Longlous poems

This insect looks particularly like a cockroach, but it is more valuable than a cockroach. First, if it flies into the water, it will feed on some microorganisms in the water. Then if it flies to land, that is, fields or trees, it will feed on some small insects. But one thing is that it will eat some vegetables and fruits in the field, so it is also called a pest in crops by human beings. But on the one hand, this insect is edible, its back is black, edible and has high nutritional value. You can imagine how valuable this insect is if you put a string on a night market stall and ask for 10 yuan.

In fact, people also have a bullish name, called: lice. The water quality requirements of water lice are very high, and it is difficult for water lice to appear in some polluted waters. Because of its excellent nourishing performance, the water louse is also called water ginseng, which is used to make soup, stir-fry, soak wine and make various dishes.

Although lice are harmful to fisheries and have an impact on water ecology, as a part of the biological chain, they actually exist for a reason. They can purify water and eat some rotten sites, plankton and so on.

Ticks are mainly carnivorous, and can also be used as phytophagous and saprophytic bait, especially good at catching small organisms, organic matter and aquatic plants in water. It has a great influence on the larvae of small fish, shrimp and frog in the pond. Although it can eat some rotten food to purify the water quality, it is still very harmful to the cultured ponds and poses a strong threat to young creatures.
