Treehoppers are fascinating insects that can be found in various environments, often seen on plants and trees. You might have encountered these unique creatures in your garden or local park, distinctive by their enlarged pronotum, which looks like a thorn or wart. But have you ever wondered what do treehoppers eat?
These tiny insects feed primarily on plant sap, specifically from the phloem tissue within their host plants. They use their piercing mouthparts to access the sap, which provides them with essential nutrients for survival. Treehoppers are known to be selective about their food sources, as some species may be polyphagous (feeding on various plant species), while others may have a preferred host plant family or genus 1.
As a by-product of their feeding habits, treehoppers excrete a sugary substance called honeydew, which is a highly sought-after food for other insects like ants and bees. This ecological interaction showcases the intricate balance of nature and further enriches the community of organisms within their habitat. So, the next time you encounter a treehopper, you’ll know just what keeps them going in their little world.
What are Treehoppers?
Treehoppers belong to the family Membracidae, a unique group of insects often found on plants. These fascinating creatures are known for their distinct appearance, which includes a variety of unusual shapes, colors, and sizes.
The size of treehoppers usually ranges from 3 to 10mm. They come in many shapes, some examples include those resembling thorns, leaves, or even tiny animals. This rich diversity of forms helps treehoppers blend in with their plant hosts, providing an effective form of camouflage.
Now, let’s quickly explore some key features of treehoppers:
- They are plant-feeding insects, sucking sap from stems and leaves.
- Treehoppers can communicate with each other through vibrations.
- Most treehoppers have a unique structure called a “pronotum,” which extends over their main body, providing both protection and camouflage.
In a nutshell, treehoppers are intriguing insects with a wide range of shapes and sizes, belonging to the Membracidae family. Their fascinating appearance and behavior make them a unique member of the insect world. As you observe plants in your surroundings, keep an eye out for these small yet remarkable creatures.

Everyone’s outdoor space is unique, and the treehoppers you may encounter can vary depending on your location and the types of plants in your area. Keep an eye out for these amazing insects next time you’re outside, and appreciate their presence as a part of your local ecosystem.
Physical Appearance
Color and Camouflage
Treehoppers come in various colors, which aid in their camouflage. You may find them in shades of green, brown, or a combination of these, helping them blend seamlessly with the plants they reside on. For example, the Buffalo Treehopper is usually green or brown to match the leaves of its host plants.
These little insects are known for their striking and unique appearances. The Brazilian Treehopper, for instance, has a spectacular helmet-like structure with spines and intricate designs, which mimics thorny branches. This disguise helps them go unnoticed by predators.
Unique Body Features
One of the most prominent features of treehoppers is their enlarged pronotum. Commonly referred to as Thorn Bugs, their pronotum extends over their wings and abdomen, creating a protective shell that is visually similar to a thorn, hence their nickname.
Different species of treehoppers have unique body features that make them stand out. Take the Brazilian Treehopper; not only does it sport a helmet-like pronotum, but it also has strange, spindly horns protruding from it. These horns add to their overall camouflage, making them even harder to spot.
On the other hand, the Buffalo Treehopper has a smaller, more rounded pronotum, giving it a buffalo-like hump appearance. Though they don’t have the same elaborate spines as their Brazilian counterpart, their distinct shape helps them blend into their environment just as effectively.
By having these assorted physical traits, treehoppers can successfully evade predators, making the most of their color, camouflage, and unique body features.
The Diet of Treehoppers
Treehoppers are fascinating insects that might surprise you with their unique diets. For starters, they primarily feed on sap from plants. You see, these creatures possess specialized mouthparts called “stylets” which help them tap directly into a plant’s vascular system to extract nutrient-rich sap1.
- Sap: The primary source of nutrition for treehoppers is sap, which they extract from a variety of plants1.
Besides sap, treehoppers may also feed on different plant parts, depending on their species, preferences and available plant types. Here are some instances of their plant-based diet:
- Leaves: Some treehopper species are known to enjoy feeding on the leaves of a variety of plants2.
