While there are 26 similar subspecies of Western Honey Bees, these can be identified by orange-yellow rings, black bands, and a hairy thorax.

Bees of the genus grow largest when they’re queens. Western Honey Bee queens grow to 20mm compared to males known as drones who only grow to 17mm. Worker Western Honey Bees grow to a maximum size of 15mm.

These bees are known to live in wetlands and drylands, provisioned there’s sufficient water and food around.

Nesting in cavities, these bees have a major pollination role. They also produce honey.

Honey from these bees is known for being made from the pollen of various flowering plants. It mainly contains fructose and glucose.

2. Western Carpenter

Western Carpenter Bee

Also known as the California Carpenter, the Western Carpenter Bee (Xylocopa californica) is native American.

They are known for their positive pollination role in woodlands and with flowering plants found in deserts.

3. Sonoran Bumble Bee

Sonoran Bumble Bee

Sonoran Bumble Bees (Bombus sonorus) are native to the Sonoran Desert. They are recognized by their large black and yellow bodies.

These bees grow up to 18mm.

Sonoran Bumble Bees look similar to other black and yellow bees but they can be distinguished by flight season.

They are very active in late summer and the fall, unlike most other bumblebees active in spring and summer.

These bees live in nests established by a queen. Both nests and queens survive up to a year.

Unlike other honey-making bees, the Sonoran Bee nest isn’t known for clear cast separation.

Most bees contribute to collecting pollen and to maintaining the nest.

4. Valley Carpenter Bee

Valley Carpenter Bee

Valley Carpenter Bees (Xylocopa sponsoring) are common in Arizona and nearby states. They are known for their all-black body.

These bees have a blackhead, black wings, and black hairy legs.

Valley Carpenter Bees are efficient pollinators with their hairy legs. These bees have been shown to visit up to 16 various flowers per minute with a large pollination role.

It was also the only known Brachymelecta species that is today found all across the US.

12. Barrel Cactus Longhorn

This species (Svastra duplocincta) is common in Arizona, Texas, and Northern Mexico.

These hairy bees are excellent pollinators of Compact Barrel Cactus flowers.

13. Morrison’s Bumble Bee

Morrison’s Bumble Bee

With a diminishing status across states such as California, Morrison’s Bumble Bee (Bombus morrisoni) is still seen in Arizona.

The species is known for nesting in various habitats across the states. Woodlands and dry soils are preferred for building nests.

These bees are known for generally using existing cavities that they further excavate to create underground nests.

Some of these nests are compromised by multiple chambers, used to lay eggs.

These bees are common pollinators of decorative flowers. Preferred visited flowers include wild roses, alfalfa, and goldenrod.

15. Black-tailed Bumble Bee

Black-tailed Bumble Bee

The Black-tailed Bumble Bee (Bombus melanopygus) gets its name from its all-black abdomen contrasted by a golden yellow-brown thorax.

These hairy bees are known as excellent pollinators with very good adaptability skills.

Black-tailed Bumble Bees are found across multiple habitats within Arizona which includes urban environments.

Bees of the species are mainly known for nesting underground but they can find individual shelters even above the ground.

Common benefits of these bees include pollination roles for willows, lilacs, and wild buckwheat.

16. Nevada Bumble Bee

Nevada Bumble Bee

Unlike its name suggests, the Nevada Bumble Bee (Bombus nevadensis) is widespread throughout the US, including Arizona.

Unlike most other bees in the state, Pallid Deser-Digger bees pollinate cacti and other plants of the desert such as desert willow.

The bees have been extensively studied for their communication based on pheromones.

Virgin females release a pheromone that attracts females.

This pheromone is released before females first emerge from an underground nest. This is the reason males are often seen patrolling the areas around these underground nests.

20. Spotted Woolcarder

Spotted Woolcarder

This solitary bee species (Anthidium maculosum) is known for having a wide short body of black and yellow color.
