Honeybees are very industrious beneficial insects, because they always work day and night in order to obtain food, not only to collect honey during the day and to make honey at night, but also to complete the pollination process of fruit trees. it is a typical representative of pollination insects and is the main pollen transmission medium such as crops, fruits and vegetables, traditional Chinese medicine plants, forages and so on.

Mantis, also known as knife mantis, is a slender-looking carnivorous insect. They also have a very elegant name-prayer insects, because the forearms of the mantis are raised as if they were praying. Mantis is distributed all over the world, and there are many kinds of mantis. It is a very powerful natural enemy of agricultural pests.
Mantis likes places with light and can change its life cycle in a year, and its age is mainly affected by the amount of food and the environment.
Nowadays, wild mantis is relatively rare, because of the widespread use of pesticides, there are two main ways of artificial breeding mantis, one is egg sac preservation and outdoor cage breeding.
So, what does the mantis eat? They usually take cicadas, butterflies and locusts as food, so we should not catch them back casually, because they are good helpers for crops.
3. Dragonfly
Dragonflies are beneficial insects that feed on mosquitoes, flies, moths and so on. When I was a child, I liked to watch dragonflies very much. I often looked at them quietly, and sometimes I would catch them and look at them before releasing them. Of course, this is not right. Dragonfly flying low is also a symbol of weather, especially when it is going to rain heavily, dragonfly always flies very low. Dragonflies are relatively large, with two pairs of wings, showing a reticulation, their abdomen is flat, and their horns are very thin but with hooks, so they are good helpers for catching insects.
There are many kinds of dragonflies, and there are also many eyes. In science, there are also some scientific and technological products that use dragonfly eyes. In addition, dragonfly also has a certain medicinal value, can play an aphrodisiac, antisperm effect.
The above are the answers to the questions about what beneficial insects have and what to eat respectively. I hope it will be helpful to you.
