Minnesota’s mix of prairies, wetlands, and northern forests supports a diverse range of grasshopper life. Understanding the **Types Of Grasshoppers In Minnesota** helps you identify these insects in your backyard or on a hike. This guide covers common species, their habitats, and how to tell them apart.
Grasshoppers are more than just jumpy bugs. They play key roles in the ecosystem as food for birds and other animals. Some species can become pests in gardens or farm fields. Knowing which ones you see can help you manage them better.
Common Types Of Grasshoppers In Minnesota
Minnesota hosts over 100 grasshopper species. Most fall into a few main groups based on where they live and what they eat. Here are the most common ones you will encounter.
Red-Legged Grasshopper
This is one of the most widespread species in the state. You can spot it by its reddish-orange hind legs and brownish body. It prefers open fields and roadsides.
- Size: 1 to 1.5 inches long
- Color: Brown or gray with a pale stripe down the back
- Habitat: Prairies, pastures, and crop edges
- Diet: Grasses and some broadleaf plants
Red-legged grasshoppers are active from June to October. They are not usually a major pest, but large numbers can damage hayfields.
Two-Striped Grasshopper
This species has two distinct light stripes running from the head to the wing tips. It is larger and more robust than the red-legged variety.
- Size: 1.5 to 2 inches long
- Color: Brown or olive with yellow stripes
- Habitat: Moist areas near streams, wetlands, and irrigated fields
- Diet: Grasses and sedges
Two-striped grasshoppers are strong fliers. They can travel long distances to find food. In wet years, their populations can explode and cause crop damage.
Differential Grasshopper
This is one of the largest grasshoppers in Minnesota. It has a distinctive chevron pattern on its hind legs. The body is yellowish or greenish with black markings.
- Size: 1.5 to 2.5 inches long
- Color: Yellow, green, or brown with black chevrons
- Habitat: Gardens, crop fields, and weedy areas
- Diet: A wide range of plants, including vegetables and grains
Differential grasshoppers are considered a serious pest in some areas. They prefer lush vegetation and can strip entire plants quickly.
Clear-Winged Grasshopper
As the name suggests, this species has transparent wings with no dark bands. It is medium-sized and blends well with dry grass.
- Size: 1 to 1.5 inches long
- Color: Tan or brown with a mottled pattern
- Habitat: Dry prairies, sandy soils, and open woodlands
- Diet: Grasses and forbs
Clear-winged grasshoppers are common in the western part of the state. They are less likely to invade gardens than other species.
Carolina Grasshopper
This is a large, heavy-bodied grasshopper with a distinct black band on the hind wing. It is often seen on bare ground or gravel roads.
- Size: 1.5 to 2 inches long
- Color: Gray or brown with a black wing band
- Habitat: Open, sunny areas with sparse vegetation
- Diet: Grasses and weeds
Carolina grasshoppers are strong jumpers but weak fliers. They are more common in southern Minnesota.
Grasshopper Habitats In Minnesota
Different grasshoppers prefer different environments. Knowing where they live helps you predict which species you will see.
Prairies And Grasslands
Native prairies are home to many grasshopper species. These open areas provide plenty of grass for food and sunny spots for basking.
- Common species: Red-legged, clear-winged, and two-striped
- Key features: Tall grasses, wildflowers, and scattered shrubs
- Best time to see: July to September
Prairie grasshoppers are important food for birds like meadowlarks and hawks. They also help recycle nutrients by eating dead plant material.
Wetlands And Stream Banks
Moist habitats attract species that need more water. These areas often have lush vegetation that supports larger grasshoppers.
- Common species: Two-striped and differential
- Key features: Cattails, sedges, and moist soil
- Best time to see: June to August
Wetland grasshoppers can be abundant in years with high rainfall. They may move into nearby crops if their habitat dries up.
Forest Edges And Clearings
Woodland edges offer a mix of sun and shade. Grasshoppers here are less common but still present in open patches.
- Common species: Carolina and clear-winged
- Key features: Leaf litter, low shrubs, and dappled light
- Best time to see: August to October
Forest grasshoppers are often more camouflaged than prairie species. They rely on leaf litter for cover from predators.
