What Are Crickets

What Are Crickets

Crickets are insects. They have long antennae. They have an exoskeleton. They hear with an organ on their front legs. They breathe through holes along their sides. Most crickets have four wings, but they almost never fly. They are also among the best jumpers in the animal world.

What Are Crickets
Cricket Insect

Insects can be divided into about thirty groups. The crickets and grasshoppers make up one Of the Oldest groups called the Orthoptera which means “straight-winged.” There are over 17.000 types of crickets and grasshoppers in the world. Almost all of them live in warm. sunny countries.

Baby Crickets

Baby crickets are called nymphs. They look like small adult crickets. Crickets molt several times as they grow. The new exoskeleton is soft and pale. It hardens and gets darker as it dries.

Where Do Crickets Live

Crickets live in many places. Some live under logs and rocks. Some live in burrows. Others live in cracks in the ground. Some crickets live in houses. Others live in trees. They like damp places.

What Do Cricket Eat

Crickets eat many different things. They feed on small plants. They feed on other insects. They eat garbage. They eat fruit. Many crickets are nocturnal. They feed at night.

Do Crickets Sing

No, they do not. They make a chirping sound by rubbing their front wings together Male crickets chirp to find a mate. Each cricket has its own chirp. Some crickets make holes in leaves. The holes make their chirps sound louder. Crickets chirp faster as the weather gets warmer.

People have always had a special affection for crickets. Some have been made famous in literature. including the house cricket in Charles Dickens’ Cricket on the Hearth. and the talking cricket in the story of Pinocchio.

Anatomy of a Cricket

Anatomy of Crickets: Crickets and grasshoppers are found all over the world. By looking at their shapes we can tell that they are insects. Their bodies are divided into three main parts: the head is the smallest part and is found at the front end. The middle part is called the thorax. and it holds the three pairs Of legs and two pairs Of wings. The largest section is called the abdomen This is often hidden under the wings. The bodies of crickets are made of a hard. light material called chitin (kite-in). This forms a tough “skin” or “shell.” which acts as a skeleton and gives the insect its shape. Insects do not have bones’ inside their bodies.

Crickets have long, narrow bodies. All have rounded heads and squarish thoraxes. The head holds the eyes. a pair of “feelers,” or antennae. and a largemouth. Every cricket has a pair of large eyes on its head. These are called compound eyes because they are made up of many tiny parts. each of which sees only a fraction of the overall picture. Their compound eyes can also see colors. Many crickets and grasshoppers have two or three tiny, simple eyes on top of the head too. These cannot see a “picture,” but can tell night from day.

The thorax is covered by a large plate. or shield, which is called a pronotum. This acts like armor in protecting the top of the thorax. It also covers the back of the head and base of the wings. All crickets have two pairs of short legs and one pair of huge, back legs. Most grasshoppers, and some kinds of crickets. have two pairs of long wings. The straight. leathery pair Of front wings usually covers the finer. more delicate back pair. The hind wings are much bigger than the front. and are kept folded when not being used to fly Other crickets and grasshoppers have very short wings.

The abdomen is made up of ten rings. or segments. of hard armor. These segments help the insect to bend its abdomen while still protecting the inside Of the body. The abdomen contains the gut and special parts that make eggs and sperm cells.

Crickets usually have long antennae. often longer than their bodies. and short wings. Some kinds have such short wings that they cannot fly. The female cricket has a long. pointed “sword” sticking out from the end of her abdomen. This is called an ovipositor and is used to squeeze eggs into cracks and crevices.

Common Cricket Species

Field Cricket

Field crickets live in burrows. They use their back legs to dig into the ground. As they dig. they use their back legs to kick soil out of the hole.

Mole Cricket

Mole crickets are odd-shaped brown crickets that burrow underground. They dig with their front legs, which are like big, clawed spades The bodies of many kinds are covered with fine hairs. They are present in many parts of the world and is often a pest in fields of root crops.

Camel Cricket

The North American cave or camel cricket is a wingless, humpbacked cricket that lives under stones or in caves during the day. It comes out at night to hunt for small and often dead insects and is unusual because it cannot sing, and has no ears.

Dune Cricket

By day, the dune cricket stays in an underground burrow in the hot, dry Namib Desert. It only comes out at night, when the air is cooler. The dune cricket hind feet are flat lobes fringed with hairs. They keep it from sinking into the sand.

Cooloola Monster

In 1976 a new kind Of cricket was discovered in Queensland, Australia. Its appearance is so strange that it was called the Cooloola monster. It lives underground, Only the males come to the surface after rain at night.

Life Cycle

Males chirps during the mating season in order to attract females and to let the females know where they are located. Crickets go through three stages of the life cycle: egg, nymph and adult.

After mating with a male, the female cricket lays her eggs in humid soil using their ovipositor. The female cricket has a tubular organ called ovipositor at the end of the abdomen by which eggs are deposited. The female cricket deposits between 50 and 100 eggs into the soil, usually about half an inch deep. After about 14 days, a tiny cricket nymph hatches from an egg.


