Agapostemon Sweat Bees seem drawn to perspiration, flying around and landing on sweaty arms and legs of unsuspecting people.
There are over a dozen species of Agapostemon Sweat Bees. Males are easier to identity than females because of their distinct coloring. The head and thorax of males are a metallic green, but its abdomen is comprised of the black and yellow bands typically seen in the bee family. Females of many species are mostly green all over. Some species are very social and share nests, while others are more solitary in nature.
Nests are burrows dug into dirt or banks. Pollen grains are collected and placed in each egg's cell to provide food for the expected larva. For this reason, most sightings of adults occur around in or in gardens and meadows laden with blooms. Spring and summer are peak times of year for activity.
Adults drink flower nectar and eat pollen, and are not aggressive. They will sting in self-defense, however, if they are hit or almost crushed. Agapostemon Sweat Bees sometimes get close to, or touch parts of, the body that are perspiring. They seem to enjoy drinking the salty liquid off of our skin. Some are so small and lightweight, they are able to do so without the person even realizing it!
