Jerusalem crickets are fascinating insects known for their bizarre appearance and large size. They belong to the Stenopelmatidae family and can be found in North America. Among the largest crickets in the continent, Jerusalem crickets are a sight to behold for enthusiasts and casual observers alike.
These crickets’ body length ranges from 1.5 to 3 inches, making them quite prominent in the insect world. Sporting a human-like head with large mandibles, these wingless creatures exhibit an amber coloration with dark stripes on their abdomen, giving them a striking appearance that’s hard to miss.
Native to regions such as the western United States and Mexico, Jerusalem crickets are nocturnal and spend their time predominantly underground. Though they do not possess the ability to chirp like other cricket species, they still manage to communicate through drumming on the ground, adding to the repertoire of unique characteristics that set them apart.
Understanding Jerusalem Crickets
Jerusalem crickets (Stenopelmatus species) are one of the largest cricket species in North America, measuring around 1.5 to 2 inches in length1. They have:
- A large, round head
- A segmented, striped abdomen
- Spindly, long legs
- Strong jaws for chewing
Species and Distribution
There are multiple species of Jerusalem crickets, including:
- Stenopelmatus with 33 named entities
- Ammopelmatus with 2 described species
- Viscainopelmatus with 1 described species
- Stenopelmatopterus with 3 described species2
Jerusalem crickets can be found throughout the western United States, from Canada to Mexico, and as far east as Montana, Wyoming, Colorado, New Mexico, and parts of Texas and Oklahoma3.
Here’s a comparison of Jerusalem crickets and the closely related Mormon crickets:
|Feature||Jerusalem Cricket||Mormon Cricket|
|Size||1.5 to 2 inches in length1||Slightly larger than Jerusalem crickets4|
|Diet||Insects, plant roots, tubers, decaying plant and animal material3||Forbs, grasses, shrubs, and cultivated forage crops4|
|Native Region||Western United States (Canada to Mexico)||Also native to the western United States4|
|Pest Status||Generally not considered pests||Can be pests due to soil erosion and poor water quality4|
|Related Insects||Grasshoppers, crickets, and katydids1||Similar insect group as Jerusalem crickets4|
Habitat and Behavior
Burrowing and Nocturnal Habits
Jerusalem crickets, also known as niño de la tierra or stone crickets, are unique insects found in the western United States. They mostly live underground, creating burrows in sandy soils and can be found hiding beneath rocks, logs, and other debris1. These crickets are mostly nocturnal, venturing out at night in search of food, such as plant roots, and to mate2.
- Color: brownish or reddish in color
- Size: large, 1.5 to 2 inches in length
- Environment: sandy soils, beneath rocks, logs, and other debris
An interesting trait of these insects is their ability to burrow, creating tunnels underground that provide them protection from their environment1. Their strong hind legs are adapted for digging while their body shape helps them move easily through the soil1.
Communication and Mating
Jerusalem crickets use a range of communication methods, including chirping, hissing, and creating drumming sounds by banging their abdomens against the ground3. This drumming sound, along with their wingless and nocturnal nature, makes them somewhat different from other cricket species3.
- Communication: chirping, hissing, drumming sounds
- Reproduction: mating occurs on the surface at night
In the springtime, Jerusalem crickets come out during the day to find mates2. After mating, females lay their eggs underground in moist soil, often near the roots of plants1. Their reproduction rates are relatively low, and they can take 2 to 5 years to reach adulthood3.
|Characteristic||Jerusalem Cricket||Common Cricket|
|Communication||Chirping, hissing, drumming3||Chirping|
|Mating Location||Surface at night2|
Diet and Predators
Jerusalem crickets, also known as the “potato bug,” are commonly found in the western United States and Mexico. They are known for their strong mandibles and large size, which can be up to 3 inches in length.
These insects mostly feed on organic matter, including the roots and tubers of plants. They can sometimes cause damage to gardens by munching on root systems.
For example, Jerusalem crickets can feed on:
- Decaying plant material
- Roots of various plants
- Tubers, such as potatoes
Jerusalem crickets have several predators, ranging from animals to insects like wasps. Some animals that can prey on these cricket-like insects include bats, birds, and lizards.
A comparison of some natural enemies of the Jerusalem cricket is as follows:
|Predator||Type of animal or insect||Common Locations|
Jerusalem crickets may hiss when threatened; however, this hissing sound is caused by their winglessness and not as a defense mechanism.
Interaction with Humans
Pest and Crop Control
Jerusalem crickets, also known as potato bugs or cara de niño, are nocturnal insects that mainly stay in the ground and don’t usually cause harm to crops or plants. They feed on other insects, decaying plants, and roots, which makes them beneficial for pest and crop control.
However, in some cases, they can be considered pests when their numbers increase and they damage gardens or crops by feeding on roots. Some agricultural methods employed include encouraging natural predators like birds and reptiles, or using habitat management techniques to reduce their population.
Bite and Venom Misconceptions
Contrary to some myths, Jerusalem crickets do not possess venom or a stinging apparatus. Though known for their painful bite, the pain results from their strong mandibles, which can draw blood when threatened. Here is a list of their features related to their interaction with humans:
- Strong mandibles
- No venom
- No sting
- Painful, but not dangerous
For a better understanding, here is a table comparing Jerusalem crickets to common venomous creatures:
|Ant||Yes||Yes||Yes||No (except for some species)|
Overall, Jerusalem crickets are harmless creatures that play a significant role in pest and crop control. They do not pose any extreme threat to human beings or cause any severe damage, as their bites are painful but not venomous. Proper handling and understanding of these insects can ensure a peaceful coexistence between them and humans.
Spanish and Native American Names
Jerusalem crickets are also known by various names in different cultures. In Spanish, they are called niña de la tierra, which translates to child of the earth, reflecting the insect’s burrowing habits. Native American cultures have their own names for this insect, such as chaco, which comes from the Hopi people.
Features of Jerusalem crickets:
- Large, human-like head
- Strong jaws for chewing
- Amber-colored body
- Dark stripes on abdomen
- Long, massive legs for burrowing
Portrayal in Literature and Media
Jerusalem crickets have been portrayed in various forms of literature and media, often as creatures of intrigue or subjects of folklore. Examples include stories about encounters with these insects and their possible cultural or spiritual significance. With their unique appearance, Jerusalem crickets can inspire creativity and imagination.
Comparing Jerusalem cricket to Colorado potato beetle:
|Feature||Jerusalem cricket||Colorado potato beetle|
|Appearance||Large, human-like head;||Small, oval-shaped body;|
|amber-colored body with||yellow-orange with black|
|dark stripes on abdomen||stripes on wing covers;|
|Size||1.5 to 2 inches||1/3 inch|
|Distribution||Western United States||United States, Europe|
|Habitat||Soil, under rocks||Potato fields|
In conclusion, the cultural significance of Jerusalem crickets can be seen through their various names in different languages and their portrayals in literature and media. While they might seem intimidating or bizarre, these insects play an integral part in our natural world and continue to fascinate people across cultures.

