetles running around mindlessly, it will be cloudy the next day. It can be seen that dung beetles are also keen weather forecasters.

Small insects are mysterious, but we haven't studied dung beetles yet. ...

Yesterday, dung beetles was born in a dunghill, unknown; Today, it attracts much attention and has extraordinary value; Tomorrow, we will use the power of science to turn fantasy into reality and add a more brilliant stroke to the biological world.
