Tree crickets are fascinating creatures that you might not see often, but you’ve likely heard their distinctive chirps. They don’t live on the ground like their more common cousins; instead, they make their home in trees, bushes, and tall plants a foot or more above the ground. Their pale green bodies help them blend into their surroundings, making them difficult to spot but still a vital part of the ecosystem.
The diet of tree crickets is an essential part of their lives, as they control many pests, thus providing a natural balance in gardens and forests. Their primary food sources include aphids, scale insects, and other small plant pests, which is why tree crickets are considered beneficial insects. In fact, in a Michigan State University study, they were even observed eating the eggs of an apple pest called the codling moth.
Now that we’ve learned where tree crickets live and what they eat, it’s essential to understand their role in maintaining a healthy ecosystem. By feasting on various plant pests, they help protect plants from damage and keep our gardens and forests thriving. So next time you hear the faint chirps of a tree cricket, take a moment to appreciate the critical work they’re doing to preserve our natural environment.
What Are Tree Crickets
Tree crickets belong to the family Gryllidae and are part of the subfamily Oecanthinae. These insects are typically pale green and small, which allows them to blend in with their surroundings in trees, bushes, and tall plants. They are primarily found in the order Orthoptera, which also includes crickets, katydids, and grasshoppers.
As their name suggests, tree crickets mainly reside in trees rather than on the ground. You can find these fascinating creatures throughout various continents, regions, countries, and even islands. In the animal kingdom, tree crickets fall under the invertebrate class.
Different genera of tree crickets exist, with numerous species within each group. All of them share similar features, such as having two compound eyes and delicate bodies. Here are some of the main characteristics of tree crickets:
- They belong to the subfamily Oecanthinae
- They are usually pale green in color
- They possess compound eyes to help them navigate their environment
- They inhabit trees, bushes, and tall plants
Tree crickets are beneficial for the environment because they feed on plant pests like aphids and scale insects. For example, research has shown that tree crickets have been observed eating the eggs of a notorious apple pest – the codling moth. Embrace these fascinating creatures as friends to your garden!
Anatomy of Tree Crickets
As you explore the world of tree crickets, it’s essential to understand their anatomy. These small, delicate creatures have a unique body structure that allows them to thrive in their natural habitat.
Head and Antennae
The head of a tree cricket holds two large, compound eyes, which help them navigate their environment. Between these eyes, you’ll find their long antennae. These antennae are essential for detecting food, mates, and predators, making them a critical part of the cricket’s anatomy.

|Flesh and skin
|Flesh and juice
As omnivores, tree crickets have their share of predators too. Birds, spiders, and some larger insects consider them a tasty treat. Given their dietary versatility, tree crickets play an important role in the food chain, both as hunters and prey.
By understanding the feeding habits and preferred foods of tree crickets, you might find it fascinating to observe them in their natural habitat or even appreciate their beneficial effects on your garden’s ecosystem.
Tree Cricket Behavior
Tree crickets are fascinating creatures with unique behaviors. In this section, we will explore some aspects of their daily lives, focusing on their eating habits, chirping, and nocturnal nature.
When it comes to their diet, tree crickets are primarily insectivores. That means that you typically find them feasting on small insects such as aphids, scale insects, and ants. Occasionally, they may also indulge in plant matter like leaves and flower buds.
You might be curious about their chirping sound which is an essential part of tree crickets’ behavior. Male tree crickets produce this sound to attract female mates. The chirping is made by rubbing their wings together, creating a high-pitched sound. So, if you ever hear a tree cricket’s song, it’s likely a male serenading nearby females!
Speaking of their activities, tree crickets are mostly nocturnal. This means that they are active during the night and rest during the day. As a result, you’re more likely to observe their various behaviors, such as feeding and chirping, under the cover of darkness.
In summary, tree crickets are fascinating creatures with specific eating habits, unique chirping sounds, and a preference for nighttime activity. Their insectivorous diet and nocturnal nature make these small insects important for maintaining the balance in ecosystems. Next time you hear a chirping sound during a warm night, you’ll know that it might just be a tree cricket singing its heart out.

There are various species of tree crickets, each with their unique features and characteristics. These insects belong to the subfamily Oecanthinae and are widely distributed around the world.
One example is the Snowy Tree Cricket (Oecanthus fultoni). It is renowned for its distinct song that is often referred to as the “temperature cricket.” You can even estimate the temperature by counting the number of chirps it produces in 13 seconds and then adding 40 to the total count.
Other species of tree crickets include:
- Narrow-winged Tree Crickets (Oecanthus niveus)
- Four-spotted Tree Crickets (Oecanthus quadripunctatus)
- Two-spotted Tree Crickets (Neoxabea bipunctata)
Some common features among these species are:
- Delicate, pale green bodies that blend in with their surroundings
- Long and thin antennae
- Round or flattened heads
- Wings forming protective flaps on the sides of their bodies
In their natural habitat, tree crickets live in trees, bushes, and tall herbaceous plants, typically about a foot above the ground. Their diet mainly consists of small, soft-bodied insects like aphids, but they are known to be omnivorous and may also feed on fruits and leaves.
When it comes to comparing these species, it is essential to focus on their physical characteristics and songs. A comparison table highlighting the differences between the Snowy Tree Cricket and the Four-spotted Tree Cricket is provided below:

