Cricket Chirps Potentially Have ‘Predatory Roots”
Scientists have discovered that some cricket’s chirps could be a technique to reveal their location to potential mates.
Researchers say that the mating call has likely evolved from the males impersonating hunting bats. The call triggers the female cricket to shudder and in turn allowing the male to locate the female. Learn more about the findings here.
“It struck me as very strange that these crickets would use such high frequencies for mating purposes,” the scientists at Dartmouth College said, especially considering that other cricket species avoid sounds at these frequencies.
Lead researcher Professor Hannah ter Hofstede said, “I expected the females to walk to the speaker, because this is the usual behavior for female crickets, but they did not do this – [they instead] made a small jerking motion after each male call.”
Further study revealed that this way of communication has changed over evolutionary time to be where it is at today.
