“Why do crickets chirp?”, find out in this article. It serves as a means of communication for insects – and not just for reproduction.

Why do crickets chirp – the explanation

You can hear male crickets chirping with their wings, especially in the short period between the end of April and the end of June.

Male crickets chirp because they are breeding. The cricket plays the mating melody. This is usually relatively monotonous.
The cricket moves both wings against each other. On the upper wing there is the so-called “shrill vein”, which rubs against the thin ribs of the other wing, producing the typical chirping sound. The sound production is also called stridulation in specialist circles.
The male cricket can produce up to three melodies. If the female cricket likes the chirping, she mounts the male and mating takes place.
Male crickets can also chirp particularly loudly when they want to defend their territory.
If the chirping does not deter the other party, the two crickets fight each other with their mouthparts, the so-called mandibles.
The male starts chirping in the late morning, often late into the night.
The location of the concert is the burrow in which the cricket spends the winter. The burrow can be up to 20 cm long.

Crickets are similar to grasshoppers and belong to the order of long-fingered crickets.

Crickets have 6 legs and can “sing” surprisingly loudly.
The small animals can grow to a size of 0.5 to 5 cm.
There are approximately 1,500 different species of cricket.
The cricket’s large hind legs allow it to hop from one place to the next. They prefer warm and dry places.
They like to stay near houses and barns .

The chirping of crickets is an everyday sound in summer, but has an exciting scientific explanation:

Crickets are insects and like many other insects, they have a pair of wings. However, these wings are not like the wings of birds or bats, which are moved directly by muscles.
Instead, crickets have so-called “wing organs” that are moved by muscles connected to the thorax.
When a male cricket chirps, it moves its vibrissae rapidly back and forth. This creates a sound wave that travels through the air and can be heard by other crickets. Female crickets hear the chirping and can thus determine the location of the male.
The louder and faster the chirping, the more attractive the male is to the female;
When it gets warmer, crickets can chirp faster because their muscles work faster. When it gets cooler, they chirp more slowly or stop altogether.
All in all, the chirping of crickets is a fascinating phenomenon based on the science of insect behavior. So the next time you hear crickets chirping, remember that it’s an important mating behavior based on science.
