Bumblebees (Bombus)

You know them well: the round fuzzy ones with contrasting colored bands of soft hair (typically yellow and black). Alaska has 22 known species of bumblebees.

Solitary Bees

Solitary bees differ from their larger, more charismatic relative the bumblebee because they do not form hive. As their name suggests, they spend their life cycle in solitude.

Leafcutting bees (Megachilidae)

These solitary bees are named for their tendency to collect leaves to construct their nests. Nest sites include holes in stems or wood, existing cavities in old buildings, or holes in the ground. Like bumblebees, these bees feed on nectar and pollen.

Sweat Bees (Halictidae)

You might encounter a sweat bee on a hot, sunny day when they are attracted to the salts secreted in your sweat. These good, general pollinators are typically black or metallic colored, but some are bright green or dark yellow. They nest in the ground in dispersed solitary nests or densely situated nests with bees sharing a common entrance.

Mining Bees (Andrenidae)

Mining bees are a large family of bees found nearly everywhere in the world. They resemble honeybees — they typically have a dark a dark colored body with fine light brown or yellow hairs. These solitary bees don’t form nests but rather dig a single nest into the soil, hence their name. If you like wild blueberries you can thank mining bees — they’re important blueberry pollinators.

Plaster Bees (Colletidae)

The name of this solitary bee originates from the way that they smooth the walls of their nests with secretion from their mouthparts. These secretions dry into a plaster-like lining. Oftentimes, this variety of bees will not have external ways to carry pollen, so they will carry pollen in their crop (a specialized part of the foregut).

Celebrate and support native bees

All types of bees play an essential role in Alaska’s ecosystems. They ensure healthy and productive plant communities, which lead to healthy mammals and bird populations.
