Types Of Grasshoppers In Utah
Utah’s diverse landscape, from high deserts to mountain valleys, supports a wide variety of grasshoppers. The state’s climate and plant life create perfect conditions for these insects. Some species are native, while others have been introduced over time. Understanding the main groups helps you identify what you see in your yard or on a hike.
Mormon Cricket (Anabrus Simplex)
Despite its name, the Mormon cricket is not a true cricket or grasshopper. It is a shield-backed katydid. But it acts a lot like a grasshopper. These insects are famous for their massive, marching bands that can cover roads and fields. They are dark brown or black, with a bulky body and short wings that do not let them fly. They can grow up to two inches long.

- Why they matter: Some species are minor pests, while others can be problematic in large numbers.
Band-Winged Grasshoppers (Various Species)
These grasshoppers are known for their colorful hind wings. The wings often have a dark band, which gives them their name. When they fly, you see a flash of yellow, red, or black. They are usually medium-sized and prefer open, sunny areas.

How To Identify Grasshoppers In Utah
Identifying grasshoppers can be tricky because many look similar. But you can use a few key features to tell them apart. Look at the size, color, and markings. Pay attention to the legs and wings. Also, note where you found the insect. Here is a simple step-by-step guide.
- Check the size: Is it small (under 1 inch), medium (1 to 1.5 inches), or large (over 1.5 inches)?
- Look at the color: Is it green, brown, gray, or black? Are there any bright colors on the legs or wings?
- Examine the markings: Are there stripes on the back? Are the legs plain or patterned?
- Look at the wings: Are they clear, banded, or solid? Do they cover the whole body?
- Note the habitat: Did you find it in a garden, a field, or a dry rangeland?
- Compare with photos: Use a field guide or online resource to match your findings.
If you are still unsure, you can take a photo and send it to your local extension office. They can help you identify the species and tell you if it is a pest.
Why Grasshopper Populations Fluctuate
Grasshopper numbers can change a lot from year to year. Some years you see only a few. Other years, they seem to be everywhere. This is normal. Several factors affect their populations.
- Weather: Warm, dry springs help grasshopper eggs hatch and survive. Wet, cold weather can kill young nymphs.
- Food availability: When there is plenty of green plants, grasshoppers thrive. Drought can reduce their numbers.
- Natural enemies: Birds, spiders, lizards, and parasitic flies all eat grasshoppers. When these predators are abundant, grasshopper numbers drop.
- Disease: Fungal and bacterial diseases can kill grasshoppers, especially in damp conditions.
Understanding these factors helps you predict when grasshopper problems might occur. If you have a warm, dry spring, be ready for more grasshoppers in your garden.
Grasshopper Control Methods For Utah Homes And Gardens
If grasshoppers are damaging your plants, you have several options. The best approach depends on the size of the infestation and your personal preferences. Always start with the least harmful method first.
Natural And Non-Chemical Methods
These methods are safe for you, your pets, and the environment. They work best for small to medium infestations.
- Handpicking: In the morning when grasshoppers are slow, you can pick them off plants and drop them into soapy water.
- Floating row covers: Cover your most valuable plants with lightweight fabric. This keeps grasshoppers out.
- Diatomaceous earth: Sprinkle food-grade diatomaceous earth around plants. It cuts the grasshoppers’ bodies and dehydrates them.
- Neem oil: Spray neem oil on plants. It repels grasshoppers and disrupts their feeding.
- Encourage predators: Attract birds, lizards, and spiders to your yard. They will eat grasshoppers for you.
Chemical Control Methods
If natural methods are not enough, you can use insecticides. Always follow the label instructions carefully. Choose products that are safe for your specific plants.
- Insecticidal soaps: These are safe for most plants and kill grasshoppers on contact.
- Carbaryl (Sevin): This is a common insecticide that works well on grasshoppers. Use it sparingly to avoid harming beneficial insects.
- Spinosad: This is a natural insecticide made from soil bacteria. It is effective and has low toxicity to humans.
- Baits: Some baits contain insecticide mixed with bran. Grasshoppers eat the bait and die. This is a targeted method.
Remember, chemical control should be a last resort. Overuse can kill beneficial insects and harm the ecosystem.
Grasshopper Life Cycle In Utah
Understanding the grasshopper life cycle helps you control them at the right time. Most grasshoppers in Utah have a similar life cycle. They go through three stages: egg, nymph, and adult.
- Egg: Female grasshoppers lay eggs in the soil in late summer or fall. The eggs are in a pod-like structure. They stay in the soil all winter.
- Nymph: In spring, the eggs hatch into nymphs. Nymphs look like small adults but have no wings. They molt several times as they grow.
- Adult: After about 5 to 6 weeks, the nymph becomes an adult with fully developed wings. Adults mate and lay eggs, starting the cycle again.
The best time to control grasshoppers is when they are young nymphs. They are smaller and easier to kill. They also have not yet caused much damage. Once they become adults, they are harder to control.
Common Misconceptions About Grasshoppers
There are many myths about grasshoppers. Here are a few common ones and the truth behind them.
- Myth: Grasshoppers only eat grass. Truth: Many grasshoppers eat a wide variety of plants, including vegetables and flowers.
- Myth: All grasshoppers are pests. Truth: Most grasshopper species are harmless and play a role in the ecosystem.
- Myth: Grasshoppers bite humans. Truth: Grasshoppers do not bite people. They might nibble if handled, but it is harmless.
- Myth: Grasshoppers only live for a few weeks. Truth: Adult grasshoppers can live for several months, from spring to fall.
Grasshoppers Vs. Crickets: What Is The Difference?
People often confuse grasshoppers with crickets. They are related, but there are key differences. Here is a quick comparison.
| Feature | Grasshopper | Cricket |
|---|---|---|
| Antennae | Short, thick | Long, thin |
| Body shape | Stout, robust | Slender, flattened |
| Sound | Rub legs against wings | Rub wings together |
| Activity | Daytime | Nighttime |
| Diet | Mostly plants | Omnivorous (plants and insects) |
In Utah, you will mostly encounter grasshoppers during the day. Crickets are more active at night and are often heard chirping.
