One of the western Nomada bee species, that just barely makes into the East. Unusual in how white some of the markings are on the abdomen. This nest parasite was collected by Elaine Evans in North Dakota.

Nomada articulata - A nest parasite of bright green Agapostemons. Most Nomada are nest parasites of Andrena. Not this species. The male is noted for its antenna mods. There is an odd sharp spine underneath the 3rd elongated flagellar segment. Why? Several other Nomada kin have the same thing, so it must be useful.

A nest parasite of a bee. This species lays its eggs in the nests of Agapostemon bees, where it kills the host larva and then eats the stores placed there by the host female. We all know people like this. Bee was collected in New York City as part of a survey of bees of Gateway National Recreation Area. Photograph by Brooke Alexander.

A nest parasite of bees in the genus Agapostemon...perhaps this one targets Agapostemon splendens...which as the name implies is particularly splendidly arrayed in metallic blues and greens. This bee was captured as part of a survey of bees in Gateway National Recreation Area...which includes much of the harbor area of New York City.

The genus Nomada includes many species with murky taxonomies. The group of species with an extra tooth off the tip (we call them the bidentate group) are particularly tricky with molecular working showing it to be a swarm of many "species". So it goes in insect land.

A moderate sized Nomada, a bee that lays its eggs in the nests of bees in the genus Andrena. This species, at least in the male, has a distinctive antennae. You can see it in at least the picture taken of the bee's side that the underside of the antenna is partially eroded away leaving a hollow on each segment.

Rare Bee Alert. Here is Nomada erigeronis. Handful of records...more Midwest...but here is one from the East. New Jersey, in fact. Relatively big. Similar species nest parasitize Agapostemon, but what's up here. Seems to be active in the May-July area.
