7-16mm in length; overall shape similar to a honey bee; gaster conical with pointed apex and a flattened underside; heart-shaped face; slightly flattened body; tongue short, fat and split at tips; eyes angled outward; lacks pygidial plate and tufts of hair.

Identification Tips

Colletes species are similar in size and appearance to honey bees but can be distinguished by their dramatic black and white banding on the abdomen and the shape of the gaster.

Habitat

Ground nesting, primarily in the Northern Hemisphere, in various habitats where they can nest in soil.

Distribution

Much of the world, with the exception of Australasia, Madagascar, and the Oriental Region.

Diet

Nectar and pollen from flowering plants.

Life Cycle

Typically solitary; they nest in the ground, building cells lined with a cellophane-like secretion.

Reproduction
