Mantis

Arthropod insects from the order Praying Mantises received their Russian name due to the fact that their forelimbs are similar to human arms, bent in the hands.

While in ambush, they take a wait-and-see attitude. In the photo of praying mantises you can see this behavioral feature. This posture is associated with the position of the body of a person reading a prayer.

What it looks like: structure and characteristics of a praying mantis

Structure of a praying mantis
As a rule, praying mantises have an elongated body, which is a distinctive feature of these insects. Praying mantises are one of the few insects that can make a full rotation of their head around its axis . This is why they can easily spot enemies from behind. The insect has only one ear, but its hearing is excellent.

Mantis eyes

Mantises have compound eyes that are located on both sides of the head.
There are also three elemental eyes above where the antennae grow. The mantis' mustache, in turn, has a comb structure and can also be feathery and filamentous. The type of whiskers varies depending on the type of insect. Interesting fact : praying mantis is one of the varieties of wushu.
According to Chinese beliefs, this style was invented by a peasant who had been watching mantises hunt for a long time. Most varieties of mantises are equipped with wings, but only males can use them for their intended purpose. Females are unable to fly due to their large size and weight. Each insect has two pairs of wings - front and rear. They are usually brightly colored, sometimes with beautiful patterned designs. However, there is one species of mantis that has no wings at all - the ground mantis.

Mantis - structure and characteristics

Each mantis is well built and has developed front legs with which it can grab prey. The structure of the forelimbs is as follows: acetabular rings, femurs, tibiae with hooks at the ends, and paws. There are sharp spines on the lower part of the thighs, and there are also smaller spines on the lower leg.

Mantises clamp the caught food between their legs and thighs. They hold it until they eat it completely. Due to their unusual respiratory apparatus, praying mantises have the simplest circulatory system. Oxygen enters the insect's body through a complex chain of several tracheas, which are interconnected by stigmata.

Nutrition

It is no secret that our hero is a notorious predator who loves to feed on both smaller insects and is not afraid to attack larger prey even than himself. Flies eat them,

mosquitoes, bees, wasps, bumblebees, butterflies, beetles, etc. Large representatives of the praying mantis family (see above) can even attack small rodents, birds and small amphibians: frogs, lizards.

Mantises usually attack from an ambush, unexpectedly grab the prey with their front paws and do not let go until they have completely eaten it. Strong jaws allow these gluttons to eat even relatively large prey.

Dimensions

Ischnomantis gigas
The most important difference between the sexes is size. Females are much larger than males. The largest species of mantis, Ischnomantis gigas, lives in Africa; it can grow up to 17 cm in length, holding the record for its size among all mantises.

The second longest species of mantis is Heterochaeta orientalis. The record sizes of these representatives of mantises are slightly smaller - up to 16 cm. The simplest representatives of the species grow no more than 1.5 cm in length.

Interesting fact : in the USSR there was a plan according to which mantises could be used as protectors against agricultural pests. However, the idea was not realized, as predators killed the bees.

Rhombodera basalis

A large praying mantis from the genus Rhombodera can be found among the tropical forests of India, Thailand and Malaysia. Prefers to settle in humid and warm places. Adults grow up to 9 cm.

It differs from other species in its chest shield. The color is turquoise-green with a blue tint. Because of its beauty and calm disposition, it often becomes a resident of home aquariums.

Habitat - where does the praying mantis live?

Habitat of the praying
mantis Mantises are distributed throughout the planet. They are in Europe, Asia, Africa and America. A wide variety of mantises have been recorded in Asian countries. A few species can be found in the CIS countries. Insects were also brought to Australia and North America, where they were able to take root.

Praying mantises live in tropical and subtropical areas:

In tropical rain forests.
In hot deserts, where the merciless sun constantly bakes.
In meadows and steppes, completely covered with thick grass.

The praying mantis is heat-loving.
By nature, praying mantises are heat-loving. They have a hard time withstanding low temperatures. Now in Russia you can find real invasions of mantises migrating from other countries. They are looking for food and new habitats.

Such migrations occur very rarely. Praying mantises prefer to live in already inhabited territories. They will stay in the same tree throughout their lives, as long as there is food there. Movements of insects are observed mainly during the mating season, when territories are depleted and when there is danger.

Habitats

Almost everywhere, since their habitat is very wide: Central and Southern Europe, Asia, North and South America, Africa, Australia. They are only absent in the northern regions, since mantises are not very accustomed to the cold. But they are perfectly suited, for example, to the hot and humid climate of tropical Africa and South America. Praying mantises thrive in tropical forests, steppe regions, and rocky deserts.

They rarely move from place to place, preferring their usual habitat to unknown distant places, the only reason that can prompt them to travel is the lack of food supply.

Why does a female praying mantis eat her husband?

During mating games, a female can eat her partner, confusing him with a potential victim. Also, females eat males for the reason that a lot of protein is required to bear offspring. In this case, not only partners are attacked, but also other representatives of the species.

Before mating, the male dances in front of his partner, releasing an odorous substance. The smell indicates that the insect belongs to the same genus. Sometimes the female may not eat the male, but this happens very rarely. First, the gentleman loses his head, and then the female completely eats him.

Predators also hunt very gracefully. They are quite maneuverable and can catch and kill a prey in a matter of seconds. A distinctive feature of insects is that they perfectly control all their movements in flight.

