Mole crickets are fascinating creatures that live mostly underground, and you might be wondering what these insects look like. The primary features of a mole cricket include their light brown color and enlarged forelegs, which help them dig through soil efficiently. Adult mole crickets are about 1.5 inches in length, making them quite easy to spot if you come across one.
These insects go through various life stages, and their appearance changes with each stage. While nymphs resemble the adults, they are significantly smaller and lack wings. As they grow and develop, their wings eventually emerge, and they reach their adult size.
Now that you know the basics of what mole crickets look like, you can easily identify them when you come across these unique insects. Understanding their appearance is important for controlling their population, as they can cause damage by tunneling through soil and uprooting grass and crops.
Identifying a Mole Cricket
Comparison with Other Crickets
Mole crickets are quite different from other crickets, such as field crickets and house crickets. Let’s take a closer look at their characteristics to help you identify them.
Mole crickets are typically around 1.5 inches long, with a cylindrical body covered in short hairs. They display a tan to light brown color, which allows them to blend in well with their underground environment. You may also notice their two long, thin antennae on their heads.
Unlike house and field crickets, mole crickets have wings. Their hind legs are strong and adapted for jumping, but not as prominent as those of grasshoppers. A striking feature of mole crickets is their enlarged shovel-like forelegs, which are specialized for digging and burrowing. These insects also have two small, finger-like cerci at the end of their abdomen.
Let’s compare the features of mole crickets with other cricket types:
|Size and Appearance
|Cylindrical, 1.5 inch
|Oval, 0.5-1 inch
|Oval, 0.6-0.9 inch
|Tan to light brown
|Black or brown
|Strong for jumping
|Strong for jumping
|Strong for jumping
|Enlarged for digging
To summarize, when identifying a mole cricket, pay attention to its:
- Tan to light brown color
- Long, thin antennae
- Strong hind legs, less prominent than grasshoppers
- Enlarged forelegs for digging
- Two finger-like cerci
- Dense covering of short hairs
By noting these specific characteristics, you can easily distinguish mole crickets from other common cricket types.
Life Cycle and Behavior
Mole crickets are fascinating insects with a unique life cycle and behavior. Let’s explore their journey from eggs to adulthood, along with some of their interesting behaviors.
In the beginning, female mole crickets lay clusters of 25-60 eggs in an egg chamber in the soil. They go through an incomplete metamorphosis, meaning they don’t have a typical larval stage.
Once the eggs hatch, nymphs emerge. They look like miniature versions of adult mole crickets but without wings. Nymphs undergo several molts before becoming adults, with each molt making them larger and closer to their adult form.
As nocturnal creatures, mole crickets are mostly active at night. Males use their unique song to attract females for mating, something you’d notice by the loud chirping sound they produce.
Some key features of mole crickets include:
- Enlarged, mole-like digging front legs
- Short, dense hairs covering the body
- Adults have wings and can fly, although clumsily
Remember, mole crickets spend most of their lives underground, tunneling through the soil to forage for food and create their habitats.
In conclusion, the life cycle of mole crickets from eggs to egg-laying adults showcases a fascinating journey filled with unique behaviors and adaptations. They play a significant role in the ecosystem by aerating the soil and recycling organic matter, all while living their lives mostly out of our sight.
Habitats and Distribution
Mole crickets are insects that primarily reside in tunnels and burrows, which they create in the soil. They are commonly found in lawns, turfgrass, and golf courses. Their preferred habitat is often sandy soil, which makes it easier for them to dig their tunnels. Some of the different regions where mole crickets can be found include Australia, North America, and the southeastern United States.
In North America, there are both native and non-native species of mole crickets. The native species include the northern mole cricket, western mole cricket, and prairie mole cricket. Their distribution ranges from the eastern and central states of the United States to parts of Mexico and Canada .
On the other hand, the non-native species in Florida consist of the tawny, southern, and shortwinged mole crickets . These species are more likely to be found in the southeastern United States.
As you might have guessed, mole crickets are quite adaptable to different habitats. However, if you want to prevent them from infesting your lawns and gardens, consider the following:
- Pay attention to the type of soil. Sandy soil is more conducive to mole cricket infestations.
- Regularly monitor your lawns and gardens for signs of mole cricket activity to catch any infestations early on.
Remember that understanding the habitats and distribution of mole crickets can be useful in managing their populations and protecting your landscapes. Keep an eye on your property and act promptly if you notice any signs of mole cricket activity.