Letter 1 – Potato Bug
Looks like a bumblebee crossed with a lobster
Wed, Nov 26, 2008 at 9:02 PM
My husband found this bug outside our sliding glass door tonight. We live in the San Francisco Bay Area. We get a lot of wildlife in our yard, and I’ve seen quite a few interesting bugs, including black widows, wolf spiders, and lots of bees. In fact, at first I thought that this bug was a bumblebee, but then I noticed the head, which looks completely different. The bug is about 3 inches long and appears not to have any wings. I couldn’t find any pictures online to identify it. Any idea what it is? Thanks!

Potato Bugs or Jerusalem Crickets like the one in your photo are one of our most frequently requested identifications, so much so that we only post a fraction of the letters we receive. We get so many requests that along with House Centipedes, Potato Bugs are at the top of the Top Ten list. We really like your description, and your photo is quite good, so we thought it was time to have a new photo of a Potato Bug on our Homepage, especially since they are frequently seen after rains in the Western part of the country.

Dear bugman, thank you for helping us out. My 2 1/2 year old son found this bug when we were clearing a space to set up a vegetable garden in my back yard. It burrows in the dirt. Is at least an inch long. It is spring in San Diego. Any help would be appreciated – my 2 sons are very curious, and so am I!
Signature: Thank you for your help, a curious mom
Dear curious mom,
You have encountered a real Southern California icon, the Potato Bug or Jerusalem Cricket, a subterranean relative of crickets and grasshoppers from the order Orthoptera. Potato Bugs are generally encountered during the winter months, often after the rains.
Thank you. Do you mean potato bug as in grey rolly polly?
We have never heard of a Roly Poly being called a Potato Bug, but that is the problem with using common names. Roly Poly is another common name for Pillbugs or Wood Lice in the family Armadillidiidae while Potato Bugs are Orthopterans in the genus Stenopelmatus.

what is this bug?
Recently, my family and I went for a walk and saw this creepy crawly cross our path (see attachment). It was approx. the size of a mouse and moved at about the same speed. I have tried to figure out what it could be but can’t seem to make any progress. It appears to be a very large type of ant but it’s hind legs look like a spider’s. Also, it was about 3" long. Please advise. Please accept my apologies for the quality of the photo as I took it with my cell phone. I sharpened the image a bit in photoshop. Thank you,
Our homepage is never without a photo of a Potato Bug or Jerusalem Cricket, so we can’t understand how you missed it.

