By modulating wing beat frequency, and thus light flash frequency, the flies effectively communicate to their peers their sex, age, and possibly even mating status.

Here, we show that there were no significant relationships between type of marriage and the total number of alive children and number of dead children among the three sampled groups.

The presented study is the first to date to examine the fitness benefits of free mate choice in humans.

According to the researchers, the ability to distinguish between different light flash frequencies suggests that green bottle flies have numerical competence even approaching the level of mammals, birds and fish.

In this study, the researchers mounted two live females side by side; only one had fully functional wings, while the other’s wings were immobilized.

Thus, between-mate behavioral compatibility may be evolutionarily significant in birds.The video recordings revealed that light flashes were not evident under diffuse light or outdoors under a cloudy sky. Gries adds: “We found that on cloudy days, light flashes from the wings of flying females cannot be seen, which might help explain the low mating activity of these flies on cloudy days.This suggests that flies can apparently synchronize sexual communication with environmental conditions to optimize the conspicuousness of their sexual communication signals.” Male flies were also found to be attracted to LEDs that pulsed light at a frequency that imitates the wing flash frequency of prospective mates, suggesting that it is light flash frequency, rather than the morphological characteristics of the female flies that forms the mate recognition signal.We use cookies to make interactions with our website easy and meaningful, to better understand the use of our services, and to tailor advertising.