Agricultural Fields
Farm fields provide abundant food for grasshoppers. Some species become pests when they feed on crops like corn, soybeans, or alfalfa.
- Common species: Differential, red-legged, and two-striped
- Key features: Dense plant growth, irrigation, and bare soil
- Best time to see: July to September
Grasshopper damage in fields is often spotty. Heavy infestations can reduce yields significantly.
Identifying Grasshoppers By Physical Features
You can tell grasshopper species apart by looking at a few key traits. Use these tips to identify what you find.
Body Shape And Size
Grasshoppers range from tiny 0.5-inch nymphs to large 2.5-inch adults. Body shape can be slender or robust.
- Slender bodies: Red-legged and clear-winged
- Robust bodies: Differential and Carolina
- Medium build: Two-striped
Size alone is not always reliable. Young grasshoppers look different from adults of the same species.
Wing Patterns
Wings are a key identification feature. Look for bands, spots, or clear areas.
- Clear wings: Clear-winged grasshopper
- Black band on hind wing: Carolina grasshopper
- Two light stripes on forewings: Two-striped grasshopper
- Chevron pattern on hind legs: Differential grasshopper
Wing patterns are easiest to see when the insect is at rest or in flight.
Leg Color And Markings
Hind legs often have distinctive colors or patterns. This is a reliable way to separate similar species.
- Reddish hind legs: Red-legged grasshopper
- Black chevrons on hind legs: Differential grasshopper
- Plain tan or brown hind legs: Clear-winged grasshopper
- Yellow stripes on body: Two-striped grasshopper
Leg color can fade in older individuals. Check multiple specimens if possible.
Antennae Length
Grasshoppers have short antennae compared to crickets or katydids. Antennae are usually less than half the body length.
- Short antennae: All common Minnesota grasshoppers
- Longer antennae: Usually indicates a different insect group
Antennae are not very useful for telling species apart. Focus on body color and wing patterns instead.
Grasshopper Life Cycle In Minnesota
Grasshoppers go through simple metamorphosis. They have three stages: egg, nymph, and adult. Understanding this cycle helps with control.
Egg Stage
Female grasshoppers lay eggs in the soil during late summer or fall. The eggs are encased in a protective pod.
- Location: In bare soil, often near plant roots
- Depth: 1 to 2 inches below the surface
- Duration: Overwinter until spring
Egg pods can survive freezing temperatures. They hatch when soil warms up in April or May.
Nymph Stage
Young grasshoppers, called nymphs, look like small adults without wings. They molt several times as they grow.
- Number of molts: 5 to 6 times
- Duration: 4 to 6 weeks
- Appearance: Wing buds appear after the third molt
Nymphs are more vulnerable to predators than adults. They stay close to food sources.
Adult Stage
Adults have fully developed wings and can fly. They mate and lay eggs before dying in fall.
- Lifespan: 2 to 3 months
- Activity: Most active in warm, sunny weather
- Reproduction: Females lay multiple egg pods
Adults are the stage that causes the most damage to plants. They are also the easiest to identify.
Grasshopper Control And Management
If grasshoppers become a problem in your garden or yard, there are several ways to manage them. Start with prevention and move to control if needed.
Prevention Tips
Stop grasshoppers before they become a problem. Simple steps can reduce their numbers.
- Keep your yard free of tall weeds and grass
- Remove debris where eggs can be laid
- Encourage natural predators like birds and spiders
- Plant resistant varieties of vegetables
Prevention works best when done early in the season. Check for nymphs in late spring.
Natural Control Methods
You can use biological controls to reduce grasshopper populations without chemicals.
- Beneficial insects: Tachinid flies and parasitic wasps
- Fungal pathogens: Beauveria bassiana sprays
- Nematodes: Steinernema species for soil treatment
- Birds: Chickens, guinea fowl, and wild birds
Natural controls take time to work. They are best for small infestations.
Chemical Control Options
For severe infestations, insecticides may be necessary. Use them carefully to avoid harming beneficial insects.
- Baits: Carbaryl-based baits for targeted control
- Sprays: Pyrethroid or neem oil sprays
- Timing: Apply when nymphs are small
- Safety: Follow label instructions exactly
Chemical control is most effective in early summer. Late-season sprays may not prevent egg laying.
