Wyoming’s high plains host bumblebees and mining bees adapted to cold temperatures and short summers. When you think about the different types of bees in Wyoming, you might picture just honeybees, but the state is actually home to hundreds of native species. These bees are crucial for pollinating wildflowers, crops, and garden plants across the Cowboy State.
Many people don’t realize that Wyoming’s bees are specially adapted to survive harsh winters and high altitudes. Some species spend most of the year underground, emerging only for a few weeks to feed and reproduce. Others have thick fur coats that help them stay warm even when snow is still on the ground.
In this guide, you’ll learn about the most common bee species found in Wyoming. We’ll cover where they live, what they look like, and how you can help protect them. By the end, you’ll be able to identify these important pollinators in your own backyard.
Different Types Of Bees In Wyoming
Wyoming’s bee population is diverse, with over 600 species documented across the state. These bees range from tiny sweat bees no bigger than a grain of rice to large bumblebees that buzz loudly as they fly. Each species plays a unique role in the ecosystem, pollinating different plants at different times of the year.
The state’s bee communities vary by region. In the mountains, you’ll find cold-tolerant species that can handle freezing temperatures. On the plains, bees that prefer dry, open habitats are more common. Urban areas attract generalist species that can thrive around human activity.
Bumblebees (Bombus Species)
Bumblebees are among the most recognizable bees in Wyoming. These large, fuzzy insects are excellent pollinators because they can fly in cooler temperatures than many other bees. They are also able to perform “buzz pollination,” which is necessary for plants like tomatoes and blueberries.
- Western bumblebee (Bombus occidentalis) – once common, now declining
- Hunt’s bumblebee (Bombus huntii) – found in meadows and gardens
- Nevada bumblebee (Bombus nevadensis) – prefers high-elevation areas
- Yellow-faced bumblebee (Bombus vosnesenskii) – common in urban settings
Bumblebees live in small colonies, usually underground in abandoned rodent burrows. Unlike honeybees, only the queen survives the winter. She emerges in spring to start a new colony, which grows through the summer and dies off in fall.
Mining Bees (Andrena Species)
Mining bees are solitary bees that nest in the ground. They are among the first bees to appear in spring, often emerging while snow is still melting. These bees are important pollinators for early-blooming plants like willows and dandelions.
There are over 100 species of mining bees in Wyoming. Most are small to medium-sized, with dark bodies and light-colored hair bands on their abdomens. Females dig tunnels in bare soil, creating small mounds at the entrance. They stock each tunnel with pollen and nectar for their larvae.
Sweat Bees (Halictidae Family)
Sweat bees get their name because they are attracted to human sweat, which provides them with salt and moisture. These bees are usually small and metallic-colored, often green or blue. They are common in gardens and parks across Wyoming.
Some sweat bees are solitary, while others form simple social groups. They are generalist pollinators, visiting many different types of flowers. Sweat bees are also important for pollinating crops like alfalfa and sunflowers.
Leafcutter Bees (Megachile Species)
Leafcutter bees are named for their habit of cutting circular pieces from leaves to build their nests. These bees are medium-sized and have a distinctive way of carrying pollen on their belly instead of their legs. They are excellent pollinators for gardens and farms.
In Wyoming, leafcutter bees are active from late spring through summer. They nest in pre-existing cavities like hollow stems or holes in wood. You might see them in your garden, cutting neat circles from rose or lilac leaves.
Mason Bees (Osmia Species)
Mason bees are solitary bees that use mud to build their nests. They are early spring pollinators, often active before bumblebees and honeybees. These bees are very efficient at pollinating fruit trees, making them valuable for orchards.
The blue orchard mason bee is one of the most common species in Wyoming. It has a metallic blue-black body and is about the size of a honeybee. Mason bees nest in small holes, which you can provide by putting up a bee house.
Carpenter Bees (Xylocopa Species)
Carpenter bees are large, black bees that resemble bumblebees but have a shiny, hairless abdomen. They get their name from their habit of boring into wood to create nests. In Wyoming, they are most common in the southern part of the state.
Male carpenter bees are territorial and may hover near people, but they cannot sting. Females can sting but rarely do unless provoked. These bees are important pollinators for large flowers like trumpet vine and wisteria.
Long-Horned Bees (Eucera And Melissodes Species)
Long-horned bees are named for the long antennae on males. These bees are medium to large and are often covered in dense hair. They are specialist pollinators for certain plants, like sunflowers and asters.
In Wyoming, long-horned bees are most active in late summer. They nest in the ground, often in large aggregations. You can spot them by their fast, darting flight as they move between flowers.
