To the question: How many dots does a ladybug have on its back? given by the author Neuropathologist the best answer is In very ancient times, peasants noticed that if there are a lot of such bugs in a garden or field, there are always good harvest. And since among the people everything good was associated with God, they called these bugs “God’s”. When you take a bug in your hand, it secretes a yellow droplet, like milk. So the word “cow” was added.
ladybug seven-spotted - the earliest, most classic.
Ladybug Galizia will teach you how to count: How many dots are there on the back of a ladybug? up to twenty-seven - that’s exactly how many dots are on her lemon elytra. This is a record among our cows.
The ocellated ladybird is interesting. On its brownish-orange elytra we see fourteen black dots surrounded by light rims - they look like real eyes. The effect is excellent: the many-leaved dome is crowned with a spikelet of timothy!
Sometimes the dots on the elytra connect, and then we see something similar to a hieroglyph. This is exactly the mysterious sign that the patterned cow bears.
The variability of the two-spot ladybird is amazing. How many times have I sat over the definition of its varieties! Well, what do these forms have in common: elytra with two small dots - and elytra with a complex black mesh superimposed on a red background.
By the way, an interesting fact: if you touch a newly born “cow” and force it to move, then there will be exactly as many spots on its back as appeared before the moment it was “disturbed.”

Well, it depends on the type of insect.
There are seven-point ones - they are the most common, there are 5-point ones. These are the ones that are “red” and the dots are black
There are also small ones, reddish and black. They have more dots - up to 22

my child was told in the garden that the amount depends on age
Reply from Irina[guru]
The children always explained to me that no matter how old she is, there are so many dots. Unscientific, of course, but we learned to count :)
Reply from User deleted[guru]
As old as she is.
Reply from Tatyana Pushkova[guru]
in my opinion - 6.
3 - on one wing, 3 - on the other.
P.S. I've never seen a ladybug, for example.
with 1 point or 2... (speaking of age)
Reply from Ivan M. Pchelin[guru]
There are as many dots as you want: lots of different types.
BROTHERS!! The number of points does not depend on the age of the creature!
It just depends on the type. As a beetle, he was born in his beetle guise, and will remain so for the rest of his life. The pattern will not change, the leg will not grow.

There are more than 1000 species of ladybugs (lat. Coccinellidae) in the world. They live in different places: some took a liking to the plants on which aphids are found (these are apparently the laziest, or better yet, pragmatic - food is always close at hand), others have their eye on the indescribable beauty field herbs, others liked the meadows overlooking the stream, some preferred to sit on the aquatic plants.
The most common species appears to be the seven-spotted ladybug (Cocinella septempunctata). Its black breast is decorated with a whitish spot in the anterior corner, and there are seven black dots on the red elytra (three on each elytra and one common scute). It is found in Europe North Africa, Asia and feeds on aphids.
According to the ladybug atlas, you may encounter a ladybug with the number of spots from two to twenty-six.
Seven-point has been known to everyone since childhood. Many children are not afraid of this insect. They come up with a lot of fairy tales and funny rhymes about him. This type first described in 1758. This red insect, according to entomologists, brings great benefit to people. It destroys harmful insects causing damage to plants in gardens and vegetable gardens.
Where does this insect live?
Of all the species, the most famous is the seven-spotted ladybug. It can be found in all European countries, except for the northern zones. In addition, this bug is found in North Africa and even in Japan.
But in North America, the insect could not bring much benefit. Despite the fact that it was brought to the continent, the red ladybug could not take root. There are only a few species left in North America that do not produce the desired results.
This insect prefers to live in grass groves, as well as in forest plantations, meadows, fields, plains and ravines. It is during the autumn period that ladybugs form large columnar flocks. The number of accumulated insects reaches several thousand.
Description of this species, developmental features
Initially, the ladybug has the appearance of a larva, the size of which does not exceed 1 mm. It only takes her one month to move to a new level of development.
Then it already has a size of 8 to 10 mm. The body of the larvae is usually gray in color, but the head is yellow. The spots on the sides of this insect are also of the same color. The body has segments on which black spines with hairs can be seen.
In order to get food, such a larva can climb to a height of up to 12 m. During the day, to be full, it needs to absorb about 100 adult aphids or 300 of its larvae. After a month, the larva enters the pupal stage. It takes about 12 days for a ladybug to fully develop and mature. But it all depends on the air temperature: the warmer it is, the faster the pupa will turn into an adult ladybug.
