On the surface of puddles, rivers and other bodies of water, you can see insects that quickly glide along the very surface on long legs. These are water bugs, a whole group belonging to the order of bugs.
They are safe for people, but it is not recommended to touch them, since they will be rather painful bites to defend themselves. Bed bugs feed on small insects, and large individuals feed on fish, some of the subspecies can fly. However, they do this solely for the sake of changing their habitat.
The family of water bugs includes six varieties, and they are not similar to each other. They have body size from 2 mm to 12 cm. They lead an exclusively aquatic lifestyle, and all are predators. The most famous water bugs are water striders and smoothies.
Bug water strider
Exists about 700 varieties of water strider bugs, which differ from each other in color and size. This insect has a long elongated body, which can be from 1 mm to 3 cm. Three pairs of legs extend from it. The front ones are short, necessary for capturing prey and regulating the speed of movement. The middle and hind legs are used for locomotion and have a length of 1.5-2 times largethan the body of a water strider.
Why do water strider bugs not drown, but run along the surface of the water? Insects are held on the surface of the water due to the force of its tension. On the head of the bug there are special antennae that can catch even the weakest vibrations of the water surface. The oral apparatus is piercing-sucking, and is used to suck out the contents of the victim.
REFERENCE! Some of the subspecies of water striders have wings, and they use them to move between ponds. They can temporarily settle on the surfaces of puddles. Wingless individuals spend their entire life in the same reservoir.
Water strider eggs are laid on the leaves and stems of aquatic plants. Sometimes they are located singly, but usually in groups of 40-50 pieces. The larva looks like an adult, but differs in a small barrel-shaped body and small size.
The water strider settles in bodies of stagnant water or rivers with very little flow.
Who eats water strider bugs and what does he eat? He can set up an ambush at the very edge of the water. It feeds on invertebrates, insects, fish fry. Thanks to its large eyes, the water strider is able to notice prey from a distance and attack it with its proboscis. They themselves become food for large fish.

The bug is smooth
The bedbug has a smooth streamlined body, thanks to which the insect got its name. The rear pair of legs is much larger than the rest, and is used as "paddles" when moving on water.
Gladysh loves stagnant bodies of water, but very often it settles in any puddle or even a barrel of water. He can make long flights exclusively at night to find a new place with food. Like all other bugs, the smoothie has a piercing-sucking mouth apparatus, with the help of which it pierces the victim's body and sucks out nutrients.
REFERENCE! The smoothbug can be called a musician - it can rub its forepaws on the proboscis, emitting a kind of chirping.
What does the smooth bug and its respiratory organ breathe? In water, the insect turns upside down, sliding along it on a smooth shell. In this position, the smoothie breathes simple atmospheric air, which it receives through special holes located in the back of the abdomen. During diving, the insect gains the necessary supply of air, after which they are closed with special plates.
Gladysh preys on insects or small fish. At the same time, he himself can be the prey of fish or birds. However, nature has endowed with protection from these predators - his back is light, and his belly is dark.
The bug lays eggs on the bottom or underwater part of the plant. After 2 weeks, larvae appear from them, similar to adults, but lighter in color.
The smoothie does not attack a person, and usually when he meets him, he pretends to be dead or throws out an odorous protective liquid. However, when you try to pick it up, you can get a painful bite that will hurt for a very long time, and sometimes even fester.
Water bugs are a whole family that lives exclusively in stagnant bodies of water or rivers with weak currents. They are predators, have a piercing-sucking apparatus, with the help of which they suck the juices from the prey. Some species have wings with which they can fly to find a new place of residence. Water bugs do not attack people but can sting for protection, causing painful bites. The most famous are the water strider and the smoothie.
