Jerusalem crickets are interesting creatures belonging to the insect family. While these insects may look like crickets, they actually belong to a group of flightless insects known as Stenopalmatidae.
One common question about Jerusalem crickets is whether they make any noise. It turns out that these creatures are not your typical chirping crickets. In fact, they produce a different type of noise when disturbed, by rubbing their hind legs along the side of their abdomen, creating a hissing sound or a noise similar to rubbing sandpaper together 1. This unique feature sets them apart from other cricket species, offering insight into their intriguing behavior and adaptations.
When it comes to communication, Jerusalem crickets rely more on vibrations than auditory sounds. They produce mating calls by drumming their abdomen against the ground, and these vibrations are detected through the soil 2. This further emphasizes their distinctiveness when compared to other cricket species.
Understanding Jerusalem Crickets
Physical Characteristics
Jerusalem crickets, often referred to as “Child of the Earth” or “Niño de la Tierra,” are large insects with distinct features. Some of their notable physical characteristics include:
- Rounded, yellowish to brownish bodies
- Large, bald, humanoid-like heads
- Powerful, spiny legs for digging
- No wings, thus flightless
These crickets do not produce the typical chirping sounds like other cricket species. However, when disturbed, they can make a hissing noise by rubbing their hind legs along their abdomen, similar to the sound of rubbing sandpaper together.
Habitat and Distribution
Jerusalem crickets are predominantly found in North America, particularly in the western United States, Mexico, and Central America. Their habitat ranges from arid, sandy areas to grasslands and forests, depending on the species. Some key points to note about their habitat and distribution are:
- Found in regions like California, Oklahoma, and Mexico
- Prefer moist soil for burrowing and laying eggs
- Mostly nocturnal, hiding underground during daytime
To sum up, Jerusalem crickets are fascinating insects with unique physical traits and a widespread distribution in North America. Their distinct appearance and habitat preferences make them an intriguing subject to study.
Noises Produced by Jerusalem Crickets
Hissing Sounds
Jerusalem crickets produce a unique hissing noise when they feel disturbed. They create this sound by rubbing their hind legs along the sides of their abdomen1. This noise can be described as the sound of “rubbing together pieces of sandpaper”2.
Drumming and Vibrations
Another form of sound production in Jerusalem crickets is through drumming and vibrations. They generate these mating calls by drumming their abdomen against the ground1. These vibrations are then detected through the soil. This method of communication doesn’t involve the use of wings like in some other insects.
Hissing Sounds | Drumming and Vibrations |
---|---|
Caused by rubbing hind legs | Generated by drumming abdomen against ground |
Occurs when disturbed | Used for mating calls |
Sandpaper-like noise | Detected as vibrations through soil |
Note: Jerusalem crickets do not make a typical chirping sound like other cricket species2.
Reasons for Different Sounds
- Hissing: Intended for deterring predators and indicating aggression.
- Drumming: Created for mating and communication with other Jerusalem crickets.
These unique noises and methods of communication make Jerusalem crickets distinct from other insects, allowing them to interact effectively in their natural habitat.
Given this information, it’s important to remember that these creatures rely on various sounds and vibrations, such as hissing[:3:] and drumming1, for communication, mating, and defense.
Behavior and Lifestyle
Solitary Nature
Jerusalem crickets are known for being solitary creatures. They tend to live alone and interact with others primarily during mating.
- They do not form colonies or groups
- Jerusalem crickets are mostly nocturnal
Mating Rituals
When it comes to the mating rituals of Jerusalem crickets, it involves a specific sequence of sounds and behaviors.
- Males initiate mating by producing a drumming sound with their abdomen
- This sound is detected by females as vibrations through soil
Jerusalem crickets can produce a variety of sounds in addition to their mating calls:
- Hissing noise when disturbed (by rubbing their hind legs along their abdomen)
- Drumming sound as a communication method
Despite their solitary nature, these fascinating insects rely on intricate rituals and acoustic signals to locate and communicate with potential mates.
Diet and Feeding Habits
Omnivorous Diet
Jerusalem crickets are known for their omnivorous diet. These insects primarily feed on:
- Roots: They nibble on plant roots, causing damage to gardens and crops.
- Insects: They also consume, capture, and kill other insects, using their strong mandibles for this purpose.
These crickets often search for food underground or among rocks and logs.
Feeding on Decaying Organic Matter
Apart from their varied diet, Jerusalem crickets also decompose decaying organic matter. You can typically find them in:
- Dirt: Crickets break down organic matter in the soil, helping recycle nutrients.
