Someone used to see bedbugs peacefully swarming under the roots of trees (bedbugs), and someone knows them as malicious pests of grain fields, flowers and seedlings (for example, a bedbug is a harmful turtle ). Some also have to endure their presence in their own house (bed bugs). But the fact that there are still water bugs (gladys, including giant ones), for many would be an opening. And this is not an isolated species, but a whole group of insects - Hydrocores, and it deserves special attention.
Generally speaking, bedbugs from different families are quite different from each other. Each insect is unique in its own way, but there are also truly extraordinary specimens. For example, some bugs that inhabit the water are also excellent flyers. How do they manage to exist at once in two elements - water and air?
So, meet - a water bug or gladysh.
Gladysha is not confused with anyone
Look close at the picture of the bug-gladice. He completely justifies his name:
His body, in fact, smooth and streamlined, resembles a boat, deftly and incredibly quickly dissecting the thickness of the water. There are a water bug and two powerful "paddles" - this is the rear pair of legs. They are much larger than the other limbs and carry elastic bristles. It's enough for a water bug to make a few strokes with the "oars" - and it has already moved a considerable distance.
This species of Semi-Hollywing prefers ponds with standing water. But it is not necessary to be near lakes or ponds to see this water bug, because gladysh settles in any puddle or in a barrel standing in the garden, and can even come to the veranda in the evening, attracted by the lamp's light.
A water bug is able to carry out quite a long flight. In the air, this insect rises at night, usually with one goal: to find a food-rich pond. The dense brown elytra and soft, membranous wings of transparent color serve as the basis for this important mission.
Attention is drawn to two large (by the standards of an insect) eye. From the penetrating gaze of a water predator, no one will escape.
Like all bugs, the gladysch has a piercing sucking mouthpiece. Overtaking the victim, the water bug grasps her forelegs, pierces her shell, injects a digestive enzyme during the bite, and sucks the juice out of it.

Water bugs can not be called silent. Gladysh-male is a real musician. He scratches the front pair of legs on his proboscis, making a sound like the chirring of grasshoppers.
Strange habits of the "water bee"
The bite of a water bug feels close to the bite of a bee. Therefore, the Germans came up with a gladysch very suitable for him a nickname - Wasserbiene, which means "water bee".
There is a bug-gladocha oddity, distinguishing it from other insects living in the water. Floating this water bug is not at all the way most insects do. A large creature with spread wings changes beyond recognition when it is in the water column.
When immersed, it turns over abdomen. It is this feature that helps representatives of the genus Notonecta to hunt. The water bug holds the surface of the pond under control, where it is easy to find small insects and their larvae.
But any predator, zazevavshis, often itself is a victim. So gladys can easily be eaten by a bird or fish. True, nature gave him the opportunity to avoid a fateful encounter with the enemy. The back of the water bug is light, which makes it invisible when viewed from the depth of the reservoir. Abdomen, on the contrary, is dark. Not every bird sees a water bug against the background of a dark bottom.
Eggs hides its bug gladysh safely. Groups of light-yellow, laid in a circle of eggs can be found in May on the bottom of the reservoir or attached to the bottom of the underwater plants. They ripen for two weeks, and when the water is warm - faster.
Larvae, similar to parents, are only lighter, during the summer they undergo four molts and reach sexual maturity. The chitinous cover, which remains after molting, repeats the outlines of the insect so precisely that it is easy to confuse it with a living individual.
With giant bugs, jokes are bad
Gladysh is capable of causing serious damage not only to insects, but may well become the culprit of the death of small fishes. What, then, is there to talk about giant water bugs, white-throated? They look menacing. Their powerful forelimbs resemble the claws of cancer and leave no hope that the prey can escape from the predator's dead grasp.
The impressive size of the giant water bug (more than 10 cm in length) allows him to attack the fairly large animals: frogs, turtles, fish. For the damage that water bugs inflict on the inhabitants of the reservoirs, they earned the glory of "fish killers".
Fortunately, on the territory of Russia this type of insects does not yet occur. Giant water bugs are a disaster for North America, Southeast Asia and South Africa. Similar insects were found in one of the lakes of Western Europe.
Belostomy is distinguished by a touching attitude towards the offspring, and the lion's share of cares for bearing children lies literally on the shoulders of the father: the female lays eggs directly on its elytra. Often, it can fit about a hundred future bedbugs. In the spring, the male, taking care of the younger generation, resembles a hedgehog

Thailand is famous for its special, unusual for European taste, cuisine. Thais could not help but pay attention to such a "tasty" piece, like a giant water bug. Fans of exotic can try these insects in fried form, and such a dish enjoys a good demand. Due to the attractiveness of giant bugs as a food product in some regions, their numbers have fallen dramatically.
Are meetings dangerous with water bugs?
Generally speaking, the usual "Russian" gladysh is not a very aggressive bug, and it is unlikely that a crazy idea to attack a person will come to mind. But when people, neglecting the elementary care, decide to take an insect in their hands, it will immediately respond with a burning sting that will be felt for a long time. From the bites of water bugs suffer mainly the most curious and fearless - children.
A giant water bug is also not inclined to hunt people, but it happens that bathers, bitten by a white-skinned, jump out of the water with a warped face.
However, most often a water bug when meeting a person acts wiser: he pretends to be lifeless or uses a technique typical of most bedbugs - throws out an odorous secret in order to scare off the enemy. Fortunately, the bites of water bugs are not dangerous to human life, although very painful.
On a note
Belostomy can harm people in a different way. In the early spring or autumn, when instincts force them to climb the wing, flocks of giant water bugs, moving at a decent speed, can bump into people walking by water. Anything pleasant these collisions do not promise.
No matter how formidable water bottles seem to us, do not be too afraid of them and even more so massively destroy them. Let's not forget that indefatigable gladyshes destroy in a day to hundreds of mosquito larvae. The likelihood of being attacked by mosquitoes is incommensurably higher than being bitten by gladysch.
And giant bugs are practically the only natural enemies of the three-keel turtles, which present a real threat to the juveniles of commercial fish. Any animal is part of the food chain, and each participant in it must deal with their business. Water bugs are not the animals that need to be scared and destroyed.
