California’s Mediterranean climate and varied geography create distinct grasshopper populations from coast to desert. Understanding the Types Of Grasshoppers In California helps you identify these insects whether you’re a gardener, hiker, or just curious about local wildlife.
Grasshoppers are everywhere in California. You see them in your backyard, along hiking trails, and in agricultural fields. They come in many colors, sizes, and behaviors. Some are harmless, while others can damage crops.
This guide covers the most common species you’ll encounter. You’ll learn how to identify them, where they live, and what they eat. Let’s jump right in.
Types Of Grasshoppers In California
California hosts over 200 grasshopper species. That’s a lot of jumping insects. But you don’t need to memorize all of them. Focus on the ones you’re most likely to see.
Grasshoppers belong to the order Orthoptera. They have strong hind legs for jumping, two pairs of wings, and chewing mouthparts. Most are active during warm months.
Common California Grasshopper Species
Here are the grasshoppers you’ll encounter most often across the state.
Differential Grasshopper
This is one of the largest grasshoppers in California. Adults reach up to 1.75 inches long. They’re brown or olive-green with black markings on their hind legs. Look for a distinctive herringbone pattern on their thighs.
Differential grasshoppers prefer weedy areas and crop fields. They’re common in the Central Valley. They eat a wide variety of plants, including alfalfa, corn, and vegetables. In large numbers, they can cause serious damage to farms.
You’ll see them from late spring through fall. They’re most active during hot, dry weather.
Red-Legged Grasshopper
This species gets its name from the reddish-orange color on its hind legs. They’re medium-sized, about 1 to 1.5 inches long. Their body is brown or gray with a pale stripe down the back.
Red-legged grasshoppers live in grasslands and open areas. They’re found throughout California, from the coast to the mountains. They eat grasses and forbs, but they rarely cause major crop damage.
These grasshoppers are strong fliers. When disturbed, they fly several feet before landing again.
Two-Striped Grasshopper
Look for two pale yellow stripes running from the head to the wing tips. That’s how you identify this species. They’re about 1.25 to 1.75 inches long. Their color ranges from green to brown.
Two-striped grasshoppers prefer moist areas near streams, irrigation ditches, and wetlands. They’re common in the Central Valley and coastal regions. They eat grasses, sedges, and some crops like alfalfa.
These grasshoppers are less common in dry desert areas. They need moisture to survive.
Migratory Grasshopper
Despite the name, this species doesn’t always migrate. But when conditions are right, they can form large swarms. They’re medium-sized, about 1 to 1.5 inches long. Their color varies from green to brown to yellow.
Migratory grasshoppers live in grasslands and agricultural areas. They’re most common in the northern part of the state. They eat grasses and grains, including wheat and barley.
These grasshoppers can be destructive. In outbreak years, they damage crops and pastures.
Desert And Arid Region Grasshoppers
California’s deserts have their own unique grasshopper species. These insects are adapted to hot, dry conditions.
Desert Grasshopper
This species is well-suited to the Mojave and Sonoran deserts. They’re medium-sized, about 1 to 1.25 inches long. Their color is usually gray or brown, which helps them blend with desert soil.
Desert grasshoppers eat a variety of desert plants, including creosote bush and mesquite. They’re active during the cooler parts of the day. In extreme heat, they hide under rocks or in burrows.
You’ll see them from spring through early fall. They’re most common after winter rains bring new plant growth.
Pallid-Winged Grasshopper
This grasshopper has pale, almost transparent wings. Their body is light brown or gray. They’re about 1 to 1.5 inches long. You’ll find them in sandy desert areas and dry washes.
Pallid-winged grasshoppers eat desert shrubs and grasses. They’re not considered pests because they rarely occur in large numbers. They’re well-camouflaged against sand and rocks.
These grasshoppers are strong fliers. They often fly short distances when disturbed.
Mormon Cricket
Despite the name, this isn’t a cricket. It’s a shield-backed grasshopper. They’re large, up to 2 inches long. Their color varies from black to brown to green. Males have enlarged hind legs that look like drumsticks.
Mormon crickets live in the Great Basin region, including eastern California. They prefer sagebrush and juniper habitats. They eat a wide range of plants, including crops like alfalfa and wheat.
These insects can form large bands that march across the landscape. They can damage crops and even cause traffic hazards when they cross roads.
Coastal And Mountain Grasshoppers
California’s coast and mountains have cooler, wetter conditions. Grasshoppers here are adapted to these environments.
California Coast Grasshopper
This species is found along the entire coast, from San Diego to the Oregon border. They’re medium-sized, about 1 to 1.25 inches long. Their color is usually green or brown with dark markings.
Coast grasshoppers live in coastal scrub, grasslands, and dunes. They eat a variety of coastal plants, including beach grasses and wildflowers. They’re active year-round in mild coastal areas.
These grasshoppers are less common inland. They prefer the cool, foggy conditions near the ocean.
Sierra Grasshopper
This species lives in the Sierra Nevada mountains. They’re adapted to high elevations and cool temperatures. They’re medium-sized, about 1 to 1.5 inches long. Their color is usually dark brown or black, which helps them absorb heat.
Sierra grasshoppers live in mountain meadows and open forests. They eat grasses and alpine plants. They’re active during the short summer season, from June to September.