Mole Cricket Species
Mole crickets are insects that belong to the family Gryllotalpidae and the order Orthoptera. There are a few common species you might encounter, such as the tawny mole cricket, southern mole cricket, and Neoscapteriscus vicinus.
The tawny mole cricket is light brown, with a velvety appearance. They are known for their ability to cause damage to turfgrass and pastures. Some key features of tawny mole crickets include:
- Size: 1.2 to 1.4 inches in length
- Forewings: Pale and translucent
- Habitat: Prefer sandy soils
The southern mole cricket has a darker color and is slightly smaller than the tawny mole cricket. They too can cause damage to turfgrass, pastures, and vegetable seedlings. Here are some characteristics of southern mole crickets:
- Size: 1 to 1.2 inches in length
- Forewings: Darker with smoky brown spots
- Habitat: Varied soil types
Neoscapteriscus vicinus, also known as the short-winged mole cricket, is similar in appearance to the southern mole cricket. However, it prefers to live in wetter environments. Some features of this species are:
- Size: 1 to 1.2 inches in length
- Forewings: Shorter and dark brown
- Habitat: Wet soils, often near water sources
Mole cricket species have experienced convergent evolution, meaning they have developed similar physical features to adapt to their environments, even though they may come from different lineages.
Here’s a comparison table to help you understand the differences between these three species:
|Tawny Mole Cricket
|1.2 – 1.4 in
|Pale and translucent
|Southern Mole Cricket
|1 – 1.2 in
|Darker, brown spots
|Varied soil types
|1 – 1.2 in
|Shorter, dark brown
By understanding the taxonomy and characteristics of these mole crickets, you can better identify the species you encounter and determine the potential risks they pose to your garden or lawn.
Feeding and Damage
Specific Damage to Plants
Mole crickets primarily cause damage by tunneling through the soil near the surface, which can negatively impact the roots of your plants and grass. This tunneling can disturb the grass roots, leading to dead or dying grass in the affected area. Most often, you’ll notice brown and die patches in your lawn as a telltale sign of an infestation.
Mole cricket damage is particularly prevalent in certain grass types such as bermudagrass, where they feed on its roots. The damage rendered by the mole cricket manifests in the form of weakened and dying patches of grass, making it easier to spot an infestation.
Here’s a brief comparison of mole cricket damage impact on different plants:
- Bermudagrass: High susceptibility, extensive root damage
- Other grass types: Moderate susceptibility, varying degrees of root damage
- Non-grass plants: Low susceptibility, minimal damage
To help recognize and manage mole cricket damage, follow these simple steps:
- Look for telltale signs like brown and die patches in your lawn.
- Check for tunneling and disturbances in the soil near affected plants.
- Implement control measures such as soapy water drench to flush out the mole crickets.
By identifying the signs early and taking appropriate action, you can prevent further damage to your plants and ensure a healthy, thriving garden or lawn.
Control and Prevention
Mole crickets can be a real pest in your turf, causing unsightly damage and costly maintenance. Luckily, there are several ways to control them and prevent further infestation.
First, let’s talk about some signs that may indicate mole cricket activity:
- Raised, tunnel-like burrows in your lawn
- Uneven, spongy turf
- Areas of brown or dead grass
If you notice any of these signs, it’s time to take action. A simple yet effective method in monitoring mole cricket presence is the soapy water drench. Just mix water and dish soap, then pour it over suspect areas. The soapy solution will irritate mole crickets and force them to surface. Clemson Information provides a description of this technique.
Now let’s move on to some treatment options to control mole crickets:
- Insecticides: Carbaryl is a popular chemical treatment for mole crickets. Apply it to affected areas according to the manufacturer’s instructions.
- Baits: Both chemical and non-chemical baits can help eliminate mole crickets. Place them strategically around your turf.
- Biological controls: Beneficial nematodes are an eco-friendly alternative, which will prey on the mole crickets without harming your lawn.
In addition to treatments, it’s essential to implement preventative measures:
- Maintain healthy turf by regularly watering, fertilizing, and mowing.
- Keep an eye out for mole cricket activity during their peak seasons, usually from late spring to early summer.
- Encourage natural predators, such as birds or parasitoid wasps.
Remember, it’s essential to monitor your lawn, spot signs of mole crickets early, and take swift action. With these strategies, you can keep your turf healthy and mole cricket-free.
