Metallic Green Bee
Agapostemon. These are true native bees in the family Halictidae (the Sweat Bees). But they are quite different from the familiar – but non-native - European Honey Bees.
Metallic Green Bees are found in North and South America. There are about 40 species, with the greatest abundance in temperate regions and Southwestern United States. The Agapostemon are floral generalists, which means that they visit a number of different flower species. Despite their lack of specificity, generalists like Metallic Green Bees can be important pollinators in gardens and in the wild.
Metallic Green Bees are short-tongued, so they favor flowers with a relatively open architecture and easily accessible nectar, which serves as food for adults. Like all foraging insects, they appreciate the convenience of plants with many small flowers clustered together. This in part explains why you’ll notice Metallic Green Bees visiting plants in the Sunflower family (Asteraceae; including Sweet-scent) and the Buckwheats (genus Eriogonum). Both of these plant groups feature many small simple flowers that produce high-quality nectar.
