Early Bloomers: Springtime Pollinators

Mining bees are often the first pollinators to visit California’s spring flowers. Their early emergence makes them critical for the pollination of early-blooming plants.

Andrena: The Common Sight in Urban Gardens

The genus Andrena is particularly common in California’s urban gardens. These bees are unassuming but essential, pollinating plants quietly and efficiently.

The Uncommon Genera: Calliopsis, Panurginus, and Perdita

While Andrena may be common, other genera like Calliopsis, Panurginus, and Perdita are less so. These bees have more specialized roles and are a testament to the incredible diversity of the Andrenidae family.

Halictidae Family: The Sweat Bees

The Halictidae family, commonly known as sweat bees, are attracted to perspiration, which they use as a source of moisture and salt. These bees are often small and can exhibit a metallic sheen.

Attraction to Sweat: Moisture and Salt Seekers

Sweat bees are drawn to humans, landing on skin to lap up the salty moisture. This behavior is not just a quirk; it’s a survival strategy that allows them to thrive in various environments.

Metallic Sheen: The Ultra Green Sweat Bee

The Ultra Green Sweat Bee is a stunning member of the Halictidae family, its metallic green body catching the light as it flits from flower to flower.

Common Genera: Agapostemon, Halictus, and Lasioglossum

Genera such as Agapostemon, Halictus, and Lasioglossum are common in California, each with its own unique characteristics and role in the ecosystem.

Megachilidae Family: Leafcutting and Mason Bees

The Megachilidae family includes bees that are master builders, using leaves and mud to construct their nests. These bees are solitary, with each female creating her own nest to raise her young.

Nesting Architects: Utilizing Environmental Materials

Leafcutting and mason bees are resourceful, using materials they find in their environment to build and partition their nests.

Pollen Transportation: Unique Scopae on the Abdomen

These bees have a unique feature called scopae, specialized hairs on their abdomen that they use to transport pollen. This adaptation is key to their role as pollinators.

Garden Regulars: Anthidium, Ashmeadiella, and Osmia

Genera like Anthidium, Ashmeadiella, and Osmia are often found in gardens, where they pollinate flowers and contribute to the health of the garden ecosystem.