Description of the adult
The body, wings and abdomen of an adult insect are black. The wings are mainly red or orange in color with spots characteristic of this insect (7 points). For this reason, the seven-spotted ladybug was named so. Three points are on one red wing, and the same number on the second. But the 7th spot can be seen near the beetle’s head.
Adult ladybugs begin to appear outside in the first half of June, when it begins to warm up. In places where the heat comes faster, you can find ladybugs in May.
They eat aphids and can eat up to 60 adult pests in a day. A ladybug lives from several months to two years. The description of the larvae indicates that for growth and rapid development they eat many more aphids than adults.
Reproduction
A female ladybug can lay about 1,000 eggs throughout her life stage.
The eggs of these insects are oval. They measure up to 1.2 mm. The color of the laid eggs is orange. The shape of the masonry generally looks like a small pile. At one time, an adult female can lay from 20 to 90 small eggs. Basically, such masonry is located in safe places, that is, under leaves, blades of grass, at the base of branches.
A large number of ladybugs can be observed precisely at the end of summer, when two generations of beetles have already hatched and developed. The larvae do not overwinter, since only adults can survive this period.
What types of ladybugs are there?
More than 4 thousand types are known. Ladybug species are divided into 7 subfamilies. Of these, the most interesting and popular types are distinguished:
Ladybug 2-point;
7-point;
12-spot ladybug;
13-point;
14-spot ladybug;
17-spot ladybug;
Asian ladybug.
What does this insect eat and what benefits does it bring to humans?
The seven-spotted ladybug is a predator. Moreover, at any stage of its development, it feeds exclusively on other bugs. Mainly eats various types of aphids that live on all kinds of plants and trees. In addition, the bug eats the eggs of other insects: etc.
This beetle can most often be observed on fruit trees, currant bushes, as well as on pine, aspen and bird cherry. The presence of such plants in the regions of our country indicates large number insect data.
What do gardeners think about the seven-spotted ladybug? How to attract this insect?
Is the seven-spotted ladybug a pest or not? Many gardeners, of course, will answer no. Thanks to this small insect it is possible to save a significant amount of the crop. Aphids, which eat and damage many plants, are the ladybug's most important food source.
Those people who prefer not to use for their plants chemical compositions to destroy pests, they believe that the best assistant will be the ladybug. But in order for the benefits of this insect to be more tangible, you need to maintain appropriate conditions in your area for comfortable life these red insects. To do this, you should not destroy all aphids in the spring, and especially resort to harmful chemicals, because then the ladybug will not fly. It is better to leave a few aphids so that our insect can eat. This will attract ladybugs and they will stay in your area for a long time. long time, helping to fight numerous pests.
Conclusion
Now you know what a seven-spotted ladybug is, what it looks like, develops, and what it eats. It turns out that such a small bug can be of great benefit! In order to attract him to your garden or vegetable garden, you don’t need to do anything special - you just need to let him natural processes proceed naturally. Remember that in nature everything is interconnected, so it is important to maintain this overall cycle. It is also worth thinking about completely abandoning the use of all kinds of chemicals to protect the crop. Nature can take care of itself, you just need to help it a little!
Ladybugs are gardener's assistants.
These bugs, familiar to everyone since childhood, as well as their larvae, are natural enemies of aphids. Cute and beloved ladybugs are everyone's favorite helpers for gardeners.
Europe is home to only 100 species of ladybirds, or coccinellids, of the 5,000 members of this large family. Most species of ladybirds live in tropical and subtropical climates. Even the seven-spotted ladybug, familiar to us all, needs warmth. On warm days, ladybugs lead an active lifestyle - they fly faster and more. On cool days, ladybugs are less active.
The number, color and shape of the dots on the elytra of these insects have become distinctive features various types. The number of dots, contrary to popular belief, does not say anything about the age of insects. Most of the ladybugs living in our latitudes feed on aphids. Others feed on coccids (scale insects and mealybugs), spider mites and even whiteflies. Very few species of ladybirds feed on plants and fungal spores. Many types other than animal food. They also eat plants - they feast on pollen and nectar. Not all ladybugs specialize in eating different types of aphids; some feed only on certain species, so they travel a considerable distance in search of food. The availability of food and weather significantly influence the development, growth rate and increase in the number of ladybugs.