Other Interesting Features
Mole crickets have a distinctive appearance that sets them apart from other cricket species. Their front legs are highly modified, making them efficient at digging through soil. You may also notice their unique claws which aid in their subterranean activities.
They belong to the family Gryllotalpidae within the order Orthoptera, which also contains grasshoppers and other cricket species. Despite their name, mole crickets are more closely related to grasshoppers, as both are members of the same order. Here are a few fascinating characteristics of these intriguing insects:
- Size: Adult mole crickets measure about 1 1/2 inch in length.
- Omnivorous habits: Mole crickets are omnivores, feeding on both plant material and other insects.
- Flight capabilities: Although clumsy in flight, these creatures are effective at flying at night for short periods.
- Interesting reproductive behavior: Male mole crickets build mud chambers to amplify their mating calls, attracting females for mating.
Their diet consists of grasses, organic matter, and other insects, making them both predatory and herbivorous. Despite being relatively harmless to humans, mole crickets can cause damage to turfgrasses, pastures, and vegetable seedlings. As a result, they are often considered an invasive pest, especially if their population gets out of control.
Mole crickets have a few natural predators, including parasitic wasps. The adult wasp lays its eggs on individual mole crickets, and upon hatching, the larva feeds on the cricket’s blood, eventually leading to the cricket’s demise (source).
In conclusion, mole crickets showcase a range of intriguing features that distinguish them from other insects, such as their unique front legs, burrowing abilities, and diverse diet. So next time you come across one of these peculiar creatures, take a moment to appreciate their fascinating characteristics.

Hi! Could you please help to identify this freaky looking bug that got stuck in my fish bowl outside? It has 4 main legs and 2 short upper legs, no wings. This one is only 4cm long but we have seen one that is about 7cm long.
We are certainly curious about how this Mole Cricket got stuck in your fish bowl with what appears to be an artificial koi. Mole Crickets are common insects that can be found in many places around the world. It is one of our most frequent identification requests from military troops stationed in Afghanistan and other places in the Middle East. Mole Crickets live underground, but many species are capable of flying and they are sometimes attracted to lights.
Letter 4 – Mole Cricket from Australia: Rescued from Drowning
This was in my pool
Location: Perth, Western Australia, Southern Hemisphere, South Pacific, My swimming pool.
January 3, 2011 2:04 am
Hi, My name is Seb from Perth, Western australia.
It’s very hot here at the moment.
The photo posted is the second one of these I’ve seen in the space of a fortnight.
On the first encounter I was working on my bike in the shed and one of these was more or less trying to attack me?
I can confirm it can fly.
Anyway my dad took it away to the swamps later that night for his walk.
The second one was in my pool pretty much drowning so I rescued it with our brush.
I noticed it was not only trying to attach itself to the brush, but it was biting at the bristles!
Anyways I couldnt completely get it out with the brush so I scooped it up with the container, hence the water.
I was abit afraid of putting my hand any closer for a better photo… lol.
After taking the photo, it was released to the front garden. God forbit its actually an invasive species not indigenous to this region.
Im guessing because of its rear spines, its part of the cricket family?
We have a relatively large veggie patch wich at night time seems to come alive. We can hear 2 or 3 different types of frogs etc which I think should be part of a healthy ecosystem? Also lots of various plants planted around the walkways etc.
I do hope someone can help to identify this.
Kindly thanking you in great anticipation.
Signature: Thanks, Seb
This is a Mole Cricket and they do fly. They are subterranean insects that for some reason, perhaps the pool lights, are frequently found in swimming pools. Mole Crickets, which resemble one another even when the are different species, are found worldwide. The Brisbane Insect website has a lengthy page on the Mole Cricket.

My daughter found this on its back and asked, ”Is it a monster?”
Up close it certainly looks that way with a prawn/lobster like head and beetle like body. It has two stubby front limbs that are flattened and spiny at the ends.
It was found in my back yard and aside from, ’what is it?’ I’d also like to know whether it is friend or foe (I never know in Australia, most things here will kill you!)
This is a Mole Cricket, a subterranean dweller that uses it front legs to tunnel underground. Interesting, exactly one year ago, submissions of Mole Crickets from Slovenia and Australia prompted us to declare the Mole Cricket the Bug of the Month for February 2012.
Thank you for the prompt response, what a fantastic resource you run, I’ll bookmark your site and send you any more interesting finds.
