How many bees wings, their structure

How many wings do bees? Perhaps this is the question people are asking because the fear to take up honey insect. In the following detailed description of the structure of the aircraft bee and its features.

Education wings

The Development of the wings of bees starts at the pupal stage. The original appearance of the rudiments in the form of bags can be seen on the side wall of the mesothorax and the metathorax. Surprisingly, tumors connected with the cavity of the body, distinguished by the presence of the trachea, nerve branches and blood. The structure of the protuberances are the epidermal cells forming on the front side of the soft cuticle that hardens as they grow older bees. The end stage of formation of the wings occurs only after the liberation from the puppet shell. Under the influence of blood flow protrusions are straightened and take the form of a bifurcated plate. Subsequently, the wings converge and coalesce.

This process allows you to determine how many pairs of wings bees. As the insect produces two double plates, it is possible to say that they two pairs. Front and larger rear, but the structure is the same. At first glance, elastic double plate seems fragile and weak. In fact, it is not. The strength they impart to the veins, which is a hollow rigid tube. During development there takes place a discharge of lymph, which, strictly speaking, spreading her wings. Under the microscope the surface of the wing, you may notice short hairs, although it seems smooth. To better understand what the wings of bees, you need to consider in detail their structure.

Ribs

The Venation of the wing forms a powerful framework of transverse and longitudinal hollow tubes. The first of them branch out and connect with the second. The void between them filled with the transparent membranes. Interestingly, the veins are not arranged randomly. Depending on the location, each of them has its own name and purpose. For example, from center there are 4 longitudinal tubes: medial, subcosta, bone and anal. In addition to them, jilkova network contains such tubular formation, radial and cubital discipline that complete cell. Due to this structure, in the wings throughout the life of bees occurring metabolic processes. Moreover, it combines two required properties-strength and lightness.

Support

The pivot point for the wings is a column-planet. From his outside shoulder leaves long. In the area of attachment of the segment to the membrane is the point from which the column of stacked short shoulder. When the back begins to shift, flying disc bee lifted. Due to the fact that the hollow tubes do not reach the edge, it produces vibrations.

A Significant role in the movement of the wings play the articular disc. They attach to the wings flexibility, strengthen their foothold, and provide liveliness to the tips of the veins. In the wings of a bee muscles are absent, so the movement they lead the muscles of the thoracic region of the body.

Muscle

For the basic functioning of the aircraft meet the dorso-ventral muscles and longitudinal muscles of the back. They coordinate and set the correct direction of flight, providing the wings with their energy. They are called indirect muscles because they are not attached directly to the base plates. While reducing the vertical muscle is drawn tergite, causing the wings located on the opposite side, begin to rise. The contraction of longitudinal muscles causes the caterpillars to bend, and the plate is lowered. Longitudinal bends are made at the expense of the muscles that perform a secondary role in the flight of bees, but have a direct effect.

Wings

Double wings pinned to the breast cups. In the initial position they are stacked along the back (fully cover the front back) and begin to deal directly before the flight. If we talk about how many wings do bees responsible for the lift force, the two of them. In the aircraft of the insect, a large load when lifting and flight goes to the front of the plate. They have the clips with which they cling to the back pair of wings, which are endowed with special hooks.

How many wings do bees performing the steering function? Two rear wing during flight adjust the direction of the insect. Thanks to this feature it is successfully deployed, and makes all necessary movement.

For a second the bee performs about 350 strokes. The scale they have is quite wide, because the wings barely touch each other on the back and almost clinging on the lower limbs.

The Amount of nectar brought usually depends on the distance of travel of the insect. The further it flies, the less will be his prey. The average honey plants cover approximately 7 km away.

The bees-toilers of flying plate very quickly wear out. It is possible to determine the age of the insect and his family.

Purpose

So, how many wings do bees, we found out, now let's see what theyshe needs.

• The Wings of bees, primarily intended to move it. Melliferous insects need time to collect nectar.
• Ventilation. Fluttering while in the hive, bees carry out the ventilation of your home, protecting it from excessive moisture. This is especially important when collecting nectar in hot weather.
• With the help of their lamellar outgrowths of melliferous insects are cleaning house, vymetaya the garbage.
• The Wings of the bees need for the release of special enzymes.
• The Hum and buzz of insects also arise due to the presence and work of the wings. With their help, the insects emit lights and sounds with different shades. Experienced beekeepers use this ability insects in their practice. The sound of LPS you can define whether to return the bee to the extraction, or is it a flying drone.

Movement of hemolymph

How is the movement of hemolymph in the hollow tubes of the wings, for many scientists, it remains a mystery. Observation of experienced specialists introduced some clarity in how this process occurs. According to them, subtotalna costal margin and veins are the carriers of hemolymph towards the periphery. Anal and discoidal the tubes is carried out by the outflow, and the liquid is returned.

The Circulation of hemolymph is maintained by reducing the pulsating organ located in the thoracic region of the body. The continuous process of movement contributes to the functioning of the trachea, located in subcostal tube. Its participation is caused by the ability to periodically compress and straighten up. The results showed that part of the outflow of fluid takes place in this vein. Passing through the ventral region of the trachea subcostal tube, hemolymph flows in the radial part of the plate, then distally and ends its cycle at the same point. On the way back to the hemolymph passes through the dorsal region of the trachea and the tube in the radial misses.

Nervous system

The Structure of the wing of a bee is a rather complex construction, which also implies the presence of nerves. The coordinated work of the body of the insect provides the so-called “station”, which unites all the bodies into one. The role of the organizer carries out the nervous system. It is divided into three parts: Central, autonomic and peripheral. Last nerve chain of the bee is the abdomen. From it nerves branch off to muscles, the sting glands and other organs located outside. From nodes located closer to the chest cavity, the nerves depart to the legs and wings.

Bees

Not all insects make sounds during flight. For example, the butterflies make their journey quite quietly, “propeller” some beetles at medium volume. What is the secret to a strong buzz bees?

It All depends on the speed and number of strokes of the wings. The important role played by the size of the aircraft records. Insects with large wings, rarely perform Mahi, and therefore their flight is silent. As seen in the photo, the wings of the bee in relation to her small body. To stay in the air, the insect moves them with great speed, which creates the buzzing.

The Sounds produced by the wings, help the bees to communicate with each other. Therefore, they convey information and warn of impending danger.

In conclusion

On closer examination of the structure of the melliferous insect in question "how many wings do bees" the answer will be unequivocal-4. The device of the aircraft of these insects really unique, but it represents just one facet in the complex structure of the bee body. Experienced beekeepers know how interesting it is to observe the behavior of these individuals.
