Early spring wildflowers, like the Virginia Spring Beauty (Claytonia virginica), are an important source of food for a host of small bees and other insects. Many insects gather pollen from these flowers and in doing so help to pollinate the plants.
Some species of bees, though, lack scopa (the pollen-collecting hairs) and do not collect pollen to feed their offspring. The genus Nomada, according to Wikipedia, is the largest genus of kleptoparasitic bees sometimes referred to as “cuckoo bees.” Kleptoparasitic bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected.
It is a little hard to see the body of the bee in the photo below, but if you look closely you can see its striped abdomen, which is wasp-like in appearance. I was not sure of the type of bee, so I posted it to BugGuide, a useful resource for insect identification, and one of the experts there identified the bee as belonging to the genus Nomada.
