Crickets are fascinating insects, known for their distinctive chirping sounds and jumping abilities. Their physical features play a significant role in their behavior, and one such feature is their legs.
These insects possess six legs, as they are part of the insect family. Their legs have specific functions that enable them to thrive in their environment. For example, crickets have large back legs, which are designed for jumping and hopping source. This adaptation allows them to evade predators and move swiftly through their surroundings.
In addition to their six legs, crickets have other notable features like long antennae and, in some cases, wings. While there are some variations in color and size among cricket species, their basic anatomical structure remains consistent source. By understanding their physical attributes and adaptations, we can better appreciate the role crickets play in their ecosystems.
Basic Features of Crickets
Crickets are insects with a flattened body, a rounded head, and long, thin antennae. They typically have a brown, black, or green coloration. Male crickets produce chirping sounds by rubbing their wings together.
Number of Legs
Crickets, like all insects, have six legs. These include:
- Two front legs
- Two middle legs
- Two hind legs
Comparison with Grasshoppers
Crickets and grasshoppers may appear similar, but they have distinct differences:
|Longer than body length
|Large and used for jumping
|Long and strong for leaping
|Rubbing wings together
|Rubbing legs against wings
Crickets have compound eyes, which consist of many smaller optic units. Their eyes are well-suited for detecting movement and seeing in low light conditions.
One of the most obvious features of crickets is their long antennae, which can be as long as their body or even longer. Cricket antennae are used for:
- Sensing their environment
- Detecting food
- Finding mates
Crickets have large hind legs that are excellent for jumping or hopping. These powerful legs allow crickets to quickly escape predators or move across their environment.
Behavior and Habitat
Crickets are nocturnal insects, meaning they are primarily active during the night. They move around to search for food and mates under the cover of darkness.
Chirping and Singing
Male crickets are known for their distinctive chirping sounds. They produce these sounds by rubbing their wings together to attract females for mating. With each species having a unique pattern of chirping, it helps females identify their specific mates.
Temperature Influence on Chirps
The rate of cricket chirps is influenced by temperature. Crickets tend to chirp more frequently when it’s warm, and their chirping slows down in colder temperatures. An interesting fact is that the relationship between temperature and chirping rate can be used to estimate the temperature in degrees Fahrenheit:
Temperature (°F) = (Number of chirps in 15 seconds + 37)
Habitats and Range
Crickets can be found in various habitats, such as:
- Fields and meadows
- Urban and suburban areas
Their range varies depending on the species, but they are typically found in temperate and tropical environments.
Comparison between two common cricket species:
|Urban and suburban areas
|Black or brown
|Fields, meadows, and forests
In summary, crickets are nocturnal insects with unique behaviors. Their distinctive chirping sounds are produced by male crickets for mating purposes, and temperature influences the rate of their chirps. They can be found in a variety of habitats, adapting to different environments, depending on their specific species.
Reproduction and Life Cycle
Mating and Courtship
Crickets engage in a fascinating mating ritual. Male crickets attract females by chirping, which they produce by rubbing their wings together. The female cricket selects a suitable mate based on the male’s song, showcasing specific preferences in chirp patterns.
Female Cricket Ovipositor
The ovipositor is a vital aspect of female crickets’ reproductive anatomy, functioning as an egg-laying device that extends from the abdomen. This sword-like structure assists in depositing eggs into appropriate substrates, ensuring their survival.
Eggs and Nymphs
Upon mating, female crickets lay their eggs in moist soils or other suitable materials. A single female can lay hundreds of eggs, depending on the species. The eggs subsequently hatch into nymphs, which resemble smaller versions of adult crickets, lacking wings.
Lifespan and Development
Crickets’ development proceeds through several molts before reaching adulthood, which is marked by the growth of wings. Overall, crickets generally have a one-generation-per-year lifecycle in certain geographic locations like Minnesota. Their adult lifespan varies by species but is typically around 2-3 months.