- Compost bins: They contribute to breaking down waste material in compost piles.
In summary, Jerusalem crickets not only feed on roots and insects but also break down decaying organic matter, making them essential components of their ecosystems.
Cultural Significance and Other Names
Jerusalem crickets, also known as potato bugs, are large insects with a distinctive appearance. They have other names such as:
- Sand cricket
- Stone cricket
- Skull insect
- Qalatötö
These names often reflect their cultural, ethnic, or geographic origins. For example, they’re called “niña de la tierra” (child of the earth) in some Spanish-speaking regions.
Despite their name, Jerusalem crickets are not true crickets. Their behavior and morphology differ significantly from other cricket types. For instance, they are wingless and prefer to burrow in the soil, while many cricket species have wings and chirp using stridulation.
Jerusalem crickets are also known to emit a foul smell when threatened or disturbed. This defensive mechanism helps ward off potential predators in their natural habitat.
In some cultures, Jerusalem crickets are considered symbols of good luck, while in others, they are seen as harbingers of misfortune. This duality makes them fascinating insects for researchers and enthusiasts alike.
Noise-wise, Jerusalem crickets produce several sounds, like hissing by rubbing their hind legs against their abdomen. Mating calls are created by drumming their abdomen on the ground, which other crickets detect as vibrations in the soil.
Here’s a summary of their main features:
- Large body size (1.5-3 inches long)
- Human-like head with large mandibles
- Amber in color with dark stripes on the abdomen
- Long antennae and no wings
- Produce various sounds for communication
Overall, Jerusalem crickets, despite their misleading name, are fascinating insects with unique characteristics, making them stand out among other cricket species.

Hullo Kimberly, Your bug looks like a King Cricket from the Stenopelmatidae family, subfamily Deinacridinae, genus Australostoma. They live in borrows and tend to come out at nght when it is wet. Found in coastal NSW north to Brisbane. According to David Rentz (“Grasshopper Country”), “when handled, they produce foul-smelling anal secretions that deter predators,” so perhaps you were wise to persuade it to go outside.
BTW I am just around the lake from you at Wangi and found a huge cricket last week when moving compost onto the vegie garden, so perhaps the big crickets are on the move!
hi, just found a potato bug in my basement. Do you have any idea how it ended up inside the house? Should I take stuff in the basement apart to see if there are others or do they show up by themselves?
Thanks, Jeanette
We live in mountains outside of Sacramento, CA., near Placerville. Yesterday the pesticide man came and sprayed around the house. It’s my daughter’s home and they choose to do this. Today I found a large potato bug with a black striped abdomen struggling and almost paralyzed on patio. Obviously poisoned. It was having a very slow, excruciating death. I’ve seen the same with a praying mantis, also. Sometimes they live 2-3 days and try so hard to move. But they are still very aware of when I come and put my hand near them. They try to defend themselves.
It is a pitiful sight and it breaks my heart. I don’t like to see anything suffer a slow, debilitating death. Finally, after watching the potato bug too long, and the mantis, too, I stepped on them quickly and strongly to take them out of their pain.
The small bugs die more quickly, thank goodness. But I guess the strength of the pesticide isn’t enough to kill the large ones very fast.
My daughter says that they have to have this done because otherwise there are so many earwigs and even scorpions that come in the house. Perhaps…but I think I’d rather deal with them without the poison. It’s heartbreaking.
What else can be done?
how to control potato bugs?
We do not provide extermination advice.
It’s a Henicus monstrosus
Agree
The Jerusalem Cricket is of the genus Stenopelmatus. The Potato bug is Armadillidium vulgare. Different bugs.
Several years ago we found a potato bug in our pool. We scooped it out and put it in a zip lock bag. We didn’t know what it was and our curiosity led us to the WTB website. It was a bit more pale in color than the photos we saw on the site, but figured that was from being in the pool. The next morning we were going to throw it away and much to our surprise, it moved! It hadn’t drowned. So, we let it loose behind the wall on the backside of our property.
I found one of the Potato bugs here in Douglas Wyoming yesterday. We didn’t know what it was until I found your site.
Bug
I grew up in Pocatello Idaho and seen these quite often in the city creek and mink-creek area.They look creepy to me and was scared of them because to me they look like they wasn’t fully developed from a mother’s womb of a species I’ve never seen, having the Partially transparent legs and feet looking kinda like hands and with their big eyes!
(Bug eyes) ? Wondering if they are harmful in anyway?
I always heard that bite was poisonous