- Grasses: Grasses can serve as a fantastic food source for certain treehopper species, especially ones found in grassy habitats2.
- Plant stems: Many treehoppers will choose to consume plant stems as well, tapping into their nutrient-rich cells3.
When it comes to selecting their menu, treehoppers can be picky and particular about their food choices. For example, some treehoppers may only feed on specific plant species4. Others could be more flexible, exhibiting a polyphagous diet where they consume a wider variety of plant types4.
Though treehoppers mainly devour plant-based diets, it’s crucial to know that they can also spread diseases among plants by feeding on them and passing on pathogens3. So, while these insects are fascinating in their eating habits, they can potentially cause harm to their host plants in the process.
Predators and Defense Mechanisms
Common Predators
Treehoppers, like many other insects, have to deal with various predators in their natural environment. Some common predators that you might encounter are:
- Ants: Ants are known for their cooperative attacks on various insects, and treehoppers are no exception.
- Birds: Many bird species, such as flycatchers and warblers, prey on insects like treehoppers for sustenance.
- Geckos: These small lizards often consume insects, including treehoppers, as a primary food source.
- Wasps: Some parasitic wasp species lay their eggs inside treehoppers, eventually leading to the insect’s demise.
Defensive Strategies
To protect themselves from these predators, treehoppers have developed several defensive mechanisms:
- Mimicry: Many treehoppers bear a striking resemblance to thorns, leaves, or other elements of the plants they inhabit. This camouflage helps them avoid detection by predators.
- Vibrations: Treehoppers communicate through vibrations that travel along plant stems, allowing them to alert others in their group when a predator is nearby. This can help the entire group react and escape danger together.
In conclusion, treehoppers face a variety of predators in their everyday lives but have developed several strategies to defend themselves. Through the use of mimicry and vibrational communication, treehoppers can better evade and escape their many enemies.
Treehoppers and Symbiotic Relations
Treehoppers are fascinating insects that mainly feed on plant sap, utilizing their specialized mouthparts to pierce tree bark and access nutrients. Their saliva prevents the tree from closing the bite area, which can sometimes lead to the spread of plant diseases.
In their quest for sustenance, treehoppers also form symbiotic relationships with other insects, such as ants. These relationships can be quite complex and beneficial for both parties involved. For instance:
- Treehoppers produce honeydew, a sweet, sticky substance that ants love. In exchange for this valuable food source, ants offer protection to treehoppers from predators and parasites.
- The presence of ants can also benefit the treehopper’s host plant, as ants often protect it from other harmful insects or pests that may try to attack.
Here are some key features of treehoppers and their symbiotic relations:
- Insects involved: Treehoppers and ants
- Primary food source: Plant sap for treehoppers, honeydew for ants
- Mutual benefits: Protection for treehoppers, food for ants, and sometimes indirect protection for the host plant.
Remember to appreciate the fascinating world of insects around you, and keep in mind the significance of their symbiotic relationships.
Reproduction Cycle
Treehoppers begin their reproductive cycle by laying eggs. The female treehoppers usually lay their eggs in the living tissue of their host plant, or on the surface of the plant. You might be interested to know that some species coat their eggs with a frothy substance that hardens when dry, providing extra protection for the eggs 1.
Upon hatching, treehoppers enter the nymph stage. Nymphs look similar to adults, but they’re smaller and lack wings. As they grow, they go through multiple stages called instars, gradually developing wings and reaching adulthood.
Reproduction in treehoppers typically occurs once or more every year, leading to one or more generation per year 1. This means that treehoppers continuously ensure their species survival.
Here’s a quick summary of the treehopper reproductive cycle:
- Eggs: Laid on host plants, sometimes coated with a protective substance
- Nymphs: Hatch from eggs, go through multiple instars before becoming adults
- Reproduce: Adult treehoppers mate and reproduce, creating the next generation
- Generation: One or more generations can occur per year
It’s crucial to understand the reproduction cycle of treehoppers to gain insight into their life cycle and population dynamics. Knowing their reproductive patterns can also help you manage their presence in your garden or agricultural fields.