Females reproduce only when food is available, then their eggs mature. Each female lays 400 yellow eggs in groups of 10-30 on the underside of a leaf, usually near an aphid colony. Ladybugs feed on coccids and lay eggs under the shell of pests. The larvae hatch from the eggs after 7-10 days. The larvae are long, dark-colored. They go through four to five growth stages before pupating. During this period, the larvae must actively feed. After 3-6 weeks they pupate on leaves or tree trunks. The pupae are round. Painted orange or black. After four to nine weeks, the pupae hatch into yellow-orange beetles with pale spots on the elytra. Full cycle The development of a ladybug lasts from one to three months. Ladybugs give birth to one to two generations per year.
It is better to refrain from using chemical pest control products. Adult ladybugs and their larvae are very sensitive to insecticides. In the spring, we do not spray plants with chemicals against aphids, as we will deprive the adult generation of cows of the food necessary for laying eggs. You can help ladybugs by growing trees and shrubs in the garden on which various types of aphids will settle. In addition, ladybugs will find on them good place for wintering.
As for wintering places, the following may be suitable for this purpose:
Hedgerows and piles of brushwood will present safe place for wintering. We leave piles of fallen leaves and brushwood in the garden until spring. Dry rocky walls and old trees with deep crevices in the bark are perfect place for wintering ladybugs. An entire colony of ladybugs can overwinter in sheds, woodpiles and birdhouses, as well as in the walls of wooden houses. Ladybugs can overwinter in a piece of wood in which suitable holes have been drilled, or in bundles of reed stems. You can also help ladybugs, since they are among the worst natural enemies of aphids and some other pests. They don't have special devices to hunt aphids, therefore, having eaten pests, they move to another plant in search of food. Ladybugs fly around many plants during the day. Searching for food takes a lot of their energy. Adult beetles (seven-spotted ladybugs) eat up to 150 aphids per day, and more small species– about 60. The larva of the seven-spotted ladybug eats at least 800 aphids for further development before pupation.
If suddenly you come across a ladybug in your garden that is more different than what you are used to seeing, then here is brief description types of cows:
Ocellated ladybird - length 8-10mm, yellow-red elytra with 20 black dots with light edges, found in forests, usually in pine forests (feeds on lice beetles), as well as on garden trees and bushes.
The despotted ladybird is 3.5-5 mm long, the elytra are dark red or dark brown, each with five black dots, the most numerous of the species that prey on aphids in meadows and among tree or shrub plantations.
Fourteen-spotted ladybird - length 3.5-4.5 mm, over 100 different shapes, elytra red or yellow with 14 dark spots, preys on different types of aphids.
Spot ladybird - length 1.3-1.5 mm, black hairy elytra, yellow legs and antennae, lives on deciduous and fruit trees, feeds on spider mites.
Ladybug 22-spotted - length 3-4.5 mm, long lemon-yellow beetle with 22 black spots, does not eat aphids, feeds on mealy fungi on trees, bushes, meadow plants and grapes e.
The ladybird is streak-spotted - length 7-9mm, black elytra, decorated with numerous yellow spots. It feeds on aphids that attack coniferous trees.
Like this big family ladybugs, take care of them and feed them with aphids. Good luck to you.
Later it turned out that there are more than 1000 species of ladybugs (lat. Coccinellidae) in the world. They live in different places: some liked the plants on which aphids are found (these are apparently the laziest, or better said, pragmatic - food is always at hand), others looked for the indescribable beauty of field grasses, while others liked meadows with a view on the stream, some preferred to sit on aquatic plants.
The most common species appears to be the seven-spotted ladybug (Cocinella septempunctata). Its black breast is decorated with a whitish spot in the anterior corner, and there are seven black dots on the red elytra (three on each elytra and one common scute). It is found in Europe, North Africa, Asia and feeds on aphids.
This is what a two-spotted ladybug (Adalia bipunctata) looks like.
It is curious that this particular ladybug was approved as the national insect of Latvia in 1991 by the Entomological Society of Latvia. She is useful, slow in nature, but this does not prevent her from defending herself well - it is thanks to her appearance and behavior that she is so loved in Latvia. In Latvian it is called marite, which is the name of the Latvian ancient deity Mara, who embodies earthly power.
And so - with 22 points (Psyllobora vigintiduopunctata).
Recently I read about an amazing cow (Ailocaria hexaspilota Hope), the pattern on the elytra of which is truly worthy of surprise and philosophical treatises. This type of ladybug can only be found here in the south. Far East. She first lives on bird cherry, and by the end of May she moves to Manchurian nut. He loves to eat leaf beetles. It is also surprising that flocks of amazing cows accumulate during the wintering period. Imagine how beautiful it turns out!
