What is the name of the red beetle with black dots?
Many people admire insects, not at all suspecting that some of them inflict huge damage to agricultural crops. There are about 760 thousand species of various insects on the Earth, among them beetles - more than 300 thousand.
The order of beetles is subdivided into three suborders: ancient beetles, carnivores and antagonists. In the first, richly represented in the past, there are only a few dozen existing species today, but it is the starting point for the other two. Among such diversity, against the background of greenery, there are red beetles with black dots and, conversely, black with red spots.
The article provides information on the more common and frequently occurring ones.
General information on beetles
Before we find out what red beetles with black dots are called, we learn what insects are - beetles.
This is the most diverse and numerous by species insects that live in almost all areas of land and water - in the tundra, deserts, mountains, forests, fresh water, and even human habitation.
Each other beetles differ greatly in appearance and in size. Some are so miserable that they can not be seen, others, for example, like a Goliath beetle, can reach 15-centimeter length.
Features of the structure of beetles
A red beetle with black dots on the wings (shown in the photo below), like all other species of beetles, has its own structural features. The main distinguishing feature of beetles is strong and rigid front wings (or elytra), in a folded state forming a chitinous shell, protecting a thinner second pair of wings - membranous.
There are so many creatures in the world who want to eat bugs, that the second one had to acquire such a chitinous hard armor to protect the body. Like all insects, beetles have a head, thorax (abdomen) and chest. Their jaws (only three pairs) are extremely powerful and strong. Most beetles have good eyesight, but mostly they rely on sensitive touch organs - antennae antennae located on the sides of their head.
The heart is located inside the abdomen, and it is protected by a firm thoracic plate (pronotum). Also in the belly are the intestinal tract, stomach and the entire respiratory system.
Many beetles have two pairs of wings, of which the lower ones are used for flying, hidden in a sitting position under chitinous elytra. Before taking off, the beetle lifts the elytra, and only then spreads its delicate, thin wings.
In total, as in other insects, the beetle has 6 legs attached to the thoracic part of the trunk.
Family of ladybugs
These cute little bugs are familiar even to small children. They are well known for their lack of fear of people and their bright red color.
To a greater extent, a ladybird (a red beetle with black dots), seven-pointed, although their species diversity is huge, is known.
In total, there are 5,200 species in the world of the Ladybirds family, in the Hardwing family. Hence, their relatives are numerous varieties of beetles. Some individuals have a red color with black dots, others instead of spots have spots of irregular shape, others - black with spots of red. Very rare, but there are ladybugs monochrome, with black color.
Description of ladybug
These are small red beetles with black dots (the photo can be seen below) with a round bulging body. The lower part of their torso is completely flat. The usual coloring of them is red, black and yellow contrasting tones. The head is small. Legs short, thin, black. The length of the body is 5-8 mm.
In sunny weather, these heat-loving insects are active: they creep hastily, quickly take off and re-sit down on plants in search of food. Their flight is very easy, fast and silent.
Typically, the victims of ladybirds are inactive insects, and therefore hunting for them is only eating the victim.
Distribution, features
Distributed by ladybugs all over the world. They live on all continents of the world, except for Antarctica. Ladybirds inhabit open spaces with herbaceous vegetation - gardens, meadows, forest edges, steppes, less often - forests. Accumulations form only during wintering, and so live alone. In search of food, they creep along the leaves and stems of plants, and can also fly over long distances.
The peculiarity of these beetles is that, in case of danger, they emit a rather sharp-smelling, poisonous, yellow liquid that repels enemies. Only a few species of these beetles are harmful to crops. The remaining (predatory species) destroy chervets, aphids, leaf-blocks and other pests of garden and garden crops.
Not always a ladybug - a red beetle with black dots (photo shows it). Some of the varieties have a yellow outfit with black points, others are painted black with red dots. There are even white ladybugs! All these are young beetles that recently appeared from a pupa. Adult, the usual coloring they acquire after a few hours after the birth.
Varieties
Among the numerous varieties of ladybirds, there are, as noted above, not only red beetles with black dots, but also black and red in color.
- The four -spotted cowbill is a black beetle with 4 red large spots on the elytra and a body length of up to 6 mm. This is a common ubiquitous form. They destroy colonies of inactive insects, sucking off the juices from plants: chervets, shchitovok and Hermes.
- Two-point cows are a changeable in appearance. Usually it is a beetle with a black pronot and with red-winged elytra, each with a black spot. The body has a length of up to 5 mm. Destroy (like beetles, and larvae) aphids.
- The cow is broad-browed - a black beetle with 2 spots of red on the elytra. The body is 3 mm long and covered with hairs. Both larvae and beetles feed on scabs and aphids, and for a full cycle of their development one beetle can destroy more than 600 pests.
Beetle red with black dots
His name is a bug-soldier. This red insect is known to almost everyone, because it lives next to a person.
These beetles, which have a bright black and red color, can grow to a length of up to 12 millimeters. They do not know how to fly, because they do not have wings. Although there are exceptions.
The larvae of this beetle are very similar in appearance to adult insects.
Propagation and behavior of soldiers
Beetles live on the territory of Eurasia in temperate climatic zones, and also occur in North Africa and North America. Bedbugs can be seen almost at any time of the year, except for winter. Especially there are many of them in the spring, when the sun warms well. They sit in small groups in open spaces.
On the trees, red beetles with black dots favor the old bark. They are located on loose boards, on bricks, on fences, and even in houses they can be seen in rural settlements. In fact, these insects are completely harmless.
The composition of their diet - fruits that fell to the ground, seeds, plant juice. Their main feature is that they sometimes eat their relatives when they live in large colonies.
At the end of autumn, beetles with a red back and black dots lie on wintering under fallen leaves, under bark of trees and in other places, sheltered from wind and strong frosts. With the onset of winter, soldiers enter the stage of an adult insect. Nature endowed them with an unpleasant odor to scare off natural enemies.
Shrenk's Shredder
To red beetles with black dots, it is possible to include a beetle - a scimitar of Shrenk. He is easily recognizable by his bright characteristic appearance. The wingguards are red or orange, with transverse stripes and black spots. The body is distinguished by a dense hairiness.
On sunny days these beetles can be seen sitting one by one or several individuals on flowers. Usually they are slow and sluggish. The larvae are more mobile than adults. Penetrating into the locusts, they feed on their eggs.
These insects got this name because they contain poison (cantharidin), which irritates the skin and causes the appearance of water bubbles (abscesses). It can also happen that an animal that swallows this beetle with the grass will fall ill and die.
Conclusion
Among the huge variety in the nature of beetles, ladybugs are the closest to humans and pleasant outwardly and sweetly.
They are associated with childhood, when these beetles themselves sat without fear on the palms of their hands, and the kids asked them to fly to "nebko" to feed the children. These beautiful insects are always a favorite object of children, because they are well accessible for observation.
English coloring of the ladybug is interpreted as follows: red color is a reminder of the passions of Christ, and black dots are associated with the 7 sorrows of the Mother of God.
