In fact, it is almost certain to hear cricket calls in the summer, but extremely rare to hear them in winter. It has been observed, that crickets chirp faster in warm nights than in cold ones. Why Do Crickets Chirp More at Higher Temperatures? These sounds are sometimes used to warn the others of any danger that the cricket senses nearby. Crickets can chirp at frequencies of over 100 decibels, and such sounds can be used to startle or distract predators, enabling them to escape. They can make appear, as if their chirps are coming from somewhere else. To keep predators away at night, crickets have developed an amazing ability of ventriloquism. This is one of the reasons why crickets don’t chirp often during the day. Predators can often home in on the sound and eat the crickets.
This is a good strategy as crickets prefer to keep away from physical fights.ĭistracting Predators: Despite the usefulness of mating and territorial calls, being so loud comes at a cost. Territorial Warnings: While warning other males to leave their territory, the males use a different tone and frequency of chirping as opposed to the mating call. It is interesting to note that male crickets dig and live in underground shelters, with megaphone like entrances, which magnify and effectively spread the song to farther distances. However, the females are able to identify the chirp of the males from the same species, out of all the other males. There are around 900 species of crickets. Studies have shown that female crickets prefer fast and high-pitched chirps from younger males rather than the slow, low-pitched chirp of older ones. Similar to birds, the male cricket serenades the female, and the best chirping male usually gets the girl. Finally after successfully mating, the males will sing another song to keep the female nearby, and to keep her from mating with another male. This is followed by a softer courtship song after which the mating begins. Loud chirps from the males at night, help the females to locate them. Mating Song: Male crickets primarily use their chirping ability to create mating calls. The chirping sound of the cricket, is useful to it in many ways. Why Do Crickets Chirp?Ĭrickets are usually heard chirping at night, because they are largely nocturnal, and although you may also hear them during the day, such instances are much rarer. Let us now look at the purpose of such behavior. Female crickets do not chirp, as they do not have the same anatomy. This music can be produced with either wing, but research shows that most males prefer to use their right wings over the left. When these grooved sides of the wings are rubbed against each other, chirping sounds are produced. They also have a jagged edge above the grooves. The sides of their wings are grooved in texture. It is a common misconception that crickets use their legs to create chirping sounds. Not all species of crickets can chirp, and in those species which can, only males are capable of producing such sounds.
