You probably think you know what cricket is. Most people in the United States are familiar with crickets, and most have noticed that they chirp at night. But why do they chirp at night? Is it just because it's dark out? Do they need light to see? What happens during the daytime that causes them not to chirp during the day but only at night? There are many explanations for this phenomenon. Some say that crickets don't like sunlight so much, while others believe that their song helps keep other insects away from their territory. I've also heard some experts speculate that these nighttime sounds help attract mates or warn predators of their toxicity, ensuring a haven for themselves and their eggs. So what is causing these?

Introduction to Crickets

Crickets belong to the order Orthoptera and the suborder Ensifera (long-horned grasshoppers), which make up one of the largest groups in the class Insecta (insects). All crickets have abdominal "horns" called tympana, sound amplifying chambers containing tiny drumhead membranes. These organs allow crickets to hear high-frequency noises that human ears cannot detect.

Cricket is usually found in sunny areas. His favorite environments include wasteland, natural meadows, pastures, roadsides, heather moorland. Occasionally, it frequents our lawns under which it digs a deep burrow (10 to 30 cm long) where it takes refuge in bad weather or when it is frightened. This is where he spends the winter, sheltered from the cold, and patiently awaits the return of sunny days.

Cricket is a single person who assumes responsibility! We never see two congeners in the same hole, if not of the opposite sex, and only furtively during the mating season. His solitary character translates into a hot temper that leads him to confront anyone who dares to break into his burrow. Its territory defense can lead to fierce duels, often resulting in reciprocal mutilation or even an adversary's death. 

The Sound of a Cricket Chirping

Crickets are nocturnal insects, meaning that crickets can be seen or heard only at night. Crickets produce a distinctive song by using their wings to create sound waves. During the day, crickets remain hidden under rocks, leaves, and building foundations where they rest until evening. When it is dark, outside crickets begin making their characteristic chirp, which is sometimes called singing because of its similarity to human singing. The male cricket produces his song by rubbing his modified forewings (called file-like tegmina) with one wing covered in tiny spines (antennae) while the other remains silent. This creates a shrill sound similar to fingernails scraping across a chalkboard. The male chirp is a mating call to attract female crickets.

The females do not create songs but can sense the males' chirps through their antennae. Females respond to the male cricket by walking or flying in the direction of their calling. During this process, called phonotaxis, they use pheromones (chemical scents) from their wings as guides to find a mate. Once a female finds a male, she deposits her eggs onto his back; he then fertilizes them and carries them for about 14 days before dropping them into the soil, where they will hatch after 7 to 10 days. The newborn crickets will remain underground for a couple of weeks while molting and growing until it is time to migrate above ground.

Crickets are one of the unique things used to mark the arrival of the dry season. In addition, there are several reasons why the sound of crickets is heard at night. 

3 Reasons Why Do Crickets Chirp at Night:  

1. To Mark Their Territory

Each animal has the privilege of marking its territory. Some animals mark with claws, urine and also make sounds. For example, crickets mark their territory with sound, and only male crickets make sounds while females do not.

2. To Attract Females

The sound of male crickets is also used to find a mate in addition to guarding the territory. However, the sound that comes out is different. That's why the sound of crickets is often heard at night.

3. To Fight Between Crickets

Male crickets, when fighting in addition to crashing their heads, will also make a distinctive sound. The crickets will stop making noise when they give up.
