This Lasioglossum comes from Yellowstone National Park. If we actually had a good shot of its head you would see that it has an interesting and large one, but we don't, so you just have to be satisfied with the top of the abdomen, which is nice enough for a bee.

From the Badlands of South Dakota...Lasioglossum paraforbesii. One of the large northern Lasioglossum species. This one found lurking about some of the prairie habitats in the National Park on our expedition there. Upon close inspection you can see that this bee has one rather than two weakened cross veins in the submarginal cells...but you knew that.

Ah, a dark Lasioglossum, small, all black, a bit of gloss on the thorax, sides rough, angulate, like crumpled tinfoil, except black. Small, common, and expected thoughout the East.

Lovely and subtle wings, patterned in tiny hairs and blinged with iridescenceOne 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.

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.

One of the many small difficult to separate by species Lasioglossums. This one was identified by Jason Gibbs and found in Fossil Butte, Wyoming at the National Monument. Photograph by Brooke Alexander.

A bee of western North America. This one was captured in Bryce Canyon National Park, one of the larger "sensu strictu" group of Lasioglossums.

Here is a bee that clearly loves woodlands: Lasioglossum versans. In the obscure morphological vernacular of tiny sweat bees, I identify it by its tiny bulging purple "nose" (supraclypeus) and its complete lack of a hair fan on the base of T1.

Lasioglossum versatum. One of the most common little sweat bees in the East. Particularly common in the cooler mid-latitudes. These bees can dominate the captures in surveys of bee species of a region. Something of a mess taxonomically.

Sand. The Golden Sand Loving Bee. When I think of bees that are sand loving I think of Lasioglossum vierecki. For one, how nice to have a golden orange bee to look at. For second it is common in sandy areas...so if you are going to find a sand specialist in a sand mine, dune, beach, barren, sandhill in the Northeast there you will find this little orange bee.
