Grasshoppers are fascinating insects that can be found all over the world. They are known for their unique jumping ability, which is achieved primarily through their highly-specialized legs. When observing a grasshopper, it’s easy to notice that they have three pairs of legs, making a total of six legs.
Each pair of legs has a specific function and adapts to perform different tasks. The first and second pair of legs are relatively small, mainly responsible for walking and holding onto various surfaces. Meanwhile, the hind pair is much larger and designed for jumping, allowing the grasshopper to quickly propel itself over considerable distances.
The anatomical structure of grasshopper legs is quite intricate. The hind legs are well-equipped with muscles, allowing for powerful jumps to evade predators or reach new feeding grounds. These legs also possess distinctive features such as enlarged femur and tibia, which further contribute to their impressive jumping capability.
Grasshopper Basics
Anatomy
Grasshoppers are insects that belong to the suborder Caelifera. They have six legs, with the hind pair being much larger than the first and second pair due to their adaptation for jumping1. Their body is divided into three main parts: head, thorax, and abdomen2. They also possess two pairs of wings, differing in shape, structure, and function1.
Grasshoppers have compound eyes, providing them with a wide field of vision3. Male grasshoppers may have special structures on their wings for producing sound3.
Color and Size
Grasshopper species can vary in color, typically being brown, green, or a combination of both4. Their color can serve as camouflage, making them harder for predators to detect4.
- Males: Usually smaller than females3
- Females: Larger than males; possess sharp points at end of abdomen for laying eggs3
In general, female grasshoppers are larger than males. For example, females have sharp points at the end of their abdomen that help them lay eggs underground3.

