This happened within 20 generations, making the “flatwing” crickets one of the fastest cases of evolution that has ever been documented in the wild. The newly silent males are undetectable to Ormia, but also to females. The silent males are reduced to loitering around the few males who can still sing, in the hopes of sneakily mating with approaching females. They also still go through the motions of singing, rubbing their wings together as if they could still thrrrrp away.