|Warblers, flycatchers, shrikes
Unfortunately for tree crickets, they face many threats in their natural habitats. By understanding their predators, you can better appreciate the role tree crickets play in maintaining the balance of their ecosystem.
Tree Crickets and Humans
Tree crickets are fascinating creatures that play a role in nature and can have various interactions with humans. For example, some species of tree crickets serve as a valuable food source for both humans and pets. Edible crickets are known for their nutritional benefits, and they can even be farmed for sustainable utilization.
However, not every interaction with tree crickets is positive. While house crickets, camel crickets, and mole crickets are among the species that humans may encounter, these crickets can sometimes be considered pests. They might damage your property or invade your living spaces, causing discomfort.
To better understand how tree crickets relate to their human neighbors, let’s take a closer look at their dietary preferences:
- House Crickets – These common crickets are often omnivorous, meaning they’ll consume plant material and small insects, including greens.
- Camel Crickets – Also known as spider crickets, they are omnivorous as well, but they prefer a diet of fungi and decaying plant matter.
- Mole Crickets – These burrowing crickets are mostly herbivorous and tend to feed on grasses, roots, and other organic materials.
Here’s a quick comparison table of these cricket species:
|Usability as Pet Food
|Fungi, Decaying Plant Matter
While tree crickets can be a nuisance as pests, they can also serve as a valuable pet food source. Insect-eating pets like reptiles and amphibians can benefit from the protein and nutrients that crickets provide. Just be sure to select the appropriate cricket species for your pet’s needs and be aware of any potential issues.
Overall, understanding the relationship between tree crickets and humans can help you better appreciate their role in nature and make informed decisions about managing pests or using these insects as a sustainable pet food source. Remember, it’s ultimately up to you to determine whether these interactions are beneficial or detrimental to your specific situation.
Reproduction in Tree Crickets
When it comes to the reproduction process of tree crickets, several stages are involved. In this brief section, you will learn about these stages, including the roles of male and female tree crickets, and how they ensure the survival of their species.
Female tree crickets lay their eggs in various places, such as plant stems or the bark of trees. This provides protection and an ideal environment for the eggs to develop. Over time, these eggs hatch into the next stage of their life cycle: the larvae.
Females and Male Crickets
In the reproduction process, female tree crickets play the role of laying eggs, while male tree crickets are responsible for attracting a mate. Male tree crickets produce a unique, high-pitched sound to attract females. Once they have found a mate, they will fulfill their role in the reproductive process.
Adult Crickets and Larvae
After hatching from the eggs, the larvae go through several stages called instars before becoming adult tree crickets. As they grow and develop, the larvae feed on soft-bodied insects like aphids and scale insects to gain strength and energy source. Adult tree crickets continue to feed on these beneficial insects, which aids in maintaining a balanced ecosystem.
To sum it up, tree cricket reproduction involves multiple stages and crucial roles performed by both male and female crickets. This delicate, fascinating process ensures the continued existence of this unique insect species.

A bug for you
In the past week I have noticed quite a few of these little bugs running around. They remind me of a grasshopper so at first I was a little affraid that they are going to eat some of my plants, but then I noticed they just kind of ran around the leaves, reminded me of lady bugs so then I thought that maybe they would be great for me to keep around for aphids in my greenhouse. Know any information on them? Or atleast what it is?
This is a Tree Cricket in the genus Oecanthus. Immature Tree Crickets will nibble leaves and young shoots, but adults are important predators. They eat Aphids and Caterpillars. The added benefit is that they “sing”.

any idea what bug this is?
Location: Sierra Nevada foothills, California
December 2, 2010 9:41 pm
This picture was posted Nov. 29. The bug was about 3/4 of an inch long, very flat to the ground, color is pretty accurate. The picture was taken in the foothills of the western face of the Sierra Nevada in California. I don’t know if it was in an urban setting or rural or what. I searched through Kaufman Field Guide to Insects of North America and didn’t find it. And the person who posted the picture didn’t find it in a Sierra Nevada field guide. Maybe we both overlooked it. Do you have any idea what type of bug this is?
Signature: Thanks, Willie
This is a Tree Cricket in the genus Oecanthus, possibly the Western Tree Cricket in its brown form, Oecanthus californicus, based on this image posted to BugGuide. There is some interesting information posted to BugGuide on the Snowy Tree Cricket or Thermometer Cricket, Oecanthus fultoni.

Subject: Whats That Bug
Location: Northeast Ohio
September 24, 2015 4:13 am
Photo taken in Northeast Ohio yesterday, do you know what this bug is? A second question for you: my four-year-old is a prolific bug catcher. Do you have any advice on a bug that might make a good indoor “pet” that she could keep alive for a while indoors?
This is a Tree Cricket, and we believe it is a male Two Spotted Tree Cricket, Neoxabea bipunctata. We believe this Tree Cricket is an excellent candidate for an indoor pet, and it can be kept in a small aquarium used as a terrarium with a screened to keep the Tree Cricket confined. According to BugGuide: “Two-spotted Tree Cricket, can be found on a wide variety of vegetation including (but not restricted to): Grapevine, Sunflower, Maple Tree, White Pine Tree, Apple Tree, Post Oak Tree. They are generally high on tall plants or in trees” and it “Presumably feeds on plants.” In addition to being interesting to watch, there is an additional advantage to keeping a Tree Cricket as a pet. According to BugGuide: “Males sing mostly at night: a 10-second trill followed by several seconds of silence, then a trill again.” We believe Tree Crickets generally live a single season, and their lives are often cut short by an early frost. Keeping a pet Tree Cricket should extend the life of the individual by providing a more temperate environment free of killing frosts.
Awesome information! Thank you very much for taking the time to email!
