To hide themselves from deadly flies, crickets on two Hawaiian islands have evolved an inability to sing.

Ten years ago, two years apart, males appeared on Kauai and Oahu with altered wings, which they would normally rub together to chirp and attract females.

New findings published in the journal Current Biology show that the wing changes are physically different and arose from separate mutations.

Evolution is always working.

Just wondering, how did their intraspecific relationships changed ?
