The agapostemon bee is part of the family Halictidae, and is therefore a type of sweat bee.

Native to North America, this medium sized bee is a beautiful metallic green with a yellow and black striped abdomen. Some females are entirely green, or greenish blue.

Female bees also have pollen-collecting hairs, called scopa, on their hind legs, making them effective pollinators. These bees have short tongues and also tend to visit a wide variety of flower species on a single foraging trip to fulfill their diet of nectar and pollen.

Female agapostemon bees often fly fairly fast. Male bees tend to fly much slower because they search the flowers for females to mate with.

Like other sweat bees, agapostemon bees make their nests in the ground. Being solitary bees, each female will makes its own single nest in which to lay its eggs. Sometimes several nests will be located close together, but are still separate. The eggs are each laid in single cells with food provisions for the resulting larvae.
