Why does a ladybug need such a bright outfit?

“Ladybug, fly away to heaven” - these are the words of a well-known children's song that children pronounce when a red bug with black spots located on bright elytra slowly crawls on a small palm.

In Western Europe, the beetle is called the God’s sheep, the sun bug, the sun calf; in our country it was called the ladybug.

With the onset of spring, beetles fly from place to place, sit on their hands, face, clothes, trees, then take off again in search of food. The bright color of the shiny elytra attracts universal attention.

Ladybug (Coccinellidae).

According to our ideas, ladybugs are beetles with red or yellow elytra, with seven or five points arranged symmetrically.

But insect connoisseurs claim that on the backs of cows there may be patterns in the form of commas, dashes and even in the shape of the letter M, and sometimes their backs are decorated with intricate ornaments.

Ladybug is a beautiful insect.

For what purpose did nature award such a bright outfit to a small bug? This color is threatening and warning. No one remembers the pale beetle, and the bright catchy coloring allows you to recognize the insect from afar. The bird will try a bright insect that releases a drop of caustic liquid and no longer tries to eat a tasteless bug. Neither frogs nor lizards eat ladybugs, even spiders, and they refuse caustic insects. Even the Central Asian poisonous spider - the tarantula refuses such food, the ladybug is too tough for him. When she eats to penetrate the spider's mink, he drives her out, pushing the bright insect with the blows of her forepaws.

Children simply adore these colorful insects. they like to play with them in summer and spring.

The whole secret of the peculiarities of ladybugs is the poison cantharidin, it is contained in an orange drop of caustic liquid. When pressing on the body of the beetle, it releases poisonous yellowish liquid through the channels in the paws. This is due to the special structure of the knees of the ladybug. When tightening the legs, a caustic drop immediately appears. This poison, contained in a liquid, unpleasantly burns the pharynx of birds and other animals. The yellow liquid produces an unpleasant odor, and this is not to everyone's taste. Poisonous cantharidin serves as a reliable protection against predators. Some beetles are even masked by its color, hoping that the birds will not touch them.

The ladybug is a real predator, although she looks quite peaceful. Among the cows there are few herbivorous species. The basis of nutrition is aphids. For a day, a ladybug eats a hundred, or even more aphids. Therefore, lovers of gardening and gardening welcome the appearance of ladybugs on their landings, bugs - perfectly protect fields, gardens and kitchen gardens, because aphids are very harmful to plants.

Flight of the ladybug.

On the underside of the leaf, a ladybug leaves a clutch of orange eggs, and after a week thick larvae appear from them. They are usually painted dark with a red or yellow characteristic pattern and are quite mobile. Larvae are voracious, for their full development at least a thousand aphids are required. The fertility of a female depends on the number of aphids; the more food the ladybirds have, the more fertile they are. On average, the female lays 300 orange eggs.

There are many varieties of ladybugs.

Rodolia, a bright red beetle with a black pattern, is one of the species of ladybug known for preserving citrus plants planted on plantations in many countries. The pest, a grooved worm that was not afraid of even hydrocyanic acid, was imported from Australia. The abundance of pesticides could destroy the citrus trees, so people decided many rhodos, which from time immemorial have fed on the grooved worm.

In Japan, ladybirds are specially grown in laboratories, as aphids cause considerable damage to plants planted in the fields. Ladybugs cope well with pests. In the United States, there was a company that specifically grew these bugs to protect plants. In summer, farmers bought ladybugs and with their help they fought against agricultural pests, not wanting to use toxic chemicals hazardous to human health.

Ladybug is a pretty bug with predatory habits.

There is a lot of mystery in the behavior of ladybugs. A special feature in the life of ladybugs is the so-called "gatherings", when beetles from time to time they gather in the hundreds and just sit, doing nothing. Biologist O. Gusev on a sunny July afternoon on the shore noticed a many-kilometer narrow "path" of ladybugs. While observing the bugs, the biologist noted that the bugs flew from the taiga and gathered in a large cluster. Ladybugs fly away, talking peacefully with their relatives.

A small cute bug brings enormous benefits in pest control. Interesting facts are when our ancestors in the distant past placed a living ladybug on a sick tooth and crushed gums with a crushed bug, toothache after a while passed. People even escaped from measles with the help of these bright and cheerful sun insects, with the symbolic name of a ladybug.