Feature | Male Grasshoppers | Female Grasshoppers |
---|---|---|
Size | Smaller | Larger |
Wing Structure | Special structures for sound3 | None mentioned |
Abdomen | None mentioned | Sharp points for laying eggs3 |
Legs and Jumping Capabilities
Number of Legs
Grasshoppers, like all insects, have six legs. These legs are divided into three pairs, with each pair serving a different function in the grasshopper’s movement and activities.
Functions of Hind Legs
The most notable of these legs are the hind legs, which are much larger and stronger than the other two pairs. These legs are specifically adapted for jumping, allowing grasshoppers to cover great distances in meadows and fields. Key features of hind legs include:
- Enlarged femurs
- Distinctive markings and coloration
- Long tibia with spines for gripping surfaces
Jumping Mechanism
Grasshoppers use their hind legs to generate a powerful force for jumping. Their strong muscles and unique joint structure allow them to create an acute angle between the thigh and shin, enabling a catapult-like action. Here’s a brief overview of how grasshoppers jump:
- Grasshopper contracts powerful leg muscles.
- Acute angle between thigh and shin is created, storing energy in extensor muscles.
- Rapid release of stored energy propels the insect forward with great force.
In addition to their hind legs, grasshoppers also use their wings for short flights, further enhancing their mobility in their natural habitat.
Grasshoppers’ jumping capabilities, combined with their six legs and strong mandibles, make them an agile and versatile insect that can thrive in various environments, ensuring their survival and continuation as a species.
Grasshopper Diet and Predators
Feeding Habits
Grasshoppers are primarily herbivores. They consume various plants for their diet, including leaves, flowers, and stems. Their food preferences may differ depending on the species. Some examples of plants they eat are:
- Grasses
- Shrubs
- Trees
Grasshoppers require protein to grow and molt, which they usually obtain from the plants they consume.
Common Predators
Grasshoppers have numerous predators in their environment. These predators can be classified into three categories – arthropods, birds, and mammals. Some common predators include:
- Arthropods: Spiders, wasps, and robber flies
- Birds: Turkeys, chickens, and other insectivorous birds
- Mammals: Rodents and some reptiles
A comparison table of common grasshopper predators:
Predator Type | Examples |
---|---|
Arthropods | Spiders, wasps |
Birds | Turkeys, chickens |
Mammals | Rodents, reptiles |
In the past, flocks of turkeys and chickens were sometimes used for grasshopper control due to their effectiveness in reducing grasshopper populations (source).
Lifecycle and Reproduction
Life Stages
Grasshoppers undergo a process called gradual metamorphosis, with three main stages:
- Egg: It all starts here. Females lay the eggs in a special structure called a pod, in the soil or vegetation.
- Nymph: Hatched from eggs, these immature grasshoppers resemble the adults but have no wings. They go through a series of molts, growing larger each time.
- Adult: Finally, when they develop fully functional wings, they are considered adults.
Mating and Egg Laying
Grasshoppers mate after becoming adults, and their reproductive organs get activated:
- Females: They possess an ovipositor, enabling them to lay eggs in the habitat, typically soil or vegetation.
- Males: Their role is to fertilize the eggs. They use special structures to hold and position the females during mating.
For example, the Eastern lubber grasshopper lays eggs in a pod, usually in a place with lots of food and an adequate environment for the nymphs to thrive.
Features | Nymph | Adult |
---|---|---|
Wings | Not functional | Fully functional |
Size | Smaller | Larger |
Reproductive organs | Not active | Active |
In summary, grasshoppers have a simple life cycle, starting as eggs, developing into nymphs, and finally becoming adults capable of reproduction. Their mating and egg-laying habits are vital for their survival in a variety of habitats.
Notable Grasshopper Species
Differential Grasshopper
The Differential Grasshopper is a shiny, brownish-yellow insect, growing up to 1¾ inches long. Adults exhibit a unique feature:
- Hind legs with black chevrons (v-shapes)
Lubber Grasshopper
The Lubber Grasshopper is well-known for its large size and vibrant coloration. Some interesting characteristics include:
- Inability to fly due to small wings
- Can excrete a toxic foam as a defense mechanism
Red-Legged Grasshopper
Red-Legged Grasshoppers sport a distinctive feature:
- Bright red hind legs, contrasting with a green or brown body
Two-Striped Grasshopper
Texas A&M University’s resource highlights the Two-Striped Grasshopper’s features:
- Yellow body with two dark stripes
- Good short-distance flyers, supported by long hind legs
Grasshopper Species | Color | Size (approx.) | Unique Features |
---|---|---|---|
Differential Grasshopper | Brownish-yellow | 1¾ inches | Black chevrons on hind legs |
Lubber Grasshopper | Various | Large | Toxic foam, small wings |
Red-Legged Grasshopper | Green or brown body, red legs | Medium | Red hind legs |
Two-Striped Grasshopper | Yellow with dark stripes | Medium | Good short-distance flying ability |
Grasshopper Management and Impact
Impact on Food Crops
Grasshoppers are known to have a significant impact on food crops. They can consume up to 50% of their body weight in forage daily, leading to reduced crop yields.
For example:
- Wheat
- Corn
- Soybeans
This consumption has adverse effects on farmers and the agriculture industry.
Methods of Control
There are several methods available to control grasshopper populations, both chemical and non-chemical. Here’s a comparison table:
Method | Pros | Cons |
---|---|---|
Chemical control | Effective, faster results | Potential environmental harm, harmful to non-target species |
Biological control | Environmentally friendly, targets specific species | Slower results, may require higher initial investment |
Some of the common biological control methods include:
- Predators: Birds, blister beetles, and robber flies.
- Fungal and bacterial diseases
- Parasites
For a more natural approach, maintaining a healthy ecosystem with a diverse range of predators and natural enemies assists in managing grasshopper populations.

Looks like a female Lamarckiana (Pamphagidae.)
From what I’ve read over the years, Acridids (Acrididae is the scientific name of the grasshopper family) are are the most commonly consumed family of insects around the world.
This one definitely looks like a nymph. Might well be the genus Schistocerca, which are generally the locusts.

Thank you so much – I wouldn’t even have known that it is an immature one ! Based on that, I’m leaning toward him being Eyprepocnemis plorans – appears to be the most similar in my book.
We believe it is a nymph because of the very short wing pads which we believe will eventually develop into wings capable of flight as the insect continues to molt and grow.
Awesome – I wasn’t sure if that was patterning and he would turn out to be a Bush Hopper. I do wish I’d discovered you clever people before now !
Cathy try http://www.ispot.org.za/ I’m sure you’ll get your answer there.
Hi, I’m in the Vega Baja area of Spain. One of the “unknown grasshoppers” was rescued from my pool this morning. Once he had dried off in the sun we put him out of view from the birds.
Strange little creature. Seemed more like a stick insect than grasshopper.
