A new study carried out by an international team of researchers led by the University of Bristol (United Kingdom) has discovered that male crickets use their repetitive singing to attract potential partners, so that the more energetic the trova, is greater the size of the cricket. In this case the tenors not makes them lack tuning throat: simply rub their wings making that they produce a resonant and intense vibration. Somehow, the message emitted is: I’m here and I’m big. The sound serves to make females find males and allows them to discern whether it is an individual of great size. In this case size does matter because larger males are better when looking for resources in nature. But the singing not only depends on the size.

Tiny, almost transparent and very scarce tree crickets, are able to change the tone of your voice with the temperature. One species, elOecanthus henryi, sings with a sharp, squeaky tone 3.6 kilohertz (kHz) when the temperature is 27 degrees centigrade, while that same song becomes a deep serious 2.3 kHz if the temperature is 18 degrees. Natasha Mhatre and his colleagues have come to the conclusion that as the wings of these insects are lengthened, the frequency and the amplitude of the different modes of vibration are approaching and begin to merge among themselves. The frequency of the singing of these animals is not related with its size, but with the speed at which tree Cricket is able to move the wings. As published today in the journal PNAS, since it’s cold-blooded animals, temperature influences their activity, so that they have more energy and sing faster and at a higher frequency as the temperature increases. Therefore, the song of the cricket also contains meteorological information: is much sharper, more heat makes. movies, documentaries, concerts, comletos. Articles science, health and nature.
