Identification

Nomada is a large genus with more than 850 species worldwide, more than 280 species in North America.

Nomad bees are usually black, black and red, or entirely red, with yellow, white, and/or red markings. Many species have red legs. The genus Nomada includes the only bees in North America that are entirely red. They have short, thin, and inconspicuous hairs on the body and no pollen-collecting hairs (scopa) on the hind legs. They look more like wasps than a bees.

The compound eye is not centered over the mandible but is shifted slightly back.

The wings are transparent and smoky. There usually are three submarginal cells, the first (innermost) as long as the second and third combined, the third (outermost) relatively short. The marginal cell is sharply pointed and ends on the outer wing margin. The lobe at the base of the hindwing (jugal lobe) is very small, shorter than the submedian cell, and rounded.

Life Cycle

Like other cuckoo bees (subfamily Nomadinae), nomad bees do not construct nests. They lay their eggs in the nests of ground-nesting bees (cleptoparasitic) usually in the genus Andrena. Each species of nomad bee lays its eggs in the nests of only one other species of bee. One to four eggs are laid in the cell wall of the host nest. The larvae have large, outward-facing, scissor-like mandibles. The first larva to emerge destroys all the other eggs, both those of the host and those of its own siblings. It consumes the pollen provisioned by its host, and emerges as an adult the same time as the host adults emerge.

 
Behavior

They hover close to the ground looking for empty nests to parasitize.

Nomad Bee (A Bee That Looks Like A Wasp) that is quite harmless to us. It is what is called a cleptoparasite in that it lays it's eggs in other Bee's nests and sometimes takes some of the pupae in that nest to eat.