These grasshoppers are important food for birds and other wildlife in the mountains.
Spotted Grasshopper
Look for small dark spots on their wings and body. That’s how you identify this species. They’re small, about 0.75 to 1 inch long. Their color is usually brown or gray.
Spotted grasshoppers live in grasslands and open woodlands throughout California. They’re common in the Coast Ranges and Sierra foothills. They eat grasses and forbs.
These grasshoppers are not considered pests. They rarely occur in large enough numbers to cause damage.
Grasshopper Habitats Across California
Different grasshopper species prefer different habitats. Knowing where to look helps you find specific types.
Central Valley
This is prime grasshopper territory. The warm climate and abundant crops provide ideal conditions. You’ll find differential, red-legged, and two-striped grasshoppers here. They’re most common in alfalfa fields, pastures, and weedy areas.
Agricultural areas have the highest grasshopper populations. Farmers often need to manage them to protect crops.
Coastal Regions
The coast has milder temperatures and more moisture. Grasshoppers here include the California coast grasshopper and two-striped grasshopper. They live in coastal scrub, dunes, and grasslands.
You’ll see them near beaches, in coastal parks, and along hiking trails. They’re less common in urban areas.
Deserts
California’s deserts are home to specialized grasshopper species. The desert grasshopper and pallid-winged grasshopper are common. They live in sandy areas, washes, and near desert shrubs.
These grasshoppers are most active in spring and early summer. They become less active during the hottest months.
Mountains
High-elevation areas have their own grasshopper species. The Sierra grasshopper and spotted grasshopper live here. They inhabit meadows, open forests, and alpine areas.
These grasshoppers have a short active season. They emerge in late spring and are gone by early fall.
Grasshopper Life Cycle And Behavior
Understanding grasshopper life cycles helps you predict when you’ll see them.
Egg Stage
Female grasshoppers lay eggs in the soil. They use their ovipositor to deposit egg pods underground. Each pod contains 10 to 100 eggs, depending on the species.
Eggs are laid in late summer or fall. They overwinter in the soil and hatch in spring. Some species lay eggs in summer and hatch the same year.
Nymph Stage
Baby grasshoppers are called nymphs. They look like adults but have no wings. Nymphs go through 5 to 6 molts as they grow. Each molt brings them closer to adulthood.
Nymphs eat the same plants as adults. They’re most active during warm weather. They grow quickly, reaching adulthood in 4 to 6 weeks.
Adult Stage
Adult grasshoppers have fully developed wings. They can fly and reproduce. Adults live for several weeks to a few months, depending on the species and conditions.
Mating occurs in summer. Females lay eggs shortly after mating. Some species produce one generation per year, while others have multiple generations.
Identifying Grasshoppers: Key Features
Here’s what to look for when identifying grasshoppers.
- Size: Measure from head to wing tips. Small species are under 1 inch, large species over 1.5 inches.
- Color: Note the main body color and any markings. Look for stripes, spots, or patterns.
- Legs: Check the color of the hind legs. Some species have red, yellow, or black markings.
- Wings: Look at wing color and pattern. Some have clear wings, others have dark spots or stripes.
- Antennae: Grasshoppers have short antennae, unlike crickets which have long ones.
- Body shape: Some are slender, others are more robust. The pronotum (shield behind the head) can have ridges or bumps.
Grasshoppers Vs. Crickets Vs. Katydids
People often confuse these insects. Here’s how to tell them apart.
| Feature | Grasshopper | Cricket | Katydid |
|---|---|---|---|
| Antennae | Short | Long | Long |
| Body shape | Robust | Slender | Flattened |
| Wings | Short to long | Folded flat | Leaf-like |
| Activity | Daytime | Nighttime | Nighttime |
| Sound | Stridulation | Chirping | Soft clicks |
Grasshopper Management In Gardens And Farms
If grasshoppers become a problem, here are some management strategies.
Prevention
Keep your garden clean. Remove weeds and tall grass where grasshoppers hide. Use row covers on young plants. Plant resistant varieties when possible.
Encourage natural predators. Birds, lizards, and spiders eat grasshoppers. Provide habitat for these animals.
Control Methods
For small infestations, hand-pick grasshoppers and drop them in soapy water. Use a net to catch them. Vacuum them up with a shop vac.
For larger infestations, consider biological controls. Nosema locustae is a natural pathogen that kills grasshoppers. Apply it in spring when nymphs are young.
Chemical insecticides are available but use them sparingly. They can harm beneficial insects. Always follow label instructions.
When To Act
Monitor grasshopper populations in spring. Act when you see more than 5 to 10 grasshoppers per square yard. Early intervention is more effective.
Focus on nymphs. They’re easier to control than adults. Apply controls when nymphs are small, before they develop wings.
Interesting Grasshopper Facts
- Grasshoppers have been around for over 250 million years. They predate dinosaurs.
- Some grasshoppers can jump 20 times their body length. That’s like a human jumping over a building.
- Grasshoppers make sounds by rubbing their hind legs against their wings. This is called stridulation.
- In some cultures, grasshoppers are eaten as food. They’re high in protein and low in fat.
- Grasshoppers are important in ecosystems. They recycle plant matter and provide food for other animals.
