APPEARANCE

Physical Appearance

Color is dark or grayish brown to black, with bands of pale hair on the abdomen.

 

The female carries pollen in a brush of specialized hairs, called a scopa, on each hind leg.

 

Characteristics

The common name of sweat bee derives from their attraction to human perspiration, which they drink for its salt content.

 

Females of all Halictus species mate before hibernating for the winter, emerging in spring ready to found new nests of offspring. There may be multiple generations of offspring throughout the spring and summer season.

 

True generalists, Halictus species visit a wide variety of flowers for pollen and nectar, and, given the opportunity, are significant pollinators of many crop plants.
