Sex Can Be Very Dangerous For Flies

From diseases to pregnancy to hurt feelings, a lot of negative things can happen after a random sexual encounter between two human beings. Luckily, being attacked by a predator isn’t often one of them. Flies, on the other hand, well, they apparently take a big risk when they try to mate.

Researchers at the Max Planck Institute for Orinthology in Seewiesen, Germany have just released the results of a new study in which they found the copulation of flies produces a noise that attracts hungry bats. At night, the flies who stayed still and didn’t engage in any extracurricular sexual fly activities reportedly were almost never attacked, but those who found a sexual partner were attacked fifty-nine out of one thousand one hundred and five times. That might not sound like a high percentage, but given both flies died in almost every attack, it’s probably a pretty important difference to them.

According to The Los Angeles Times, the researchers at first hypothesized that the increased size could be attracting the bats; so, decoy models in sexual positions were placed around the room. The fakes were never attacked, but later, when fly copulation noises were played through speakers, the bats attacked the speakers.

Considering their inability to read and their desire to keep making little flies, it’s unlikely this study will have any impact on fly behavior. More than likely, they’ll keep dying the same way Scorpios do in Chris Rock’s “No Sex (In The Champagne Room): fucking.