No matter how many dots decorate the back of a ladybug, it is beautiful to the envy of all insects and to the joy of people. Let's pay attention to these wonderful creatures!
Once, an artist I knew, who took my “painting talents” under his wing, insisted that six dots must be drawn on the back of a ladybug. Even at that moment I guessed that this was not entirely true. As children, we even believed that the number of dots on the wings indicated the age of the cow.
Later it turned out that there are more than 1000 species of ladybugs (lat. Coccinellidae) in the world.
They live in different places: some liked the plants on which aphids are found (these are apparently the laziest, or better said, pragmatic - food is always at hand), others looked for the indescribable beauty of field grasses, while others liked meadows with a view on the stream, some preferred to sit on aquatic plants.

Ladybug is arthropod insect, which belongs to the order Coleoptera, the family of ladybugs (lat. Coccinellidae).
Where did the name ladybug come from?
The ladybug received its scientific name due to its unusually bright color - the Latin word “coccineus” corresponds to the concept of “scarlet”. And the common nicknames given to the ladybug in many countries around the world speak of people’s respect and sympathy for this insect. For example, in Germany and Switzerland it is known as the “Virgin Mary’s bug” (Marienkaefer), in Slovenia and the Czech Republic the ladybug is called “Sun” (Slunecko), and many Latin Americans know it as the “St. Anthony’s bug” (Vaquita de San Antonio).
The origin of the Russian name for ladybug is not exactly known. Some researchers are inclined to believe that this is due to the ability of the insect, in case of danger, to secrete “milk” - a special poisonous liquid (hemolymph) that repels predators. And “God’s” means meek, harmless. Others believe that these insects received the nickname “ladybugs” because they destroy aphids and help preserve crops.
Ladybug: description, characteristics, photo. What does an insect look like?
The size of the ladybug ranges from 4 to 10 mm. The body shape of insects is almost round or elongated oval, flat below and highly convex above. Its surface in some species of ladybugs is covered with fine hairs.
The body structure of ladybugs includes a head, a pronotum, a thorax consisting of three sections, three pairs of legs, an abdomen, and wings with elytra. The insect's head is small, motionlessly connected to the prothorax and, depending on the species, may be slightly elongated. Ladybug's eyes are relative large size. The antennae, consisting of 8-11 segments, are highly flexible.
The pronotum of the insect is convex, transverse in structure, with a notch on the anterior edge. Often there are spots of various shapes on its surface. In contrast to the prothorax and mesothorax, which are extended across the body of the insect, the shape of the metathorax resembles an almost perfect square.
In total, ladybugs have 6 legs, which are of moderate length. In the structure of each insect leg there are three obvious and one hidden segment. With their help, the insect can move quite quickly along the grass or plant stems. The abdomen of ladybugs consists of five to six segments, covered from below by sternites (segmental semirings).
Ladybugs fly using their two hind wings.
In the process of evolution, the front wings of the ladybug were transformed into hard elytra, which serve as protection for the main pair for the period while the ladybugs are on the ground.
As a defense against predators such as birds, ladybugs secrete cantharidin, a toxic yellow liquid that has an unpleasant odor.
In addition, the bright colors of the cow also scare potential enemies away from it.
The color of the ladybug's protective covering can be bright red, rich yellow, black, dark blue or brown with spots of black, yellow, red or white various configurations.
In some types of ladybirds, these spots can merge into abstract patterns, while in others they are completely absent. Often the pattern on the pronotum is a sign by which the sex of a ladybug can be distinguished.
Types of ladybugs, names and photos
The large family of ladybirds includes more than 4,000 species, divided into 7 subfamilies, which include approximately 360 genera.
Most interesting varieties ladybugs:

- There is also blue ladybug is Halmus chalybeus .
Its elytra have a blue sheen, and its length reaches 3-4 mm. This insect lives in Australia.
Ladybug (lat. Coccinellidae) belongs to the family of beetles, a type of arthropod, a class of insects. When a person sees an insect, he involuntarily has a reaction - to slam it as quickly as possible, but the ladybug evokes sympathy in almost everyone, even women. Some remember the children's song associated with her, others remember that she really helps them out. summer cottage– saves the garden from pests. What is the secret of everyone’s sympathy for this beetle? In some cultures it is forbidden to kill a ladybug, and in the Western part it is generally considered a symbol of good luck. Let's consider the characteristics and lifestyle of this insect, as well as the benefits and harms it can bring.
