What are Crickets?

Crickets are insects from the family Gryllidae, closely related to grasshoppers and katydids. There are almost 2,500 species of cricket, found primarily in the temperate regions of the world. These insects are perhaps most famous for their distinctive chirping noises, which are created by rubbing the front wings together.

Several features can be used to identify a cricket, and to distinguish it from the related grasshopper. Crickets and grasshoppers both have big, muscular rear legs which are used for jumping, but crickets also have long antennae, in contrast with the short antennae of grasshoppers. The front wings of these animals are small and leathery in texture, while the larger rear wings are usually tucked under the front wings flat against the body, except in flight.

Only males in some species of crickets produce chirping. Several different chirps have been identified by biologists, including a calling song to attract females, and an aggressive song to deter other males. The chirps are also unique to the species, although the casual human ear might not be able to detect the difference.

As a general rule, these insects are nocturnal, and they are also omnivorous. This is another major difference between them and grasshoppers, as grasshoppers are herbivorous. Crickets usually mate in the summer, producing eggs in the fall, with the young hatching in the spring. A single female can lay up to 2,000 eggs, ensuring that at least some of her young survive, despite predation.

In some cultures, the cricket is viewed as lucky. In some parts of China, for example, people like to keep crickets in cages, and in some parts of England, when a cricket chirps indoors, it is viewed as a good omen. They are also regarded as a source of food in parts of Africa and Asia, and many people raise them to feed pets such as lizards and fish. For those who don't feel up to raising their own, some exotic pet suppliers carry them.

The name cricket comes from the Old French criquer, which means to click, a reference to the chirps and clicking noises produced by males. Many people associate the sound of crickets with the evening hours, especially quiet evenings without many people around. In some English-speaking regions of the world, when a comment meets with a deafening silence, the commenter may jokingly make an allusion to these insects, referencing the fact that the room has fallen so silent that if crickets were around, they would be audible.

Frequently Asked Questions

What exactly are crickets?

Crickets are small to medium-sized insects belonging to the family Gryllidae, characterized by their long antennae and powerful hind legs adapted for jumping. They are known for their chirping sound, produced by males rubbing their wings together to attract females. Crickets are omnivorous and play a role in the ecosystem as both prey and predator.

How do crickets make their distinctive chirping sound?

The chirping sound of crickets, also known as stridulation, is made by the males of the species. They produce this sound by rubbing a scraper, a sharp edge on one wing, against a series of ridges, called a file, on the other wing. The frequency of the chirps can vary with temperature, often used as a rough thermometer.

Are crickets considered beneficial or pests?

Crickets can be both beneficial and pests, depending on the context. They contribute to the ecosystem by breaking down plant material and serving as food for various animals. However, in large numbers, they can damage crops, textiles, and invade homes, causing them to be considered pests in those scenarios.

What do crickets eat?

Crickets are omnivorous and have a varied diet that includes plants, fungi, and smaller insects. Some cricket species are scavengers and will feed on decaying plant matter and dead animals. Their dietary flexibility helps them thrive in diverse environments, from grasslands to forests and human dwellings.

How long do crickets live?

The lifespan of a cricket varies among species, but most field crickets live for about two to three months. This short life cycle includes the egg, nymph, and adult stages. Indoor species like the house cricket may live slightly longer due to more stable environmental conditions and consistent food supply.

Can crickets be used as a sustainable protein source for humans?

Yes, crickets are considered a sustainable protein source for humans. They require less land, water, and feed compared to traditional livestock and emit fewer greenhouse gases. Crickets are high in protein, vitamins, and minerals, making them a nutritious option. They are already consumed in many cultures and are gaining popularity in the form of cricket flour and snacks.

I found a cricket in the wastebasket of my office and he's in a clear bread box, with some carrot and apple peels, chirping his wings off right now. So pleasant and soothing. Wonderfully masks the sound of my tinnitus.

I live near a pond, so I get to hear the combination of frogs and crickets every day at twilight. The sound will forever remind me of summers during my youth.

In fact, we have so many crickets in our yard at times that it is hard not to step on them. The dogs think it’s a wonderful game to try and catch them. They actually eat the entire cricket once they catch it.

We were babysitting my cousin when he was barely a year old. He was sitting on the porch when a cricket hopped by, and without hesitation, he picked it up and popped it in his mouth! We scooped it out quickly. I wish he had been old enough to talk, because I would have loved to have asked him what it tasted like.

A cricket in the house is almost impossible to find. Just when you think you have nailed down its location, you hear it somewhere else instead.

I had a cricket in my house the night before my new job started. I really needed to get some good rest, but I spent half the night looking for the cricket. They are good ventriloquists.

I ended up just turning on a loud fan to drown out the noise. I wished I had done that hours ago, but it hadn’t occurred to me until I saw that the cricket was winning the game of hide and seek.

@Mykol - Yes - I am always amazed at how much noise one small cricket can make when you are trying to sleep and there is one in your room.

I don't mind them when I hear them outside, but really don't like having them anywhere in the house.

I have a friend who will buy crickets to feed his iguana. There are many people who have reptiles and pets that eat crickets. Some will even raise their own crickets to feed their pets.

I never intend to have a pet that I have to feed crickets to. I will just stick to listening to them chirp outside in the summer.

I always take advantage of sleeping with my windows open whenever the weather permits. One thing I really enjoy is listening to all the outdoor summer sounds, and this includes hearing the crickets chirp.

When I was growing up we always spent out summer nights sleeping on a screened in porch. The sound of the crickets always reminds me of good summer memories.

I know some people are annoyed by this constant sound, but I find it kind of comforting. The only bad thing is when one gets in the house. Listening to the chirp of a live cricket in the same room as you is much different than listening to them when they are outside.
