There are an estimated 4,000 species of bees native to North American and range in size from carpenter bees, which are over an inch long, to tiny Perdita bees that barely reach 1/16 of an inch. 

Native bees range in color from black or brown with yellow, orange, white, or pearl-colored markings. Others have body parts in metallic green or blue. Some are furry, while others are almost hairless. 

Bees belong to the insect order Hymenoptera, which means “membrane-winged.  These insects possess two pairs of wings, a distinct “waist,” and mouthparts adapted for biting or chewing. Bees are distinguished by their branched body hairs which are helpful in trapping pollen grains, and their wide leg segments.