Today, no more than 200 insect formations have been studied on the planet, but the number of species is limitless. The ladybug is a representative of the coccinellid family, has over 4000 types and 360 genera, belongs to the order Coleoptera of the arthropod type. Distinctive feature from other relatives they have seemingly three-part paws. This is due to the small third segment, which is visually hidden with half of the fourth pedicle in the sinus of the bilobed process.
The average size of a ladybug is from 4 mm to 10 mm. The structure of the body is rounded, ovoid, flattened below and convex above. Sometimes the surface is covered with thin fibers. Consists of a head, pronotum, and chest, which is divided into three parts:
- paws;
- abdomen;
- wings with wing covers.
The head is monolithically connected to the prothorax, everything looks like an enlarged cephalothorax. It makes up the main part of the body length, sometimes found in an elongated oval shape. The eyes are relatively large. The antennae are well flexible and consist of 8-11 segments.
Has rigid expressive elytra. Essentially these are the front flight organs. Over time, the ladybug's wings transformed. On the ground they perform a protective function. With the help of two rear processes, it flies, and it turns out quite well. An interesting fact is that various birds and many vertebrates are hesitant to hunt it. They don’t have time to catch it, because the insect makes about 85 strokes per second.
Why is the ladybug called that?
Where it got its name from remains an open question to this day. The scientific terminology is coccinellida, the word itself comes from the Latin meaning "scarlet". Many ethnic groups have their own versions of names, for example:
- among the Germanic peoples - the “Virgin Mary” bug;
- among the Anglo-Saxons - “Lady bird”;
- among the Slavic - “Sun”;
- among Latin Americans - “St. Anthony’s cow”;
- among Asians it is “red-bearded grandfather”.
There are long-standing legends about why the ladybug is called that, let's look at some of them.
She was personified with the heavenly herd of Perun, connected the omnipotent gods and mortal people, and was credited with magical abilities to influence the weather. The Catholic faith considered her a messenger of the Mother of God. The British also associate their names with the Virgin Mary.
The ancient Slavs considered her the messenger of the sun. It was impossible to drive away the heavenly creature, so as not to turn away fortune. A beetle that flew into a home was considered to bring peace and grace, so they called it that way - “Sun”. The very word “God’s” symbolized among the Russian ethnic group a trusting believer. The beetle was compared to a harmless creature.
But more likely the word “lady” is associated with a physiological feature of the insect. It secretes milk, but it is far from usual - a red aggressive liquid formed in the spores of the limbs. The discharge is extremely unpleasant, large quantities deadly for those who decide to feast on it.
Types of ladybugs
The ladybug is not necessarily red, but its coloring is in the form of dots. They may be absent altogether; there may be stripes, patterned spots, or commas on the shell. The most common type is the seven-spotted beetle. It lives almost throughout Europe, its dimensions reach 7 mm, its elytra are burgundy, and there are two spots at the base. light color, one dark one is visible on the pronotum, there are three speckles on the elytra.
They are also divided according to the number of dots and color:
- two-spotted, usually 5mm dark scarlet individuals with 2 large black markings;
- duodenal up to 6 mm, have pinkish elytra, on which 6 pieces are observed;
- thirteen-spotted up to 7 mm, with brownish wings;
- fourteen-point – with yellow color and black spots on them or vice versa;
- seventeen-point identical colors measuring from 2.5 to 3.5 mm;
- variable, with a black pronotum with 2 brownish spots, contrasting markings at the base of the yellowish-red elytra;
- blue ones are found on the Australian mainland and have a beautiful tint of blue and green tones;
- white or light gray - up to 15 marks, less common, like brown plain ones.
Bright warning coloration of a ladybug
The ladybug is endowed with a bright color, which helps in the struggle for existence and strikes fear into enemies, most often birds. This is one example of mimicry, like the green color of grasshoppers or the ability of a chameleon to merge with environment for the purpose of self-preservation.
The striking colors of the natural wild world serve as warning signals about the toxicity and inedibility of the observed prey. There is a theory that what brighter color beetle, the less likely it is to be attacked by enemies. The expressive color of various types of ladybug indicates mortal danger. As individuals age, it fades.
Ladybugs live almost all over the world except northern latitudes. Their life cycle depends on the availability of food. The active stage occurs during the extermination of aphids, the main diet of these insects, i.e. from spring to autumn. They live from a couple of months to one year, and occasionally last up to two.