Characteristics of crickets during reproduction:
- Male crickets produce chirps to attract females
- Females have an ovipositor for egg-laying
- Eggs hatch into nymphs, eventually developing into adult crickets
Cricket Development Stages Comparison Table:
|Deposited in moist soils or substrates
|Weeks to months
|Resemble adults without wings
|Wings present, capable of reproduction
Cultural and Human Significance
Symbolism and Good Luck
Crickets have long been associated with good luck and fortune in many cultures. In Chinese culture, for example, crickets are seen as symbols of prosperity and happiness, often kept as pets in small cages to enjoy their melodious chirping.
- Sign of good luck in various cultures
- Kept as pets in some Asian countries for their songs
Edible Crickets and Nutrition
Crickets are gaining popularity as a sustainable, protein-rich food source. They offer a high-protein alternative to traditional livestock with lower environmental impact and resource requirements. Some companies are even producing cricket-based snacks and nutrition bars, making consuming cricket-infused products more accessible.
- High in protein and nutrients
- Environmentally sustainable compared to traditional livestock
Cricket fighting has been a popular pastime in China and other countries for centuries, with participants carefully selecting and training crickets for battles. These events often take place during festivals, bringing fans together to appreciate the athleticism and fighting prowess of their prized insects.
- Long history as a pastime
- Practiced mainly in China and parts of Asia
Crickets in Literature and History
Crickets have played a significant role in world history, particularly in literature, visual arts, and music. They often symbolize change or serve as a reminder of the beauty of nature. Examples include the cricket in Charles Dickens’s “A Christmas Carol” and the famous Chinese story of the “Cricket Boy”, a tale of wisdom and determination.
- Representations in literature and visual arts
- Symbolize change or appreciation for nature
Classification and Species Varieties
Crickets belong to the Orthoptera order, which also includes grasshoppers and katydids. Members of this order have:
- Large back legs for jumping
- Leathery front wings (tegmina) to protect delicate back wings
- Long antennae, often as long as their body length
The Gryllidae family consists of true crickets that have the following characteristics:
- Rounded heads
- Thin, long antennae
- Wings bent down on the sides of their body
- Flattened body appearance
- Mostly brown in color, with some black and green varieties
Grylloidea is a superfamily that includes the Gryllidae family and other cricket-like insects. They typically share the basic cricket features listed in the Gryllidae family section above.
Common Cricket Types

Predators and Interaction with Other Animals
Crickets are a vital food source for many animals, including:
For example, frogs and lizards often hunt crickets for their protein and energy content.
Crickets can also fall prey to parasitic flies. These flies lay eggs on or near crickets, and their larvae feed on the cricket’s insides, eventually killing the host.
Crickets as Pets
Crickets can be popular pets or part of a pet’s diet. For example, some people keep cricket colonies for feeding reptiles like bearded dragons, while others keep crickets as pets for their unique chirping sounds.

Letter 1 – Crickets in Greece fall victim to bug sprays and stomping
Please help me identify this bug
Location: Trilofos, Thessaloniki, Central Macedonia, Greece
October 8, 2010 4:21 am
I recently moved to a country house in Northern Greece. Since the first few days the house had this visitor, along with his brothers, cousins and other relatives.
They are black, they jump but not very well, their usual movement is a walk with plenty of stops. They exist in large numbers around the house and they like coming in through any hole, or under the doors.
They are strong but not very fast. They like holes, corners and other hideouts. They die with cockroach sprays but not fast. If you step on them they make a crunchy noise and sometimes they don’t die, they need a second harder hit.
I am familiar, at least visually with most of the big bugs of the region, but this one is a new one for me.
I looks and moves like a bizarre hybrid between a cockroach and a grasshopper.
As I have a newborn baby girl, that will start crawling soon, I would like the species identified, in case it can be harmful in any way to the baby. I appreciate all your help.