Nymphs look like a tiny version of adult crickets. The main difference is that it has no wings and the female does have an ovipositor. Nymphs go through 8 to 10 skin changes. This process is called molting. A nymph starts to develop wings at about 1 month of age.


In about 45 days, the small crickets get to adult size. Its wings are fully developed. The primary goal of adult cricket is to eat and reproduce. Adults generally live between two to three months.


Male crickets are the only ones that chirp. Male crickets chirp to find a mate. The cricket’s chirping sound does not come from his mouth, but from his raised wings. Male crickets make a chirping sound by rubbing their front wings together. One wing has a hard, ridged vein. which we call a file. The other wing has a hard ridge which is called a scraper. By quickly rubbing the scraper across the file a sound is made. Every type of cricket has a different song.

Crickets are usually silent when the temperature falls below 55 degrees Fahrenheit. When they are making their music they vary its regularity and pitch according to the weather. Spowy tree cricket speeds up or slow down intervals between chirps with the rise or fall of the thermometer.why he is sometimes called the temperature cricket.

Dolbear’s law

Dolbear’s law states the relationship between the air temperature and the rate at which crickets chirp.
It was formulated by Amos Dolbear and published in 1897 in an article called “The Cricket as a Thermometer”.

The formula for temperature Tf in degrees Fahrenheit from the number of chirps per minute N60:

A simplified version only requires counting the number of chirps produced in 15 seconds

Tf=40 + chirps per 15 seconds

The formula for temperature Tc in degrees Celsius is:

A simplified version only requires to count the number
of chirps in 8 seconds and add 5

Tc=5+chirps per 8 seconds

Crickets as Pests

The mole cricket lives almost exclusively in underground digging tunnels. Their main tunnels are used for feeding and for escape. It causes great damage by continuous burrowing and damaging the roots of agricultural crops. As they tunnel through the top few centimeters of soil they push the ground up in little ridges, increasing evaporation of surface moisture, disturbing germinating seeds and damaging the delicate young roots of seedlings. The adults (2-3 cm in length) feed on roots, tubers, underground stems, and ground fruits. In their native lands, mole crickets have natural enemies that keep them under control. This is not the case when they have been accidentally introduced to other parts of the world.

Removing Crickets from Your House

Harborage Removal

Reduce clutter, piles, etc. to reduce potential harborage and hiding areas.

Seal all potential entry points, such as cracks in the foundation, and gaps around doors and low windows.

Place glue traps in the areas of the room where chirping is heard, and along with areas like walls, windows or doorways.

Diatomaceous Earth
Apply Diatomaceous Earth both indoors and outdoors. This is a natural abrasive, white powder that wears through the cricket’s outer shell causing it to dehydrate and die.

Spray pesticides along with windows, corners and basement areas.

Outdoor Lighting
Crickets are attracted to lights. Replace the outdoors lights with low-pressure sodium vapor lamps or yellow incandescent bug lights.

Allow Natural Enemies to Thrive
Plenty of active enemies such as lizards, birds also help to keep
the cricket population in check.

Crickets as Pets

Crickets are kept as pets in many parts of the world; their cages are often very beautiful. Some crickets are chosen for the musical tone of their chirpings. One kind, in Asia, is known as Kin Chung, or golden bell. Others are kept for their fighting ability. In many places, a cricket in the house is thought to bring good fortune.

Cricket House

An empty fish tank or a tall, clear glass jar with an inch or so of soil and a few dry leaves in the bottom makes a satisfactory cage. Put a cover on it made of perforated cellophane or fine-mesh wire netting.

A male and a female get along well in a cage, but two males may fight to the death, and one female has been known to kill another. Several field and ground crickets will live together happily in a large cage, each chirping his own song.


You can feed your cricket fresh fruit, vegetables, seeds, and grains. If crickets are not kept well fed they will prey on one another. Most insects need to drink, so put a lid filled with water into each container. Be sure to change the water every day.

Cricket Breeding – Life Cycle of Crickets

Crickets as Food

Entomophagy is the practice of eating insects. Worldwide, insects are part of the traditional diets of at least 2 billion people in around 100 countries. By the year 2050, the world‘s population will have reached 9 billion people. There has been promising research on the nutrition, safety, and sustainability of crickets as food.

Meat production uses a huge amount of space, animal feed, and energy, and insects, are less demanding of these resources. Insects produce 100 times less greenhouse gas, require six times less feed than beef.
Crickets are an incredible source of protein: 100 grams of crickets has 21 grams of protein, compared to beef’s 26 grams.

There are many species of cricket consumed worldwide, such as the field cricket(Gryllus genus), and the house cricket (Acheta genus). The most common insect integrated into food is the Cricket, usually dried and milled into a powder usually called cricket flour. It is because of the high protein content of crickets that they can be used to make protein bars, cricket flour can replace the wheat flour so commonly used in food products.
