Lasioglossum parvum...collected in Puerto Rico agricultural areas by Sara Prado

Lasioglossum parvum...collected in Puerto Rico agricultural areas by Sara Prado

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.

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.

One of what seem like one billion different kinds of small shiny slightly metallic Lasioglossum species. This one characterized by very sparse pitting on the top of the thorax and bit more glintyness on the abdomen (yep, not great characters).

Now, this is an interesting bee. Obviously it has occurred in Michigan, and indeed until quite recently that was the only place it was known from and in fact, was known only from one single specimen. However, it was so unique that was described by Ted Mitchell over 50 years ago as a new species.

Wetland Bee. There are many bees in wetlands. Why? Because so many wetland plants have flowers that are designed to lure bees. Why, for example, are water lilies so large and colorful? So they look good in our pretend ponds? Nope. To attract bees out into the pond for a little pollination fun? Yup.

Lasioglossum oblongum. An interesting species that pops up here and there. One of the most interesting places for me has been to see it in large numbers along the edges of salt marshes on the Eastern Shore of Maryland, where few other bees persist. Photograph by Brooke Alexander.

Virginia, Page County

Lasioglossum forbesii - A relatively uncommon sweat bee from near Front Royal, Virginia at the edge of the Blue Ridge Mountains.

Of the many types of shiny little sweat bees, this is a large one, not that anyone would notice. Named after the Gotham of Gotham City this species occurs sparingly often in woodlands in the East

Captured as part of a Global Climate Change investigation in National Park Dune systems, yet another tricky Dialictus is photographed here. As the name suggests it is a lover of salt, in this case, salt marshes.. Photograph taken by Kamren Jefferson, bee captured in Timucuan Ecological & Historic Preserve

One of the most common and plain bees in the East. This is the very small Lasioglossum hitchensi. Its commoness did not prevent it from being undescribed scientifically. In only the last 10 years was it given a name by Jason Gibbs, who extracted it from many confusing and similar look alike species.
