Michigan’s Great Lakes shorelines and inland agricultural areas host grasshoppers with specific habitat preferences. Understanding the types of grasshoppers in Michigan helps you identify them in your garden or during hikes. This guide covers the most common species you’ll encounter across the state.
Types Of Grasshoppers In Michigan
Michigan has over 100 species of grasshoppers, but only about 20 are common enough to notice. They range from tiny pygmy grasshoppers to large, colorful lubbers. Most are harmless to humans, though some can damage crops.
Grasshoppers belong to the order Orthoptera, which includes crickets and katydids. They have powerful hind legs for jumping and two pairs of wings. Males often sing by rubbing their legs against their wings.
Common Field Grasshopper
The common field grasshopper is one of the most widespread types of grasshoppers in Michigan. You’ll find it in meadows, pastures, and along roadsides. It’s medium-sized, about 1 to 1.5 inches long, with brown or gray coloring that helps it blend in.
These grasshoppers eat grasses and weeds. They are active from late spring through fall. Males produce a soft, buzzing song to attract females.
Red-Legged Grasshopper
Red-legged grasshoppers are easy to spot because of their bright red or orange hind legs. They are common in fields and gardens across Michigan. Adults grow to about 1.5 inches and have brown bodies with dark markings.
These insects prefer open areas with plenty of sunlight. They feed on a variety of plants, including alfalfa and clover. In large numbers, they can become pests.
Two-Striped Grasshopper
Two-striped grasshoppers have two distinct pale stripes running down their backs. They are larger than many other species, reaching up to 2 inches. You’ll see them in grasslands and along forest edges.
These grasshoppers are strong fliers and can travel long distances. They eat grasses and broadleaf plants. Their song is a series of short, buzzing notes.
Carolina Grasshopper
Carolina grasshoppers are large, heavy-bodied insects with gray or brown coloring. They have black wings with yellow edges, visible when they fly. These grasshoppers prefer dry, sandy areas like dunes and gravel pits.
They are not strong fliers but can make short, noisy flights. Their diet includes grasses and weeds. You’ll hear their loud, crackling song on warm summer days.
Differential Grasshopper
Differential grasshoppers are among the largest types of grasshoppers in Michigan. Adults can reach 2 inches or more. They have brown bodies with black markings on their legs.
These grasshoppers thrive in agricultural areas and gardens. They feed on corn, soybeans, and other crops. In some years, their populations explode and cause significant damage.
Clear-Winged Grasshopper
Clear-winged grasshoppers get their name from their transparent wings. They are medium-sized, about 1 to 1.5 inches, with green or brown bodies. You’ll find them in grassy fields and meadows.
These grasshoppers prefer tall grass and avoid bare ground. They eat grass leaves and stems. Their song is a soft, continuous buzz.
Migratory Grasshopper
Migratory grasshoppers are known for their ability to form large swarms. In Michigan, they are more common in the southern part of the state. They are medium-sized with brown bodies and a distinct dark stripe behind each eye.
These insects feed on grasses and crops. When conditions are right, they can migrate long distances. Their populations fluctuate greatly from year to year.
Spotted-Winged Grasshopper
Spotted-winged grasshoppers have dark spots on their wings, making them easy to identify. They are small to medium-sized, about 0.75 to 1 inch long. Their bodies are brown or gray with lighter markings.
These grasshoppers live in dry, open areas like prairies and roadsides. They eat grasses and forbs. Their song is a series of short, sharp clicks.
Pygmy Grasshopper
Pygmy grasshoppers are tiny, usually less than 0.5 inches long. They come in various colors, including brown, green, and gray. You’ll find them in damp areas near water, like marshes and stream banks.
These small grasshoppers feed on algae and moss. They are not strong jumpers and prefer to walk or crawl. Their small size makes them easy to overlook.
Lubber Grasshopper
Lubber grasshoppers are large, slow-moving insects with bright colors. In Michigan, the eastern lubber grasshopper is rare but can be found in the southernmost counties. They have black bodies with yellow or red markings.
These grasshoppers are not strong fliers and rely on their toxic body fluids for protection. They eat a wide range of plants, including garden vegetables. Their bright colors warn predators of their toxicity.
Identifying Grasshoppers In Michigan
To identify the types of grasshoppers in Michigan, look at these key features:
- Size: Measure from head to wing tip. Small species are under 1 inch, large ones over 2 inches.
- Color: Note body and leg colors. Some have stripes, spots, or bright markings.
- Wings: Check for patterns, transparency, or colored edges.
- Antennae: Grasshoppers have short antennae, unlike long-horned grasshoppers.
- Song: Listen for buzzing, clicking, or crackling sounds.
Use a field guide or app to confirm your identification. Take clear photos from multiple angles. Note the habitat where you found the grasshopper.
Where To Find Grasshoppers
Grasshoppers live in almost every habitat in Michigan. You’ll find them in:
- Fields and meadows
- Gardens and farms
- Roadsides and ditches
- Forest edges and clearings
- Sandy dunes and beaches
- Marshes and wetlands
They are most active on warm, sunny days. Look for them on plants, on the ground, or flying short distances. Early morning and late afternoon are good times to spot them.