We hope we are able to convince you that you do not need to poison or stomp on these interesting Field Crickets any longer. We believe your Field Cricket is in the genus Gryllus, and though they might do some damage in the garden, they are benign insects that are actually kept as pets in Japan because of their melodic chirping. You can read more about Crickets in captivity on Insects.org and perhaps you will learn to appreciate the wonder of the insect world that surrounds you.
Thank you very much for your prompt response. I am convinced…. but
now I will need to convince my wife too, a much harder job I am afraid
when it comes to these critters.
I have to say though that our crickets do not chirp – melodically or
otherwise. Maybe they see no reason to chirp given that the summer is
If any Japanese people want a new pet, I have a few hundred
immediately available and they are welcome to come and collect them
Thank you again,
Letter 2 – Fitchia Assassin Nymphs feeding on Cricket
This is a picture of what I believe to be two immature assassin bugs, the bottom one eating a cricket. They were found in my yard in Lynn Haven, FL. Please help me identify their species.
We don’t want to even attempt a species identification on a nymph, but we are fairly certain the genus is Zelus.
Update: May 4, 2013
We just received a comment correcting the genus as being Fitchia. BugGuide images verify that identification.
Letter 3 – Crickets in Mount Washington
Subject: Crickets in Mount Washington
Location: Mount Washington, Los Angeles, California
August 22, 2013
A couple of quick questions.
Growing up on Mt. Washington, I was often lulled to sleep in the summer months by the hundreds of crickets in the open lot above our home. When I purchased the family home in the early 90’s, not only were the crickets absent, so were butterflies, bees, birds and damn near everything after the malathion spraying.
I occasionally hear some crickets in the evening, but not often. I’d like to repopulate, but before I take any type of action, thought I would check in. I can’t seem to find any real information on whether crickets are invasive, pest like, damaging to flora or any other real info. I see that Mole crickets are a pest.
What are your thoughts?
Also saw an interesting insect this evening hovering around an outside light. Very lacy, silver gray in color, perhaps 1 1/2 inches long, with a build very, very similar to a dragonfly. Didn’t have a camera handy, but I will keep an eye open for it again.
The two “singing” insects we find in our Mount Washington garden with frequency are Tree Crickets and Katydids. We would not release pet store crickets in your yard. We were going to provide you with links to What’s That Bug?, but it appears there is technical difficulty right now.
Update: August 25, 2013
Well, we managed to create a post and provide some links. We will check with Julian Donahue regarding other Crickets or musical insects in Mount Washington.
Julian Donahue responds
While Kathy and I enjoy hearing the tree crickets on warm evenings, I haven’t spent any time figuring out the other crickets I occasionally see–sometimes I see some that look like field crickets, but are more slender. And sometimes I find camel crickets drowned in the pool, but these are incapable of producing any sound.
Update: September 29, 2013
Thanks for the note. I alway appreciate your replies. And am very glad to have such a knowledgeable Mt. Washington neighbor.
In all my years living in Mt. Washington 1963 til 1983 and 1992 to present, I don’t ever recall seeing a Tree Cricket. I’ll keep my eyes open in the future. In regard to the Bush Katydid, unless they turn brown and have short antennae, I’ve never seen any of those over here on Crane either.
However I have seen common house crickets and I am telling you prior to the Malathion disaster (may those public servants roast in hell) the entire 5 lots behind us sang every night with house crickets.
Do you think there might be various pockets around the hill.
Honestly, when I was a kid the hill behind us sang every night in the summer. On and off since we moved back, but not like in the 1960’s – 1970’s.
What’s your take?
Charles Hogue lists both the native black Field Cricket, Gryllus species, and the brown European House Cricket, Acheta domesticus, as living in the Los Angeles area. We haven’t really noticed either in Mount Washington, however the European House Cricket is the species sold in pet stores. Were your childhood crickets black Field Crickets or Brown House Crickets? As an aside, while living in Glassell Park in the early 1980s, we did have a Field Cricket take up residence in the drain of the bathroom sink. It would “sing” whenever the water was turned on. We were careful not to run the water too hot or too hard so that the cricket wouldn’t get scalded or washed away. It lived in the bathroom for several weeks. If there were Field Crickets in Glassell Park, we cannot imagine them not being found in adjacent Mount Washington.
