Oregon’s diverse landscapes, from coastal dunes to high deserts, host a surprising variety of grasshopper species. Understanding the types of grasshoppers in Oregon can help you identify what’s hopping in your backyard or on a hike. This guide covers the most common species, their habitats, and how to tell them apart.

Grasshoppers are more than just jumpy insects. They play a key role in Oregon’s ecosystems, serving as food for birds and other wildlife. Some species can also become pests in gardens and farms.

Oregon is home to over 100 species of grasshoppers. They range from tiny, colorful nymphs to large, winged adults. Here are the main groups you’ll encounter across the state.

Common Field Grasshopper

This is one of the most widespread species in Oregon. You’ll find it in grasslands, pastures, and along roadsides. It has a brown or gray body with dark spots on its wings.

Size: 1 to 1.5 inches long
Color: Brown, gray, or tan with mottled patterns
Habitat: Open fields, meadows, and disturbed areas
Behavior: Active during the day, especially in warm weather

These grasshoppers are not picky eaters. They feed on a variety of grasses and weeds. In large numbers, they can damage crops like alfalfa and wheat.

Red-Legged Grasshopper

As the name suggests, this species has bright red or orange hind legs. It’s a medium-sized grasshopper common in the Willamette Valley and eastern Oregon. You can spot it by its distinctive leg color and striped body.

Size: 0.8 to 1.2 inches long
Color: Brown or olive with a yellow stripe down the back
Habitat: Grassy areas, crop fields, and gardens
Diet: Grasses, clover, and alfalfa

Red-legged grasshoppers are known for their strong jumping ability. They can leap several feet to escape predators. They are also a favorite food for many birds.

Differential Grasshopper

This is a larger species that can be a serious pest in agricultural areas. It has a distinctive chevron pattern on its hind legs. You’ll find it in the drier parts of Oregon, like the Columbia Basin.

Size: 1.2 to 1.8 inches long
Color: Yellowish-brown with black markings
Habitat: Croplands, pastures, and weedy areas
Diet: Corn, soybeans, and other crops

Differential grasshoppers are strong fliers. They can travel long distances in search of food. They are most active in late summer and early fall.

Two-Striped Grasshopper

This species is easy to identify by the two pale stripes running down its back. It’s common in the high desert regions of eastern Oregon. It prefers dry, open habitats with sparse vegetation.

Size: 1 to 1.5 inches long
Color: Brown or green with yellow stripes
Habitat: Sagebrush, grasslands, and rocky slopes
Diet: Grasses, forbs, and shrubs

Two-striped grasshoppers are more solitary than other species. They don’t form large swarms. They are well adapted to the dry conditions of the Oregon high desert.

Clear-Winged Grasshopper

This species is named for its transparent wings with dark bands. It’s common in the Cascade Range and coastal areas. You’ll see it in meadows and forest clearings.

Size: 0.8 to 1.2 inches long
Color: Brown or gray with a pale belly
Habitat: Mountain meadows, forest edges, and grasslands
Diet: Grasses and low-growing plants

Clear-winged grasshoppers are good fliers. They use their wings to escape predators quickly. They are most active during the warmest part of the day.

Migratory Grasshopper

This species is known for its ability to form large swarms. It’s found in the eastern part of Oregon, especially in the Blue Mountains. It has a slender body and long wings.

Size: 0.8 to 1.2 inches long
Color: Brown, green, or yellow with dark spots
Habitat: Grasslands, crop fields, and rangelands
Diet: Grasses, grains, and other plants

Migratory grasshoppers can be destructive when they swarm. They can strip entire fields of vegetation. Farmers in eastern Oregon monitor them closely during outbreak years.

Spur-Throated Grasshopper

This is a large group of grasshoppers with a distinctive spur on the underside of the thorax. They are common across Oregon. They vary in color from green to brown.

Size: 0.6 to 1.5 inches long
Color: Green, brown, or a mix of both
Habitat: Grasslands, gardens, and open woodlands
Diet: Grasses, leaves, and flowers

Spur-throated grasshoppers are named for a small peg-like structure between their front legs. This feature helps scientists identify them. They are one of the most diverse groups in the state.

Slant-Faced Grasshopper

These grasshoppers have a distinctive slanted face and a narrow body. They are common in the coastal dunes and sandy areas of Oregon. They are well camouflaged against sand and soil.

Size: 0.5 to 1 inch long
Color: Gray, tan, or brown with mottled patterns
Habitat: Sandy beaches, dunes, and dry riverbeds
Diet: Grasses and low plants

Slant-faced grasshoppers are fast runners. They often prefer to run rather than fly. They are well adapted to the shifting sands of coastal habitats.

Lubber Grasshopper

This is a large, heavy-bodied grasshopper found in the southern part of Oregon. It has short wings and cannot fly. It walks slowly and relies on its size for defense.

Size: 1.5 to 2.5 inches long
Color: Black with yellow or orange stripes
Habitat: Grasslands, gardens, and open areas
Diet: Grasses, forbs, and garden plants

Lubber grasshoppers are not common in Oregon. They are more typical of the southwestern United States. However, they can be found in the Rogue Valley and other warm areas.

Grasshopper Habitats Across Oregon

Different species prefer different habitats. Understanding where they live helps you identify them. Here’s a breakdown by region.

Coastal Areas

The coast has sandy dunes and grassy meadows. Slant-faced grasshoppers are common here. You might also see clear-winged grasshoppers in coastal meadows.