What’s THIS bug???
Last night, late I stepped out to let the dog out and saw a big critter on the patio. I got out my flashlight and saw this enormous bug. I scooped him into a glass to take a few pics. He was nearly two inches long! I returned him to the wild, out of my curious dog’s reach. I don’t think I’ve ever seen anything like this. I live in Southern California. Is he dangerous? He sort of looks that way. He has three stinger type things on his tail. Looking forward to learn more, if you can help!
We are thrilled that you wrote back that you identified your Potato Bug or Jerusalem Cricket from our site. The photo is truly gorgeous.
Letter 6 – Potato Bug
On 7/11/2006, you posted a picture of the potato bug, a.k.a., the Jerusalem Cricket (which isn’t really a cricket, and isn’t really from Jerusalem, unless there’s a Jerusalem, California.) I wanted to provide you with a few clear pictures for your site. I have more if you like. These were found in my boss’ office in Simi Valley, CA.
Thanks for your submission. We always try to keep an image of a Potato Bug on our homepage. Technically, in the list of things they are not, they are not Bugs either. Jerusalem Crickets are in the family Stenopelmatidae in the order Orthoptera. Orthoptera does include crickets, grasshoppers and katydids.
Letter 7 – Potato Bug
Hello. I keep finding this wierd bug in my garage. I live in San Diego. The garage has books, tools, random things, and some dog food in a plastic, sealed container. I attached a picture. In case the picture doesn’t come out. It is about an inch and a half long, shiny, with six legs and tan and brown stripes on the back. Any help would be great because it kind of is giving me the heebie jeebies. I have found 3 or 4 of them. Thank you!!!!
The Potato Bug or Jerusalem Cricket or Nino de la Tierra is one of our most common identification requests from the American Southwest. It is perfectly harmless, and is generally found underground. The rainy season drives them above ground when they are most commonly encountered.

My friend found this 4" bug in California. He says: "Here’s the bug. Found at Switzer Falls in the Angeles National Forest, San Gabriel Mountains. I’m sure there will be a website somewhere that can tell you which nightmare insects live in the ANF. This thing is about four inches long. No joke. Sketchy. Any ideas?
There is a website with information about just about everything, though some of them have misinformation. This is a Potato Bug or Jerusalem Cricket, the subject of numerous queries to our site.

Reports of Potato Bugs or Jerusalem Crickets from the American Northwest are not as common as they are in the Southwest, so we presume the insects themselves are not quite as wellknown there. Thanks for sending in your photograph.

This thing is NASTY!
Please help me Identify this thing! I found it inside my house on the floor. Im thinking that it might have come in with a bunch of fireworks I had recently purchased! I appreciate your time and your help! Thanks!

We are compelled to come to the defense of your Potato Bug or Jerusalem Cricket, and inform readers that they are not nasty. They are shy nocturnal underground dwellers that often appear inside homes and garages after a rain. They are normally one of our most common identification requests from the Western states, especially California. Our last posting was in January and we suspect the record low rainfall in California last year is responsible for low sightings recently. Potato Bugs are also known as Ninos de la Tierra or Children of the Earth in Spanish and they are in the family Stenopelmatidae. Potato Bugs do have strong mandibles and will bite, but they are not poisonous and in most cases will not even break the skin.
Letter 12 – Potato Bug
We wanted to add our Potato Bug to your file. We found this one in Brea, California. As you can see he his quite big. He is making a noise, like a hissing sound. Is this my imagination?
Certain insects are able to make a hissing sound by rubbing portions of their body together, a method known as stridulation.
Letter 13 – Potato Bug
I live in Carlsbad, California and have been trying to figure out what type of insect this is. I found one in my kitchen a couple months ago and saw another one tonight on my doorstep – I’ve only seen it at night. It looks like a giant ant (about the length of my thumb) with some roach characteristics. Any idea what it is? I’ve attached a picture. If you could solve this mystery for me I would REALLY appreciate it. Thanks so much!!
We are posting your image and letter along with the other recent Potato Bug photos in our featured Bug of the Month for January section.

Please tell me what It is.
I hope you could tell me what this is too. I found this in Los Angeles, California near DownTown Los Angeles on December 14, 2006. It didn’t move even if I threw a quarter or a penny. It’s more than 2"x1"x1". I believe it doesn’t have any wings and the shape might look like a bee w/o wings, or a giant ant. Hope to hear from you soon. Best Regards,
This is probably our most common insect query subject from southern California. This is a Potato Bug or Jerusalem Cricket. They are subterranean dwellers that are often discovered in gardens, especially in the winter and spring during rainy season.