Grasshopper Life Cycle
Grasshoppers go through incomplete metamorphosis with three stages:
- Egg: Females lay eggs in the soil in late summer or fall. Eggs overwinter and hatch in spring.
- Nymph: Young grasshoppers look like adults but lack wings. They molt several times as they grow.
- Adult: After the final molt, grasshoppers have fully developed wings and can reproduce.
Most Michigan grasshoppers have one generation per year. Some species may have two in warm years. Adults live for several weeks to a few months.
Grasshopper Behavior And Ecology
Grasshoppers play important roles in Michigan ecosystems. They are primary consumers that convert plant material into protein. They also serve as food for birds, mammals, reptiles, and other insects.
Grasshoppers are most active during the day. They bask in the sun to warm their bodies. When threatened, they jump or fly away. Some species use camouflage to hide from predators.
Feeding Habits
Most grasshoppers eat grasses and leaves. Some species prefer specific plants. For example:
- Red-legged grasshoppers like legumes like clover and alfalfa.
- Differential grasshoppers feed on corn, soybeans, and other crops.
- Clear-winged grasshoppers eat mainly grasses.
Grasshoppers can consume large amounts of vegetation. In high densities, they can strip fields of plants. This makes them pests in agricultural areas.
Predators And Defense
Grasshoppers have many natural enemies in Michigan:
- Birds: Robins, blue jays, and sparrows eat grasshoppers.
- Mammals: Skunks, raccoons, and mice prey on them.
- Reptiles: Snakes and turtles eat grasshoppers.
- Insects: Praying mantises, spiders, and robber flies hunt them.
Grasshoppers defend themselves by jumping, flying, or hiding. Some species have bright colors that warn predators of toxins. Others use camouflage to blend in with their surroundings.
Grasshoppers In Gardens And Farms
Some types of grasshoppers in Michigan can become garden pests. They chew holes in leaves and stems. In large numbers, they can destroy plants quickly.
To protect your garden, try these methods:
- Encourage natural predators like birds and spiders.
- Use row covers to protect young plants.
- Apply insecticidal soap or neem oil for small infestations.
- Remove weeds and tall grass where grasshoppers hide.
For severe infestations, consider using chemical pesticides. Follow label instructions carefully. Target early instar nymphs for best results.
Beneficial Grasshoppers
Not all grasshoppers are pests. Some provide benefits to gardens and ecosystems:
- They recycle nutrients by eating dead plant material.
- They aerate soil when laying eggs.
- They serve as food for beneficial insects and wildlife.
- They help control weed populations in some cases.
Most grasshopper species cause little or no damage. Only a few species reach pest levels in Michigan.
Grasshopper Conservation
Some grasshopper species in Michigan are rare or declining. Habitat loss and pesticide use threaten their populations. To help conserve grasshoppers:
- Preserve natural habitats like prairies and wetlands.
- Reduce pesticide use in gardens and farms.
- Plant native grasses and wildflowers.
- Create buffer zones around sensitive areas.
Citizen science projects track grasshopper populations. You can participate by reporting sightings to online databases. This helps researchers understand distribution and trends.
Grasshopper Watching Tips
Observing grasshoppers is a fun outdoor activity. Here are some tips:
- Go out on warm, sunny days when grasshoppers are active.
- Walk slowly and quietly to avoid scaring them.
- Look for movement in grass and on plants.
- Use binoculars to see details without getting too close.
- Take photos for identification later.
Keep a notebook to record your observations. Note the date, location, and species you see. Over time, you’ll learn which types of grasshoppers in Michigan are common in your area.
Common Misconceptions
Many people confuse grasshoppers with other insects. Here are some differences:
- Grasshoppers have short antennae, while katydids have long ones.
- Grasshoppers are active during the day, crickets at night.
- Grasshoppers eat plants, while some crickets eat other insects.
- Grasshoppers lay eggs in soil, while katydids lay eggs on plants.
Another common myth is that all grasshoppers are pests. In reality, most species cause little harm. Only a few species reach outbreak levels.
Grasshopper Sounds
Male grasshoppers produce sounds to attract females. Each species has a unique song. Common sounds include:
- Buzzing: A continuous, low-pitched sound.
- Clicking: Short, sharp notes repeated rapidly.
- Crackling: A loud, popping sound like static.
- Zipping: A high-pitched, whining sound.
You can learn to identify species by their songs. Online recordings help you practice. Listening is a great way to find grasshoppers without seeing them.
Seasonal Activity
Grasshoppers in Michigan are most active from May to October. Here’s what to expect each season:
- Spring: Nymphs hatch from eggs and begin feeding.
- Summer: Adults emerge and become most active.
- Fall: Females lay eggs, and adults die off.
- Winter: Eggs overwinter in the soil.
Warm, dry weather favors grasshopper populations. Cool, wet springs can reduce their numbers. Climate change may affect their distribution and abundance.