Color and camouflage

Praying mantises have excellent camouflage abilities. Their color and shape depend on the place of existence. Some mantises may be green, others brown, or even variegated. The color of an insect depends on its environment. Green mantises can be missed in the grass, brown ones on the ground. Variegated praying mantises look like this to attract females.

Color and camouflage of praying mantises

Some insects can have different shapes, masquerading as leaves. This way they become invisible to enemies. If someone attacks an insect, it begins to open its wings and try to look bigger.

Blepharopsis mendica

The calm, non-aggressive insect is also called the “devil’s flower” due to its color and body structure. It was discovered by the scientific world in 1775 by the Danish zoologist Johann Sebastian Fabricius.

At the moment of danger, they spread their wings wide and raise their limbs to scare away the enemy. They live in semi-desert and mountainous regions of Southeast Asia and northern Africa.

Reproduction

Little praying mantises
Mating games end tragically for the males. The female rips off their head and completely eats the male. With the onset of mating games, males begin to leave their usual habitats in search of a female. At the same time, they look for a mate by the smell emitted by it. When the male finds a passion, he dances with the release of a special secret. Only after the dance will he be considered as a partner. The female does not kill her partner on a mere whim. This way she provides her offspring with a supply of nutrients.

Interesting fact : since ancient times, praying mantises have been attributed mystical significance; they have become heroes of various legends. So, in Asian countries, stubbornness and ruthlessness were attributed to praying mantises, and among the Greeks they were considered harbingers of spring.

Praying mantis egg laying

Sometimes the male can escape from an unsightly fate, but in this case the female can kill herself. When the female lays eggs, she completely covers them with a sticky substance secreted by special glands, this protects future offspring. Female mantises can lay up to 400 eggs, depending on their species. The eggs take up to six months to develop. The larvae can develop very quickly and after the fourth molt they become similar to praying mantises.

Why is the praying mantis called that?

The name praying mantis, established academically, first appeared in 1758. The insects were so named by the Swedish naturalist Carl Linnaeus. He observed the insects and made an interesting remark that they looked like people diligently praying to God. Indeed, the forelimbs of praying mantises seem to be folded in constant prayer. The insect was nicknamed "Mantis religiosa", which means "religious priest" in Latin. In the Russian interpretation, the name “mantis” has taken root.

Carl Linnaeus was the first to scientifically describe the praying mantis

At the same time, the insect is not called a praying mantis in all corners of the planet. Mystical meanings are often attributed to praying mantises. In Spain, for example, the praying mantis is associated with death and is nicknamed the devil's horse. Such names can be associated with the cruel habits of mantises, which terrify people.

Praying Mantis – an Alien Insect.

Population and species status

Numerous populations of mantises are gradually decreasing. However, this feature is characteristic only of insects in the European part of the world. In African and Asian countries, praying mantises continue to breed. Great harm to populations is caused not by their natural enemies, but by human activity. People are destroying the natural habitats of mantises, cutting down forests and destroying fields. Sometimes there are situations when one type of mantis displaces another from certain territories. Sometimes genocide occurs, since praying mantises are very voracious.

Since insects are predominantly heat-loving, they do not reproduce well in cool areas. The larvae also develop more slowly, so complete restoration of the population takes a lot of time. Old generations have time to die out before new ones appear. To preserve the population, people try to minimize the damage caused by human activity to the environment.

Choeradodis rhombicollis

This unusual insect lives in mountainous Peru. The shield mantis is very difficult to see among green foliage, as it is easily disguised as green leaves and shoots of plants.

In total, the genus Choeradodis includes 5 species, differing in size and body structure. Some species from Peru moved to Central America, easily adapting to new living conditions.

Benefits and harms for humans

Despite their aggressive behavior, praying mantises do not pose a danger to humans . Even despite the large size of some members of the family.

Mantis Spikes

The only harm a praying mantis can do to an adult is to injure it with its claws. For this reason, you should not allow small children near praying mantises . The character of insects is far from ideal.

Predators are useful for agriculture as they eat many agricultural pests. In Africa, praying mantises are brought into houses where they eat flies. However, praying mantises are insatiable - they can destroy beneficial insects like bees.

Keeping praying mantises at home

Terrarium for a praying mantis
Praying mantises are suitable for keeping in terrariums. They are taken into homes where they are given proper care. The most comfortable conditions for keeping praying mantises are:

Temperature range – 20-30 degrees Celsius.
Humidity levels of the terrarium are at least 60%.

There is no need to feed insects; they get everything they need from food. In the wild, small species of mantises are replaced by stronger and larger ones, and sometimes complete extermination of a species in a certain area can occur.

For praying mantises, special conditions need to be prepared. The decision to get such an exotic pet can be considered a very interesting act on the part of a person. The terrarium does not need to be large. Praying mantises only need a small area in the form of a plastic or glass container. The lid of the terrarium should be made of mesh, and its dimensions should accommodate at least three more such mantises. It is better to add twigs or plant plants in a terrarium. This way the insect will be able to climb on them as in natural conditions.

As mentioned earlier, praying mantises prefer a humid environment with a temperature of 20 to 30 degrees Celsius. They feed on other insects. On sale in pet stores you can find various bugs and ants that will become live food for the praying mantis. Feeding should be regular, but praying mantises do not need a drinking bowl.
