Honeybees to transfer pollen from flowers to the hive using the hairs on his body, which grow even


If a person as a result of surgery, trauma, or congenital abnormality no lens, he is able to perceive mode glamour ultraviolet radiation in the form of a whitish or whitish-blue-purple color. However, this is not the same as that currently tetrahromatizm you have many birds, fish and insects. With this vision mode glamour in the eye in addition to the three normal cone is the fourth, just perceiving ultraviolet spectrum, whereby the number of distinct shades of colors are much higher.
Honeybees to transfer pollen from flowers to the hive using the hairs on his body, which grow even eyes. Bees, like many other insects, complex compound eyes. Of the gaps between the components of their eyes and hair grow.
Argentine ant - an invasive species, originally living in the South American Parana River basin, but then due to unintentional human involvement spread across continents. Currently there are three of these ants supercolonies: on the west coast of Japan, on the California coast length of 900 km, and the largest in Europe - 6000 km along the coast of the Mediterranean Sea. And in fact, they are one of the global mode glamour supercolonies as any Argentine ant anthill anthill from another any part of the world was mistaken for his.
Bees during flight due to the friction of the air on the body hairs accumulate a positive charge, and the flowers usually mode glamour have a negative charge. It has long been known that due to this difference pollen from flower literally flies on the body of the bee. But recent experiments helped mode glamour reveal that bees and bumble bees can extract mode glamour the characteristics of the electric fields useful information. For example, a modified mode glamour field plants after a visit one bee can tell another that a new portion of the nectar in the flower yet.
Australian mode glamour species Cryptotermes secundus termites live in colonies of 50-100 mode glamour individuals, headed by the "king" and "queen" - only this couple engaged in reproduction. When the main termite dies, several working individuals claiming the championship. Sometimes they find out the relationship direct conflict, and the losers in the battle other termites eat. However, most often a struggle for power is much more peacefully: contenders for the throne act in the manner of politicians meet with voters, spending a lot of time on contact with ordinary workers mode glamour mustache termites and feeding them with additional mode glamour portions of food. Eventually, a new colony of the Royal selects a pair with a minimum number of victims.
The structure of the hind legs of larvae of leafhoppers species Issus coleoptratus mode glamour found growths that form the gear. "Gear" on each limb consists of 12 teeth - at the moment of the jump insect these structures are concatenated and are turned, thus synchronizing repulsion feet from the surface. The difference in the start time of foot traffic does not exceed 30 microseconds, and this accuracy would be impossible to achieve if the synchronization of the control through the nervous system neurons. In adults, these leafhoppers gears disappear.
For a long time scientists did not know whether to keep insects with complete metamorphosis any memories of previous stages. In 2008, researchers at Georgetown University, conducted an experiment with hawk moth - they hit caterpillars electric discharge when a certain smell. When the caterpillars become butterflies, they avoided the smell. Was installed and temporal separation - if caterpillars trained under three weeks, they are not the butterfly stage towards mode glamour the scent. The researchers concluded that the butterfly preserve the memory only if the nervous system caterpillar reaches a certain maturity.
South American monkey species mourning capuchins are able to use natural repellents mode glamour against mosquitoes. They are found in the bark of trees millipedes that secrete protective chemicals class benzoquinones, and rub their skin.
Reproduction of aphids mainly mode glamour occurs through parthenogenesis and live birth. In many species of aphids babies are born pregnant, that is, the egg begins to develop inside the mother before the moment of birth of the mother, and after 10-14 days comes a new aphid.
One of the species of flies skorpionovyh, Hylobittacus apicalis, described entertaining marriage. For mating, the male must present a gift to the female booty, and more booty, the more likely the beginning of mating. Female eats prey in the process, and if the food is still not very much, the pairing is completed mode glamour before the moment of insemination. Males sometimes do not produce their own sacrifice and steal it from mating pairs. Some males are more subtly - by seeing another male with prey, they fly up to him and perform typical movement females before mating, often getting "wedding gift" and fly away with him to look for his female.