Willamette Valley

This fertile valley is home to many species. Red-legged and differential grasshoppers are common. They thrive in the agricultural fields and grasslands.

Cascade Range

Higher elevations have cooler temperatures. Clear-winged and spur-throated grasshoppers are found in mountain meadows. They are active during the short summer season.

Eastern Oregon High Desert

This dry region has sagebrush and sparse grass. Two-striped and migratory grasshoppers are common. They are adapted to the arid conditions.

Columbia Basin

This area has rich agricultural land. Differential and red-legged grasshoppers can be pests here. Farmers often need to manage them.

How To Identify Grasshoppers

Identifying grasshoppers can be fun. Here are some tips to help you.

Look at the size. Measure the length from head to wing tips.
Check the color and patterns. Look for stripes, spots, or leg colors.
Observe the wings. Are they clear, banded, or short?
Note the habitat. Is it sandy, grassy, or rocky?
Watch the behavior. Does it fly, jump, or run?

You can use a field guide or an app to help with identification. Take a photo and compare it to known species. Practice makes perfect.

Grasshopper Life Cycle

Grasshoppers go through simple metamorphosis. They have three stages: egg, nymph, and adult. Understanding their life cycle helps with management.

Eggs: Laid in the soil in late summer or fall. They overwinter and hatch in spring.
Nymphs: Look like small adults without wings. They molt several times as they grow.
Adults: Have fully developed wings and can reproduce. They live for several weeks.

Most grasshoppers have one generation per year. Some species can have two in warm areas. The timing depends on temperature and food availability.

Grasshoppers As Pests

Some grasshoppers can damage crops and gardens. They eat leaves, stems, and flowers. In large numbers, they can cause significant losses.

Common pest species in Oregon include:

Differential grasshopper
Red-legged grasshopper
Migratory grasshopper
Two-striped grasshopper

If you have a grasshopper problem, there are several control methods. You can use physical barriers, like row covers. You can also encourage natural predators, like birds and spiders.

Chemical controls are available but should be used carefully. Always follow label instructions. Consider integrated pest management (IPM) for long-term solutions.

Beneficial Grasshoppers

Not all grasshoppers are pests. Many play important roles in the ecosystem. They are a food source for birds, reptiles, and small mammals.

Grasshoppers also help with nutrient cycling. They break down plant material and return nutrients to the soil. Their droppings fertilize the ground.

Some species are indicators of ecosystem health. A diverse grasshopper population suggests a healthy environment. They are part of the natural balance.

Grasshopper Predators

Grasshoppers have many natural enemies. These predators help keep populations in check. Here are some common ones.

Birds: Meadowlarks, hawks, and chickens eat grasshoppers.
Reptiles: Lizards and snakes prey on them.
Insects: Robber flies, mantises, and spiders catch them.
Mammals: Skunks, raccoons, and foxes eat them.

Encouraging these predators can help control grasshopper numbers. Provide habitat like shrubs and rocks. Avoid using broad-spectrum pesticides that kill beneficial insects.

Grasshopper Watching Tips

Watching grasshoppers can be a fun outdoor activity. Here are some tips to get started.

Go out on warm, sunny days. Grasshoppers are most active then.
Walk slowly and quietly. Sudden movements scare them away.
Look in grassy areas, meadows, and field edges.
Use a net to catch them gently. Release them after observation.
Take notes on size, color, and behavior.

You can also photograph them for later identification. Share your findings with local naturalist groups. It’s a great way to learn more.

Grasshopper Conservation

Some grasshopper species are rare or declining. Habitat loss is a major threat. Preserving natural areas helps protect them.

You can help by planting native grasses and flowers. Avoid overgrazing and excessive mowing. Reduce pesticide use in your garden.

If you find a rare species, report it to the Oregon Department of Agriculture. They track grasshopper populations. Your observation can help with conservation efforts.

Common Misconceptions

There are many myths about grasshoppers. Here are a few facts to set the record straight.

Myth: All grasshoppers are pests. Fact: Most species are harmless and beneficial.
Myth: Grasshoppers only eat crops. Fact: They eat a variety of plants, including weeds.
Myth: Grasshoppers can bite humans. Fact: They have strong jaws but rarely bite people.
Myth: Grasshoppers are locusts. Fact: Locusts are a specific type of grasshopper that swarms.

Understanding these facts helps you appreciate grasshoppers more. They are fascinating creatures with unique adaptations.

Grasshoppers And Climate Change

Climate change may affect grasshopper populations. Warmer temperatures can speed up their life cycle. This could lead to more generations per year.

Drought conditions can also impact them. Some species thrive in dry conditions. Others may decline if their habitat changes.

Researchers are studying these effects. They monitor grasshopper populations across Oregon. This data helps predict future trends.

How To Photograph Grasshoppers

Taking good photos of grasshoppers requires patience. Here are some tips.

Use a macro lens or close-up setting.
Get down to their level. Crouch or lie on the ground.
Use natural light. Early morning or late afternoon is best.
Move slowly and avoid shadows.
Take multiple shots from different angles.

Practice makes perfect. Don’t get discouraged if they jump away. Try again later.

Grasshoppers In Oregon Culture

Grasshoppers appear in local folklore and art. Native American tribes used them as food and medicine. They are also a symbol of summer and abundance.

Today, grasshoppers are a part of Oregon’s natural heritage. They are studied by scientists and enjoyed by nature lovers. They remind us of the diversity of life in our state.
