These small bees have black bodies; the thorax and abdomen have yellowish—white setae.
Nests are usually made in clay soil, and many nests may
occur together. Females excavate a long burrow in the
ground; along the sides of the burrow are short branches
that lead to a brood cell. These cells contain pollen and
nectar and a single egg. Several females may use one
burrow.
Habits. Sweat bees are attracted to perspiring (sweating)
individuals. Although they are non—threatening, they will
sting when there is activity near the nest.
