Cockroaches entice females demonstration "muscles"
In order to attract a female, the males Antillean cockroach (Byrsotria fumigata) perform a kind of ritual, demonstrates "bulging biceps."
According to Sci-news, to attract the attention of a future partner, West Indian cockroaches begin to flap their wings vigorously. According to a study carried out the Dr. Sophie Moules from the University of Nottingham, the males with the most vigorous movements had a greater chance of success than their sluggish cousins. And a show of force for the females was even more important than the size of the male.
"Signs of male stamina is definitely important for females as it should be passed on to offspring good genes, so they avoided death and after, in turn, attracted good females" - summarized Dr. Moules.
As an example, a similar ritual among other fauna she brought the Sword-fish Xiphophorus sp., Which the males during courtship actively waving their large tails - this also requires a lot of energy. There is a similar ritual and wolf spiders of the family araneomorphae. To attract females they begin intensive stomping legs - "to play the drum."
Earlier, the scientists also found that cockroaches emit specific "pheromones". The fragrance that is created by intestinal microflora of insects and secreted with feces, cockroaches forces to come together.
The expert explained why cats are upset
The expert explained why cats are so fond of upsetting things. This habit of pets, I must say, irritates many owners.
Its conclusions on this matter presented a well-known veterinarian Eric Douteri (Dr. Eric Doughtery). Previously, it was believed that cats causes upsetting things instinct. "Victims" are often the cups, saucers and pots of flowers. Ostensibly, this is how the animals hone their skills. However, according to Douteri, this conclusion is incorrect, because cats prey on small and moving objects, rather than stationary.
But what is the reason for such behavior of pets? The expert believes that in this way the cat wants to attract the attention of the owner. Tell him that she is hungry or experiencing health problems. And animals do so when nervous. And to break the peace of mind of a pet can be any change of situation to which he was accustomed.
It would be unreasonable to demand from the cats 'ideal' behavior. "In contrast to the cows and dogs that we have domesticated cats domesticated themselves. They do not need people to survive, "- said Eric Douteri. In order to avoid the destruction of valuable objects, he advises to arrange for pet quiet secluded area.
Previously, we recall, another group of researchers found that the freedom-loving nature of dogs and their love of solitude due to the fact that people do not associate these animals to safety. The experiment showed that being in a strange place, a cat does not count on the owner and can not see in it the guarantor of its security.