My boyfriend stumbled upon this palm-sized insect (2.5 or 3 inches?) today at our house in Los Angeles, CA. He was crawling around in circles and scared my boyfriend half to death. The pictures should be self explanatory. We’d like to know as much as possible about this creature. If our dog sniffed it would she get stung or pinched? It looks diabolical.

This is the second time we found this bug in our yard. Last year the one we saw was more opague/and albino like than this one. We live in the hills of Los Angelels. Our zip code is 90065. We think that whatever it is it must be the queen of it’s species, if not, we would hate to see the dominant version. We hope that it is not poisonous (we have kids and dogs) and that it does not travel in large numbers and/or breed often. Any info you could provide would be greatly appreciated.

Dear HJH Goring Family,
The Potato Bug or Jerusalem Cricket is one of our top 10 identification requests, and it may be number 1 in Southern California. This subterranean dweller usually comes to the surface after a heavy rain, so its appearance right now is a tad bit uncharacteristic. The Potato Bug is not poisonous, nor does it travel in packs. It does have strong jaws and it is possible that a bite might draw blood in a thin skinned individual.

September 7, 2009
We saw this out in the desert this past weekend at Five Mile Pass in Utah and would like to know what it is.
This is a Potato Bug or Jerusalem Cricket in the genus Stenopelmatus. There needs to be a thorough study of the genus in order to identify the different species. BugGuide indicates: “Capinera (1) states the genus needs revision, with 14 species currently described in the family, but more than 60 North American species likely–most presumably in this genus.” Potato Bugs have many colorful common names. At one point, we believed Sand Puppy was one of them, but now we believe that the creatures known as Sand Puppies are actually Solpugids.

November 5, 2009
we found this creature in a sink in our house in Pacific Palisades, Los Angeles. It is much bigger than any giant termite described on your website or in wikipedia, but looks similar in shape.
You can see on the picture that its head is only a little smaller than the dime.
When we tried to catch it, it disappeared into the drain, and lived in the water for several days, but kept coming up (for air?).
We tried to tease it out with a pipe cleaner to catch it, but it attacked the pipe cleaner, biting it, and pulling it from our hands.
This is a very strong and energetic bug.
It is sensitive to light and sound. When we caught it, it was a pale beige in color, probably from being under water. But within 30 minutes or so, it regained its black-and-brown-stripe pattern.
We would love to know what this is. And also, what it eats, as my kids would like to keep for a few days.
Los Angeles, CA
Dear Curious Angeleno,
We have received so many identification requests for Potato Bugs or Jerusalem Crickets in the past few day that we decided to post the one with the best letter and photo, and that is your query. Originally we just wrote back to you that this was a Potato Bug and didn’t provide more. This typically subterranean insect is found in the Western United States, typically in arid regions. There is much information available online and it is one of our Top 10 identification requests. Good luck with keeping it as a pet for a few days, and we hope you will release it afterward. Try feeding it root vegetables like carrots and potatoes. Despite its common name, it is not really a pest that consumes potatoes. Though they are harmless, Potato Bugs do have strong jaws and will bite if provoked. Again, other than a nip, the Potato Bug is harmless.

Unsual bug in the garden
December 11, 2009
I was tying back some plants in preparation for rain…soon after that I saw a large bug (quarter sized) that looks like a mutation of a grasshopper, an ant, and a bee. Not sure what this could be…Is it a beneficiary garden bug or a pest? Thanks!
This has to be one of our favorite images of a Potato Bug or Jerusalem Cricket ever. The Navajo name for this amazing creature translates to Skull Insect and the Spanish name translates to Child of the Earth, both of which refer to the almost human characteristics. Your photo reminds us a bit of a naughty puppy trying to dig its way under the fence. Potato Bugs are subterranean dwellers that feed on roots and they are generally sighted in the winter. Rains often force them to the surface. We don’t consider them to be harmful, but they do have powerful jaws and they will not hesitate to give a painful pinch if carelessly handled.

I was walking along when I saw this thing, it looks like a giant ant, it was well over 1.5 inches. I was wondering what it was, and my friend said it could be _____ (spanish name) and that it’s poisonous and if you see its tummy, it looks like a baby’s face. Is this true?
We just posted a letter yesterday of a Potato Bug sighting. These are legendary insects in Southern California and they are also found in numerous other locations in western North America. The recent unseasonal rains is causing them to emerge from their normally subterranean burrows, making them more visible. There are many superstitions regarding the Potato Bug, which is also known as the Jerusalem Cricket. In Spanish it is called Niña de la Tierra or Child of the Earth and it is not poisonous, though it does have strong jaws and could theoretically produce a painful bite. They are not dangerous.

