Name: The field cricket Teleogryllus oceanicus.
Some Sing Males attract females by rubbing their forewings together to chirp. Males who can’t or don’t “sing” lurk near singers to mate with lured females.
Who Listens? Females do, for sure—but so do juvenile males, note biologists at the University of California at Riverside.
What Happens? Males who grow up amid lots of singers tend to have bigger testes than those who don’t. They’re in better physical condition and more likely to sing. The study shows that insects’ behavior and bodies are keenly attuned to their social environments.