Letter 4 – Field Cricket
Subject: Ia it a “Biter”?
Location: Union, MO, USA
July 20, 2017 11:51 am
Found this guy in my basement. He was just crawling around although it appears he might have wings. Below is a picture of the insect and a picture of my bites. As you can see there are smaller bites around the large ones although those dark spots are only old bites and not any recent ones. Could you please tell me if this is a match?
Signature: -Itchy Itchy Ichabod
Dear Itchy Itchy Ichabod,
We had to respond to your just because of your signature. This is a female Field Cricket in the genus Gryllus and she is missing her rear jumping legs. Fleas often bite people on the ankles, and our best guess for your bites is Flea Bites and not this Cricket.
Letter 5 – Gnashing Cricket from South Africa
Subject: South African cricket like bug
Geographic location of the bug: Stuttreheim, Eastern Cape, South Africa
Time: 12:30 AM EDT
Your letter to the bugman: Hi, I found this bug cornered by my cats, and by my Jack Russell Terrier when I took the photos
How you want your letter signed: Dean Sheard
This is one of the Orthopterans (the insect order that includes Crickets) in the family Anostostomatidae, a group that includes Wetas, Parktown Prawns and King Crickets, all common names that we find somewhat confusing when we get identification requests. We located some images on iSpot that are identified as Gnashing Crickets in the genus Henicus that look very similar to your insect, and we verified that identification on Minden Pictures where there is a nearly identical image posted by Katydid expert Piotr Naskrecki, whose authority we trust more than most images posted online.
Letter 6 – Great Grig: Hump-Winged Cricket
Subject: Large cricket?
Geographic location of the bug: McCall, Idaho
Time: 10:17 AM EDT
Your letter to the bugman: Hi! We found this guy on a camping trip at Ponderosa State Park. I’ve been trying to find similar images online but am having trouble. He is very friendly and seems to be flightless.
How you want your letter signed: Ashley & my son Ben, Friend of all Bugs
Dear Ashley & Ben,
Your Hump-Winged Cricket or Great Grig, Cyphoderris monstrosa, which we identified on BugGuide is actually more closely related to Katydids and it is not a true Cricket. The BugGuide description is: “male dark gray dorsally, pale whitish ventrally, with short wings humped up and wrinkled like a loosely-folded blanked heaped on the insect’s back; male subgenital plate with a ventrally-directed process shaped like the nail-pulling claw of a hammer. female either lacks wings or has them reduced to small stubs.” Your individual is a male.
Letter 7 – Dune Cricket from Nepal
Subject: biggest insect I’ve ever seen…
Geographic location of the bug: Sun Kosi river, SE Nepal
Time: 12:31 PM EDT
We found this huge insect on a beach on the Sun Kosi river, 7th October. It was about the size of a child’s hand, with very long antennae. After running around our feet for a while it buried itself in the sand.
Any idea what it is? Sorry the pictures aren’t great but it was dark and raining!
How you want your letter signed: Gareth
This is some species of Longhorned Orthopteran in the suborder Ensifera, but we are not certain of its classification beyond that generality. We suspect this is some species of ground Katydid, possibly a Shieldbacked Katydid. We know we have something similar looking in our archives, but we are unable to locate it. We will contact Katydid expert Piotr Naskrecki to see if he can provide a more specific identification.
Piotr Naskrecki Responds
What a beautiful creature. This is Schizodactylus, a member of the ancient family Schizodactylidae, with members in NE Asia and Southern Africa. Its hind wings are always curled like this, which probably helps them move backwards in their underground burrows.
That must be it – the face, the feet, and the curled-up shape at its back all look the same.
Thanks for your help tracking it down!
