Male flies cheating with fake gifts

Like in many species of insects and animals, including humans, people like to receive gifts from men who pursue, but there has been a study that shows that male flies often seduce her with meaningless fake gifts. .

The con artists in the animal world can easily get the girls into the trap to create a race that carries their own genes.

Scientists have explored the dancing fly Rhamphomyia sulcata . The male of this fly often has to give her attractive dishes, like a delicious big bug, to get her "grace".

To find out if these spoiled girls are easy to get trapped, scientists have replaced real gifts with pieces of bug or bun-like berries that deceitful men often give to their children. .

"Male flies often cheat with beads, balls of silk or leaves or twigs," said Natasha LeBas at the University of Western Australia.

In this case, the time when the female flies takes the test and tries to eat the cotton long enough for the male to penetrate her.

The researchers also found a link between the size and quality of the gift and the time of sex. Really impressive gifts will lead to a longer "love" time. Time decreases with real but small gifts, followed by symbolic gifts and ultimately small, meaningless objects.

A pair of flies "act" on the leaves while the gift-giving girl is a delicious bug.

The male enlisted "the action" while she tried to chew on the boll.

If the children do not yet hold the gift, she immediately stops the fun and chases him.

LeBas explains that deception by symbolic gifts has little effect on the breed, but it reveals the war between the two factions in the way that males and females invest in reproduction.

"Every faction wants to invest less and get more. This study is an example of a species in which males, which have to invest heavily in nutritional gifts, have found a way to work. more fruitful with a gift, because the children will take some time to test that fake dish. "

Steven Heydon, a senior scientist at the Bohart Museum of Entomology at the University of California, commented: "Insects need to go out and hunt, so it will become a target for other predators. If you are an insect out looking for bait, chances are another bird will hunt you down too, by giving you fake gifts, the male will have a better chance of making love, because they will last longer. " .

Heydon said some flies also gave their partners an empty box of silk. "When the children opened the gift and found it empty, the guy also solved her".
