Green Sweat Bee

Florida is home to many bees in this diverse group (60+ species). They range in size, color and behavior. The metallic green sweat bees (Augochlorella, Augochloropsis, Augochlora, and Agapostemon spp.) stand out the most with their flashy green bodies dazzling you as they dance from flower to flower. These are the easiest to pick out in this group and some of them are very common in natural and urbanized areas. The colors among these bees can vary slightly from bright green, to a brassy yellow and even bright blue in some areas! Most of the metallic green sweat bees can be seen almost the whole year as well, starting in February and March and going until November and even December in some areas if it stays warm enough.
