Listoists (lat. Chrysomelidae) is one of the largest types of families of hard-winged insects in which there are about 50 thousand species, and more potential even more.
Kinds
More recently, in 2020, in the course of research, complete monophilia of leaflet subfamily subfamers was revealed, so they all came from one common ancestor who died tens of thousands of years ago.
Of the main species in the classification, several subfamilies are currently distinguished:
Synytins, a distinctive feature of which is the presence of points on the overlap and thin hairs. These include only 10-12 species, thus this family is one of the smallest.
Rainbow. Of the main features, the hind legs can be called, which exceed the front length several times, as well as long antennae, reaching ten millimeters in length. Live near aquatic plants. A variety of species in the family varies from 150 to 200.
Rainbow
Cracks. Quite primitive in comparison with other families that live in most climatic belts. Some full information about the number of species or appearance is unknown.
Crack
Cliters, which are also not particularly studied, but have up to two, or even three thousand species in their composition, thus becoming one of the most numerous families.
Clitrina
Emolpines. It is this subfamily that is considered the largest, as well as one of the most ancient. It cannot be ruled out that just all the rest went from the ancestors of this family. The number of species reaches ten thousand.

Lifestyle and behavior
The lifestyle of these insects depends on the feed plant, which they eat as food. Wintering occurs underground, since leaflets have no predisposition to migration. The propagation period falls out at the end of May or the beginning of summer, since by this moment individuals are able to stock up on a large amount of nutrients and feed offspring as soon as possible. In addition, the larvae of leaflets eat specifically the plant on which they grew up, and then pupate. The ripening period of an adult individual in the doll lasts about a week, and the young beetle immediately after the birth begins to destroy garden crops.
Where they live
Listoists are considered the most common species of beetles in principle, which is why the family does not have a certain habitat, since many thousands live on the territory of the entire globe, with the exception of the Antarctic and the zones closest to it. In the CIS alone, scientists have about three thousand species, and in Siberia alone, their number reaches five hundred. All these factors indicate that the beetles of leaflets are common around the world and it is simply impossible to call some exact framework, because all this will be a vague lodge.

What they eat
Only paying attention to the name, without any problems, one can understand what representatives of this family eat. In their diet there are not only agricultural or garden, but also wild cultures, so some species do not bring harm to a person. Each of the feed plants accounts for about two or three types of leaflets. Cucumber, parsley, sorrel, as well as trees and shrubs all this dies from the attacks of adults, as well as larvae. Their feeding does not stop with the arrival of the night, rains or strong winds are also unable to prevent these pests from destroying vegetation. Thus, most agricultural species suffer precisely from representatives of listel insects, and their number allows not to pay attention to the threat from people, because not all means of struggle work.
Interesting Facts
- Listenians are far from always. Thus, several thousand species, on the contrary, can help nature, for example, eating a sick foliage, they save a tree, although, it would seem, they eat at his expense. This is an equivalent exchange, since foliage, which various individuals of other species do not fully eat up, only harms the tree, and leaflets can save it.
- One of the key features of all representatives of the family can be called an unusual appearance when they proceed to the meal: sitting on the foliage, they bend their paws and antennae for themselves, creating a kind of hill that can not even be noticed. That is why many can accidentally kill the leaflet, since he can not always catch on his food tightly and flies away without any problems if you are reduced by the tree branch.
- Some of the species during evolution acquired the same color as their natural enemies, so they are masked in nature and calmly eat. You can often notice how this insect lives near its enemy, who does not even suspect anything. They are mostly similar to God’s cows, but can also be like other animals.
- In addition, since representatives of this species do not always stand out in size and may not even reach a centimeter in length, they are very easy to confuse with a small leaf or kidney, especially if you take into account that they may have the same color as they have the same color At the foliage.
