The “lazy” males of wild bees took on additional responsibilities, but only to get more chances of mating.
Drone is a synonym of idleness and uselessness at work: the few male bees do not take virtually no part in the life of the hive and care for the offspring. But a new study of red-listed bee-certain (Ceratina nigrolabiata) found their first case almost full of work, which included drones, reports the Chronicle.info with reference to naked-science.ru.
Female ceratin gnaw through tunnels in the roots of plants, arranging them in the nest. Unlike normal honey bees, they are loners and self-collect nectar, preparing all the necessary for hatching and rearing. During absences, the females nest is left unattended and the males are already going around. Czech biologists led by Jakub Straka (Jakub Straka) observed nests of ceratin in the wild, in the national Park of Bodie. This researchers write in an article published in the journal Proceedings of the National Academy of Sciences.
Scientists have noticed that male plug the nest entrance and hold it for more than hours, putting out only the rear part of the body. However, they experienced a 41 attack of predatory insects, and more than half of the cases did not allow them to get inside. Each time you return to the female rubbed the abdomen of the male, and he stepped aside, passing it, and then again became “on guard”.
This behavior of the drones have evolved not from a great love for the work. Scientists believe that it increases their chances to impregnate a female and pass on their genes to the next generation. Atiras about female while she is building a nest and lays eggs, the male gets a lot of opportunities for fertilization, which have certain can occur at different stages of life. Loyalty to the beloved bee drones also don’t need to keep from time to time, change the socket to enhanced opportunities to leave offspring.
