Alaska’s short growing season and cold temperatures limit grasshoppers to a few hardy species. When you think about the types of grasshoppers in Alaska, you might picture swarms of insects like in warmer states, but the reality is much more subtle. Only a handful of species have adapted to survive the harsh Alaskan climate, making them a fascinating subject for nature lovers and gardeners alike.
In this guide, you’ll learn exactly which grasshoppers call Alaska home, how to identify them, and where you might spot them during the brief summer months. Whether you’re a curious hiker or a backyard observer, this information will help you recognize these resilient insects.
Types Of Grasshoppers In Alaska
When we talk about the types of grasshoppers in Alaska, we’re really talking about a small group of specialized insects. Unlike the hundreds of species found in the lower 48 states, Alaska hosts only about 10 to 12 native grasshopper species. These insects have evolved unique strategies to cope with freezing temperatures, limited food sources, and a very short window for reproduction.
Most Alaskan grasshoppers belong to the family Acrididae, which includes the common short-horned grasshoppers. They are generally smaller than their southern relatives, with darker coloration to absorb more heat from the sun. Let’s break down the main species you might encounter.
Migratory Grasshopper
The migratory grasshopper (Melanoplus sanguinipes) is one of the most widespread species in Alaska. You’ll find it in meadows, along roadsides, and even in your garden. It has a brownish or grayish body with dark spots on its wings.
- Size: 20–28 mm long
- Color: Brown to gray with dark mottling
- Habitat: Open fields, disturbed areas, agricultural land
- Behavior: Can form small swarms in warm years
This species is a generalist feeder, meaning it eats a variety of grasses and forbs. In Alaska, it’s most active from late June to August. You might notice it jumping away as you walk through tall grass.
Two-Striped Grasshopper
The two-striped grasshopper (Melanoplus bivittatus) is easy to identify by the two pale stripes running down its back. It’s one of the larger grasshoppers in Alaska, reaching up to 35 mm in length.
- Look for two yellow or cream-colored stripes from head to wing tips
- Check for a greenish or brown body with a yellow underside
- Notice its strong hind legs for powerful jumping
This species prefers moist areas like riverbanks and wet meadows. It’s less common than the migratory grasshopper but still widespread in southern Alaska. If you see a large grasshopper with clear stripes, you’ve likely found this one.
Red-Legged Grasshopper
The red-legged grasshopper (Melanoplus femurrubrum) gets its name from the reddish color on its hind legs. It’s a medium-sized species with a brown or olive body. This grasshopper is common in grassy areas and along forest edges.
You can identify it by its red tibiae (the lower part of the hind leg) and the dark band on its wings. It feeds mainly on grasses but will also eat clover and other broadleaf plants. In Alaska, it’s most abundant in the Interior and Southcentral regions.
Clear-Winged Grasshopper
The clear-winged grasshopper (Camnula pellucida) is a smaller species with transparent wings. It has a brown body with a distinctive yellow or white stripe on its pronotum (the shield-like plate behind the head).
- Size: 15–22 mm
- Color: Brown with a pale stripe
- Wings: Clear, often with a slight smoky tint
- Habitat: Dry, sandy soils, open grasslands
This species is known for its ability to survive in cold climates. It lays its eggs in the soil, where they can withstand freezing temperatures. The nymphs hatch in spring and develop quickly to take advantage of the short summer.
Bruner’s Spur-Throated Grasshopper
Bruner’s spur-throated grasshopper (Melanoplus bruneri) is a less common species found mainly in the Interior and western Alaska. It has a brownish-gray body with dark spots and a distinctive spur on its throat (hence the name).
This grasshopper prefers dry, rocky areas and is often found on hillsides or gravel bars. It’s not as abundant as other species, so spotting one is a treat for insect enthusiasts. Its diet consists mostly of grasses and sedges.
Habitat And Distribution
Grasshoppers in Alaska are not evenly distributed across the state. They are most common in the southern and interior regions, where summers are warmer and longer. The Arctic and far north have very few grasshoppers due to the extreme cold.
Here’s a quick breakdown of where you might find them:
- Southcentral Alaska (Anchorage, Kenai Peninsula): High diversity, with 6–8 species
- Interior Alaska (Fairbanks, Denali): Moderate diversity, 4–6 species
- Southeast Alaska (Juneau, Ketchikan): Lower diversity due to rainforest climate
- Western Alaska (Nome, Bethel): Few species, mostly along river corridors
- Arctic Alaska (Barrow, Prudhoe Bay): Very few, if any, grasshoppers
Grasshoppers thrive in open, sunny areas with plenty of vegetation. You’ll find them in meadows, along roadsides, in agricultural fields, and even in your backyard. They avoid dense forests and wet, boggy areas.
Life Cycle In Alaska
The life cycle of Alaskan grasshoppers is tightly compressed due to the short growing season. Most species have a one-year life cycle, but some may take two years in colder areas.