Plasterer Bees (Colletes Species)
Plasterer bees are named for their habit of lining their nests with a cellophane-like secretion. These bees are medium-sized and have a distinctive heart-shaped face. They are common in sandy areas across Wyoming.
Plasterer bees are important pollinators for plants in the aster family. They are solitary but often nest in large groups, creating a honeycomb-like pattern in the soil. They are active in late summer and early fall.
Yellow-Faced Bees (Hylaeus Species)
Yellow-faced bees are small, wasp-like bees with yellow markings on their faces. They are unique among bees because they carry pollen in their crop instead of on their body. This makes them less effective as pollinators for some plants.
In Wyoming, yellow-faced bees are found in a variety of habitats, from forests to deserts. They nest in hollow stems or small cavities. They are active from spring through fall, visiting many different flowers.
Where To Find Different Bees In Wyoming
Different bee species prefer different habitats. Knowing where to look can help you spot more bees in the wild. Here are some common habitats and the bees you might find there.
Mountain Meadows And Alpine Zones
In the mountains, you’ll find cold-adapted species like bumblebees and mining bees. These areas have short growing seasons, so bees must be active quickly when snow melts. Look for bees on wildflowers like lupine, Indian paintbrush, and mountain daisies.
- Bumblebees are common above treeline
- Mining bees appear early in spring
- Sweat bees are active on warm days
Prairies And Grasslands
Wyoming’s prairies are home to many ground-nesting bees. These open areas provide plenty of bare soil for nesting and abundant wildflowers for food. Look for bees on sunflowers, coneflowers, and goldenrod.
- Long-horned bees visit sunflowers
- Plasterer bees nest in sandy soil
- Leafcutter bees use prairie plants for nesting material
Gardens And Urban Areas
Your garden can attract many bee species. Plant a variety of flowers that bloom from spring through fall to provide continuous food. Avoid using pesticides, which can harm bees.
- Bumblebees visit tomatoes and peppers
- Mason bees pollinate fruit trees
- Sweat bees are attracted to moist soil
How To Identify Bees In Wyoming
Identifying bees can be tricky because many species look similar. Here are some tips to help you tell them apart.
- Look at size – bumblebees are large, sweat bees are tiny
- Check body hair – fuzzy bees are usually bumblebees or mining bees
- Observe behavior – ground nesting vs. cavity nesting
- Note the time of year – some bees are only active in spring
- Use a field guide or app for help
Remember that not all flying insects are bees. Wasps and flies can look similar but have different behaviors. Bees are generally hairy and feed on pollen and nectar, while wasps are smooth and often predatory.
Why Bees Are Important In Wyoming
Bees are essential for pollinating many of the plants that Wyoming’s wildlife depends on. Without bees, many wildflowers would not produce seeds, and the ecosystem would suffer. Bees also pollinate crops like alfalfa, which is a major agricultural product in the state.
In addition to their ecological role, bees support Wyoming’s economy. Pollinators contribute millions of dollars to the state’s agriculture each year. They also support tourism by maintaining beautiful wildflower displays in national parks and forests.
Threats To Wyoming’s Bees
Wyoming’s bees face several threats, including habitat loss, pesticide use, and climate change. Development and agriculture can destroy nesting sites and reduce food sources. Pesticides, especially neonicotinoids, can kill bees directly or harm their ability to forage and reproduce.
Climate change is also affecting bees by altering the timing of flower blooms. If bees emerge before flowers are available, they may starve. Warmer temperatures can also allow pests and diseases to spread more easily.
How To Help Bees In Wyoming
You can take simple steps to support bees in your area. Here are some practical actions you can take.
- Plant native flowers that bloom at different times
- Provide nesting sites like bare soil or bee houses
- Avoid using pesticides, especially during bloom
- Leave some areas of your yard wild
- Support local beekeepers and conservation groups
Even small changes can make a big difference. By creating bee-friendly habitats, you can help ensure that Wyoming’s bees continue to thrive for years to come.
Common Bee Look-Alikes In Wyoming
Some insects are often mistaken for bees. Knowing the difference can help you identify true bees and avoid unnecessary fear.
Hover Flies
Hover flies look like small bees or wasps but are actually flies. They have only one pair of wings (bees have two) and large eyes. Hover flies are harmless and are important pollinators themselves.
Yellow Jackets
Yellow jackets are wasps, not bees. They have smooth bodies and are more aggressive than bees. Yellow jackets are predators that feed on other insects, not pollinators.
Bee Flies
Bee flies are fuzzy flies that mimic bees. They have long, thin legs and a proboscis for feeding on nectar. Bee flies are harmless and are often seen hovering near flowers.
