Parasitism of fleas on humans since ancient times to modern times was probably as commonplace as epiclesis. However, lice (if people are generally bestowed them with their attention) were considered as something vile and repulsive, the flea, on the contrary, in many cases, summoned the interest of collectors, and even served as the subject of extravagant entertainment rights.

That is one of those pastimes. In the 17 Th century among the French cavalry was fashionable to keep as a sweet memory, a flea caught by his own hand on the body of the women of his heart. Holding a flea in miniature, often-beautiful jewel box of a cage hanging on a chain around his neck. And flea every day sucked the blood "happy" owner. This, incredibly kind souvenir, the original was trying to attract the attention of others and only was with him entree into dubious company. In addition, when the flea dies, heartbroken Cavalier went to catch a new souvenir for the participation of all living dissolute monks.

The eggs mature at the same time only a part of egg tubes ovary and deposited alternately in small clutches at short intervals. Females of different species doing a day 1 - 4 of masonry on the 2 - 13 egg each. The rate of maturation and egg lying depends on temperature and other environmental conditions. During the life of one female can lay up to 500 eggs.

By the nature of their parasitism of fleas represent different transitions between the nest, on the one hand, and these parasites - on the other. They are never far removed from the host or its nest. In those cases where, for their way of life master relatively few associated with the socket, the fleas are forced to spend most of their time on the host. Thus, the image of the flea life can be divided into two main groups: the nest fleas and flea fur.