A solitary lifestyle is acceptable to them; they settle in groups for wintering or for mating. Feel comfortable on open areas with herbaceous vegetation on:
- the edges of the forest;
- steppes, meadows;
- gardens
In search of food, they crawl through plants, periodically flying over long distances. They do this easily and silently. But as long as an individual lives, it always wakes up early and works all day, destroying pests. She is thermophilic optimal temperature for her it is +10 C, during other periods it is in the winter.
How and where do ladybugs overwinter?
When cold weather sets in, sedentary varieties of ladybirds gather in large groups, sometimes up to millions of individuals. In winter, they look for secluded places, hiding under the remains of falling leaves, dry wood, stones, where they wait for the arrival of warmth. They can fly into rooms and take refuge between window frames, fold curtains, arrange nesting sites among trees.
There are species of beetles that fly away in flocks to winter in southern latitudes. IN lately The features of adaptation to the environment were not only bright colors or toxic liquid released in case of danger. Their group aggregations are becoming more and more observed. This is still inexplicable, but the spectacle is colorful.
If “sleepy colonies” are discovered, do not disturb them. It’s better to think about how many pests will be destroyed in the future. Move them to a comfortable place, having previously collected them in a jar, let them calmly finish their hibernation.
What do ladybugs eat? Are they predators?
Characteristic feature insects of the order Coleoptera have a gnawing type of mouthparts. The ladybug has similar anatomical characteristics. Structure digestive system originates from the mouth opening of the head and ends on the abdomen with the anal passage. The intestinal canal runs between them. This allows the insect to consume complex molecular food with a high energy reserve when feeding.
Simply put, the coccinellid is a predator; it eats its own kind. Diet preferences are given to:
- spider mites;
- small caterpillars;
- butterfly eggs, Colorado potato beetles;
- larvae of insect pests.
There is also a species that feeds on plant foods: pollen, flowers and leaves, mycelium, and fruits.
Ladybugs reproduce several times a year, in spring or autumn. On the territory temperate latitudes- It's the beginning of May. The female becomes sexually mature at the age of 3-6 months. As a rule, after a cold period, she is able to emit a pungent odor that attracts males. After laying eggs it dies.
The female places eggs on vegetation with an abundance of aphids, which provides advance food for future offspring. They have an elongated shape, narrowed towards the end, and are colored yellowish-orange. One clutch can number from several to 400 pieces, arranged in even rows, close to each other. Sometimes they can be eaten by their own relatives, the so-called cannibal larvae.
Ladybug larvae - what do they look like?
Further development occurs over 4-7 days and has several stages. The larvae are oval in appearance. They look colorful due to yellow-orange spots that form a certain pattern. Body surface with bristles, peculiar outgrowths. Newborn ladybugs that feed on scale insects are covered with whitish, waxy threads. Everything grows in 2-4 weeks.
After this stage the moment of pupation occurs. To move into it, the individual attaches the back of the body to the leaf plate and curls into a semi-bent position. At the end of the internal transformation, the skins peel off from the pupa, sliding like a stocking to the end of the abdomen. It does not lose its bright color with black and yellow specks. Next, from 7 to 10 days, an adult is formed.
The benefits and harms of ladybug
The boundless gluttony of this predatory beetle brings great benefits to homesteads and agricultural crops, because it eats aphids. While in the larval stage, the coccinellid consumes up to 50 prey per day. Adult insect eats up to 100 aphids. They help plants by clearing crops of pests. Therefore, they are even bred at specialized enterprises, and then distributed over the fields with the help of aviation.
But harm can be caused by herbivorous species of these beetles; their habitats are in Asia. There they cause significant damage to crops. In our area, some harm vegetables: potatoes, sugar beets, tomatoes and cucumbers.
Enemies of ladybugs
How many species of ladybugs, numbering thousands, would not exist; the insect has long been placed on the pages of the Red Book of not only Russia, but also the planet. They don't have many enemies. Birds, frogs, lizards try to eat them, but innate effective means protections prevent them from becoming food for many.
Indirect factors of extinction are human impact to the natural environment. There is a massive destruction of aphids, on whose populations the existence of the beetle depends. General environmental pollution is also destructive for all animals.
The ladybug is an ancient insect. This is not the only reason why the law protects it from extermination. Mass extinctions will lead to a deterioration in the condition of not only cultivated vegetation, but also the entire nature. To maintain balance, humanity needs to be more attentive to this problem.