Thank you for submitting your identification request.
Please understand that we have a very small staff that does this as a labor of love. We cannot answer all submissions (not by a long shot). But we’ll do the best we can!
We recently moved to Cedar Mesa on Colorado’s Western Slope. It’s mid-October, so the days start out cool, warm up for a bit, and the night time temps are about in the upper 30’s to 40’s.
At the beginning of our late-morning stoll on the property, I found what appears to be a mixed-breed insect heading towards a cedar tree from under the back deck.
It’s about 1.5″ – 2″ long, and has a head like a very giant ant or grasshopper, its 6 legs are similar to bean sprouts but look like beetle legs, and its abdomen looks like that of a wasp. It does not appear to have been injured or mutilated (missing wings, etc.).
Would you happen to have seen one of these before or know what it is?

HUGE Bug under my children’s Blanket
Location: Under a blanket, In a House in Northern California
November 15, 2010 12:56 am
HUGE does not begin to describe it, this bug is COLOSSAL, ENORMOUS, MAMMOTH, etc. I was making up a floor-bed for my children, and when I flipped back a blanket, I saw this beige underside of a bug. By the sheer size and uniform coloration I was sure it was one of my boys’ rubber bugs (they have quite a few). I called one over to come pick it up, thinking I’d ”psyche” him out and tickle the back of his neck as he picked it up. Teehee! Well, he said, ”NO!” when I told him to pick it up. THANK GOODNESS HE DID! I bent down to grab it myself, when thought, what detail, how amazing, in rubber? It was 2 inches long almost. Is that… mandibles or something??? THEN… IT TWITCHED and I nearly violated my drawers.
IT WAS A REAL BUG !!! I ran and got a glass jar and a heavy piece of paper, and me and my 2 and 4 year old boys captured the bug. We lidded him up and kept him overnight (sorry bug, I didn’t know what he would eat so he was probably very hungry) so we could photo him and release him in the morning.
When he was dumped out on the ground we got a good last look at him. He sort of burrowed happily into the loose dirt, it looked like he was comfortable in the dirt and not so much a tree-bug. I wanted to touch him, so very gently extended my index finger to stroke the back of him. What happened next is a blur, he sort of gripped onto me, I suppose with his back legs? I yelped and reflexively flung him over my shoulder, felt bad, so looked around till I spotted him on the grass, and scooted out of the way yelling GOOD BYE BUG!! OOH HE TOUCHED ME!
And the boys thought it was very funny, and asked if he would go eat now (I hope).
Anyways, he was about 2 inches long, had a striped body, a very noble face and reminded me of a gigantic ant. I thought maybe he was a cricket? A locust? I have no idea! I have never in my life seen a bug this huge.
The boys were quite fond of him and asked to keep him as Pet. But I told them we don’t know what it is for him to eat so we should let him go.
Your detailed account of an encounter with a Potato Bug is highly entertaining. Your observations that it resembled a cricket is astute. Potato Bugs and Crickets are in the same insect order and another common name is Jerusalem Cricket. Potato Bugs do have strong mandibles, and though they are not dangerous, they may deliver a painful bite if carelessly handled, possibly even drawing blood.
Wow! Thank you so much for your response. Potato Bug. I’m very glad it did not bite me! And even more glad I found him before my children crawled into bed with him. What an interesting creature. I believe I will learn a bit more about them, and write this out for my son’s schoolwork. Thanks again!

What in the world is this?
Location: Rancho Palos Verdes, southern California
February 20, 2011 6:39 pm
One morning my son wandered into our garage and uttered this blood-curdling screech. There on the floor was this guy. It was about 2 inches long (maybe even a big bigger) and resembled a giant wingless bee.
Being an intrepid scientist, as my 12 year old ran screaming back into the house, I dashed out to the garage with a bowl to trap the critter. I brought him/her into the house so we could all look at this baby a bit closer.
I’m hoping it’s not something that will munch on my house because I let it go in the field behind the house.
The picture is a bit blurry because my buggy friend is in a bowl with a very thick piece of glass on top. Any thoughts?
I found the answer!

Well I looked back through your blog and found the answer to the question I had asked earlier. The little critter that was visiting my garage was a Jerusalem cricket.
Thanks for the great blog and the answer to my question.
We are pleased that our archive provided you with your answer. Potato Bug sightings are most common in the winter after rains.
