Dark Bee. Some bees are all black, black hairs, black integument (skin), little reflection. This makes for somewhat eerie photography, a gothic presentation of a species that does not care what we think. Northern and mountain in distribution across both sides of the continent. This one from way up in Yosemite National Park in California.

One of many species of slightly metallic Lasioglossum in the Dialictus group. Lasioglossum perpunctatum is a northernly inclined species found in the Appalachians and up across northern North America.

In the Badlands of South Dakota comes a red-butted Lasioglossum. Most have dark posteriors, but not this one, which means that identification is simplified. But, one must still untangle this species from the handful of other species with red on the abdomen. Its still a mystery to me how all these Lasioglossums carve up the floral space.

The little metallic members of Lasioglossum all tend to look alike until you put them under the scope, once you do you see that some of them don't have pollen carrying hairs .... such as this L. platyparium. Those are members of the genus that are cleptoparasitic on other Lasioglossum.

A little parasitic Lasioglossum from Frederick County, Maryland. The female invades nests of other Lasioglossum species and lays her egg in their nest. The host egg/baby does not fair well after that. The most common of the parasitic Lasioglossum species.

Bryce Canyon, little tiny sweat bees, lots of different species. Not what people come to see, but what you now can see here because the National Park Service cares. Photography by Brooke Alexander.

Lasioglossum sequoiae, F, Face, WA, San Juan County

Rare. This small little Lasioglossum sequoiae is all black. This particular specimen was collected in the San Juan Islands of Washington in the National Historic Park and identified by the fabulous Jason Gibbs. This represents a major range extension for all the previous specimens we are aware of are known from California.

We have had pictures of this sand lover before, but just got this one fresh from a study of a local sand mine where with the state mines division they created new bee habitat as a trial and this sand specialist was glad to show up.

Aptly named: Lasioglossum coeruleum. Most of the many confusing members of these small sweat bees glimmer discretely in metallic integument, but our friend here takes it up a notch to and Osmia level.

Such a lovely blue and relatively unusual in the Genus Lasioglossum. At least in the East there is no other Lasioglossum so extensively and uniformly blue. So blue that it is often mistaken for an Osmia. This species is associated with woodlands, feeding on the vernal flora of the woods and nearby fields and nesting in rotten wood.

Lasioglossum egregium, nicely patterned bands of hair on its hinders, this is a common bee in the West. This particular one is from Bryce Canyon National Park. More to see in Bryce than a bunch of rocks, I think. Photograph by Brooke Alexander.
