Crickets are notorious for chirping nonstop in the evenings. Only males have this ability, and the sounds indicate they are trying to attract a mate. They chirp through a process called stridulation, rubbing the edges of their front wings together to create the familiar chirping sound.
While some find this soothing, constant chirping at night can be bothersome for those trying to sleep. Crickets stop when they detect a threat, which is why they go silent when ground vibrations approach. This makes locating them difficult.
