Bees and wasps

There are at least 200 000 species of bees and wasps, in the USSR there are about 6500 species. Among them the most known domesticated (honey) bees, large wasps-hornets and some middle and small members of this family.
Bees live in large families, single-uterine - developed females, several hundred males-drones and several tens of thousands of bees. The role of the uterus confined to laying eggs. Worker bees take care of the uterus, nurture their young, build honeycomb wax, collect pollen, resinous selection of plants and flower nectar, process it in honey, cleaning their cells, harvested from hives waste, protect them from enemies and foes of the bees, bringing water to the hive, ventilate it in hot weather, prepare hives for the winter, hard cover cracks hives propolis. Bees are well oriented in space, clearly define the time of day; without cargo fly at a speed of 65 km/h, with load - 20-30 km/H.
Body bees covered with hard cover, consists of head, thorax and abdomen. In my mind focused senses and the nervous system, according to her sides large eyes, consisting of several thousands small peephole (facet), the crown three small, simple eyes. On a pair of antennae are the organs of smell and touch.
Two complex and three simple eyes bees distinguish the shape and color of the objects in the far distance and more clearly than the man. Thanks to the development of smell, they distinguish between the odorous substances in a dilution of 1 : 500, and some in a dilution of 1 : 100 000 000. It is difficult arranged proboscis lick in flowers drops of nectar. Legs consist of multiple segments, on the last 2 claw for walking on rough surfaces and pads for walking on slippery surfaces. On the rear legs are baskets for collecting pollen. The abdomen consists of 6 segments and 2 half-rings. Their flexible connection provides a reduction or increase of the volume of the abdomen, which is necessary for breath, collecting honey and nectar. Abdominal semirings posted vaskeviciene cancer.
Eat bee pollen and nectar. At the age of 3-5 days several times a day fly away from the hive, circling in the air, looking for young females, get acquainted with the location of hives and years, and on 7-10 day during the warmest hours do mating flights. Uterus 2-3 departure mates with 6-7 drones. Mating takes place when the ambient temperature is 28 degrees. Only the Queen has developed genitals. In her abdomen are two major ovary with 150 tubes, which are emerging and evolving eggs. The ripened egg is coming to the end of the tube and into a pair oviduct. At the transition to the single oviduct opens channels of samaryanka that stores the sperm entered by drones during mating. When postponement eggs in the cell in samaryanka allocated a drop of liquid with spermatozoa, which through a small hole penetrate the egg. One of them is fused with the core of the eggs, the other dissolve in the cytoplasm. From fertilized eggs develop in female mice (uterus and worker bees), male - drones developed when the deposition of eggs in the drone cells without fertilization.
Within 3 days from the egg is formed larva without legs and eyes. In the first days she swims in Royal jelly, rich in proteins, sugars, fat, mineral salts, vitamins, and enzymes. By the 5th day of mass larvae increases in 190 times by the end of the 6th day of its mass is 143 mg. During this period it several times shedding. On 5-6 days the larva does not fit in the cell, stop feeding and turns his head towards the exit. Bee seal its lid of a mixture of wax and pollen. Within 24 hours it spins a cocoon and after the last molt turns into a pupa with the beginnings bodies - the wings, legs, sting, head, chest and abdomen. On the 12th day it becomes an adult bee, gnaws the cell and out of her. The working bee is grown in 21 days, the grub - in 24 days.
Wasps, and bees are social way of life; build nests in holes in trees, often near habitation, in the walls of houses and so on, Some species are solitary. The social wasps and bees, strongly developed instinct of protection of the nests and the instinct of self-defense, which determines their potential danger for a person.