- Egg stage: Eggs are laid in late summer or fall in the soil. They overwinter and hatch in spring.
- Nymph stage: Nymphs emerge in May or June and go through 5–6 molts. They look like small adults without wings.
- Adult stage: Adults appear in July and August. They mate and lay eggs before dying in early fall.
The entire process takes about 60–80 days. This fast development is key to survival in Alaska’s short summer. Some species can even produce two generations in exceptionally warm years.
Identification Tips
Identifying grasshoppers in Alaska can be tricky because many species look similar. Here are some practical tips to help you tell them apart:
- Check the wings: Look for stripes, spots, or clear patterns. The two-striped grasshopper has obvious stripes, while the clear-winged has transparent wings.
- Look at the legs: Red-legged grasshoppers have reddish hind legs. Other species have brown or yellow legs.
- Examine the pronotum: The plate behind the head can have stripes or ridges. The clear-winged has a pale stripe here.
- Note the size: Larger species like the two-striped are easier to spot. Smaller ones like the clear-winged are more delicate.
- Observe behavior: Migratory grasshoppers are more active and may fly short distances. Others prefer to hop away.
If you’re serious about identification, consider taking a photo and comparing it to field guides. The University of Alaska Fairbanks has online resources for insect identification.
Common Look-Alikes
Some insects look like grasshoppers but are actually different. Katydids and crickets are close relatives, but they have longer antennae and different body shapes. In Alaska, katydids are rare, so you’re most likely seeing a true grasshopper.
Another look-alike is the grasshopper nymph, which lacks wings. Nymphs can be confused with small adults, but they have wing buds instead of full wings. With practice, you’ll learn to tell them apart.
Ecological Role
Grasshoppers play an important role in Alaska’s ecosystems. They are primary consumers, eating plants and converting them into protein. This makes them a key food source for birds, small mammals, and even fish.
- Birds: Sparrows, robins, and grouse eat grasshoppers
- Mammals: Shrews, voles, and foxes prey on them
- Fish: Trout and grayling eat grasshoppers that fall into water
Grasshoppers also help with nutrient cycling. Their droppings fertilize the soil, and their bodies decompose quickly, returning nutrients to the ground. In some areas, they can become pests if populations explode, but this is rare in Alaska.
Impact On Gardens And Crops
In Alaska, grasshoppers rarely cause significant damage to gardens or crops. The cold climate keeps their numbers in check. However, in warm, dry years, you might see some nibbling on your vegetables.
If you want to protect your garden, here are some simple steps:
- Encourage natural predators like birds and spiders
- Use row covers on young plants
- Hand-pick grasshoppers if you see a few
- Avoid using broad-spectrum insecticides, which harm beneficial insects
Most of the time, grasshoppers are harmless and even beneficial. They add to the biodiversity of your garden and provide food for wildlife.
Interesting Facts
Alaskan grasshoppers have some amazing adaptations. Here are a few facts that might surprise you:
- Some species can survive temperatures as low as -40°F by producing antifreeze proteins in their bodies
- Grasshopper eggs can remain dormant for several years if conditions are too cold or dry
- The migratory grasshopper can fly up to 20 miles in a single day
- Alaskan grasshoppers are generally smaller than their southern cousins, which helps them conserve heat
- Some species change color based on temperature, becoming darker in cold weather to absorb more sunlight
These adaptations allow grasshoppers to thrive in one of the most challenging environments on Earth. It’s a testament to the resilience of life in the far north.
How To Observe Grasshoppers
If you want to see grasshoppers in Alaska, the best time is from mid-July to late August. Look for them in sunny, open areas with short vegetation. Early morning is a good time because they are less active and easier to catch.
Here are some tips for observing them:
- Walk slowly through grassy fields and watch for movement
- Listen for the buzzing sound of their wings in flight
- Use a net to catch them gently for a closer look
- Take photos for identification later
- Release them after observing to avoid harming them
Remember that grasshoppers are cold-blooded, so they are most active on warm, sunny days. On cloudy or rainy days, they hide in vegetation and are hard to find.
Tools For Identification
To identify grasshoppers accurately, you might need some tools. A good field guide is essential. The “Grasshoppers of Alaska” guide by the University of Alaska is a great resource. You can also use smartphone apps like iNaturalist to get help from experts.
A magnifying glass or hand lens helps you see small details like leg color and wing patterns. A camera with a macro lens is ideal for taking close-up photos. With these tools, you can become a skilled grasshopper spotter.
Conservation Status
Most grasshopper species in Alaska are not considered threatened or endangered. Their populations fluctuate naturally with weather conditions. However, climate change could affect them in the future.
Warmer temperatures might allow new species to move into Alaska, while existing species could shift their ranges northward. This could disrupt ecosystems and affect food webs. Scientists are monitoring these changes to understand the long-term impacts.
You can help by reporting grasshopper sightings to citizen science projects. Your observations can contribute to research on how these insects are responding to a changing climate.