Treehoppers and Their Impact on Environment
Positive Impact
Treehoppers, belonging to the Insecta class, play a vital role in their ecosystem. They help in pollination and serve as a food source for various predators like birds, spiders, and other insects.
For example, the Three-Cornered Alfalfa Hopper can benefit from eating plant sap because it helps improve the overall health of the plant. Similarly, Brazilian Treehoppers can have a positive influence on vegetation by increasing the nutrient cycling in the ecosystem.
Negative Impact
On the other hand, treehoppers can also cause damage to plants. They feed on sap, weakening the plant and sometimes transmitting diseases. True Bugs and Buffalo Treehoppers can cause significant damage to crops and trees, reducing yield and overall plant health.
For instance, the spread of diseases via insects like Flies and Brazilian Treehoppers can lead to financial loss if it affects agricultural production. It is crucial for farmers to monitor and manage treehopper populations to minimize the negative impact on the environment.
As you can see, treehoppers have both positive and negative effects on the environment. Maintaining a balance in their population is essential to avoid adverse consequences and support ecosystem health.

Interesting Facts
Treehoppers, belonging to the order Hemiptera, are fascinating creatures known for their unique appearances and behaviors. They are found all around the world, with approximately 3,200 species known to exist. Let’s explore some of their interesting features and characteristics.
Treehoppers feed primarily on plant sap, using their sucking mouthparts to pierce the bark of trees and extract the sap. Their saliva contains certain enzymes that help prevent the tree from healing the pierced area, allowing them to feed freely. Interestingly, some treehoppers, like the three-cornered alfalfa hopper and buffalo treehopper, are considered agricultural pests as they can cause damage to alfalfa, soybeans, and apple trees.
In terms of communication, treehoppers employ a unique method that involves vibrating their wings. This form of communication helps them signal others in their group when they perceive potential threats. Alfred Keller, a renowned entomologist, has studied these insects extensively and contributed greatly to our understanding of their biology.
Here are some additional interesting features of treehoppers:
- Stictocephala is a genus of treehoppers with species that are commonly called buffalo treehoppers due to their humpbacked appearance.
- Treehoppers are related to cicadas and leafhoppers, sharing features such as short, bristle-like antennae and three-segmented feet (tarsi).
- While not known for their speed, treehoppers are able to hop quickly and fly when necessary, using their notably short wings.
- The oil they produce as a byproduct of feeding can be important for other species, such as ants that feed on it and even protect treehoppers from predators in exchange for this valuable resource.
As you can see, treehoppers are fascinating insects with intriguing characteristics and a unique method of communication. Their diverse appearances, feeding habits, and relationships with other species make them an interesting topic of study and discussion.

Traditionally consumed in Mexico and elsewhere
Seasons Greetings one and all,
The traditional name ‘Periquitos,’ meaning “Parrakeets,” is what this insect goes by (at least that’s the ethno-name; I don’t know which particular species of tree-hoppers it’s applied to.) They were consumed in Mexico and still might be, but I don’t think they’re as popular as chapulines, gusanos, or escamoles — grasshoppers, caterpillars, or ants [again, particular species thereof].
Some tree-hoppers are also consumed in South America; I once read about an ethnologist who hurt his mouth on an insect’s thorn.
This species is in the genus Umbonia, but the exact species is difficult to nail down from this photo.
Hi,
I have now found images of this and similar species on several sites, which give the genus as Membracis, and this also gives me confidence that my other image (with the nymphs) also shows a Membracis, but I would still like to find which species they are.
Peter
I have photographer a quite similar one in Brazil, Northern Pantanal: http://pic.atpic.com/2233582
And I have posted it too. I haven’t find its exact ID either…
This is most likely Mebracis bucktoni.
Sorry, meant most likely Membracis bucktoni.
Thank You! It is such a beautiful insect I had to know what it was called. You guys rock!
Just found the same insects all over my carrots. Does anyone know how to get rid of this pest?
*I live in Dallas, Texas
Looks like Glossonotus:
