I like this particular view of the underside of this bee. The black hairs are characteristic of the species, but it is also an oddly appealing picture in its aspect and layout, at least to me.Megachile apicalis - Invasive species: Specialist on knapweeds: Not common unless you haunt industrial and other wastelands where it can be common.

A trinomial: Megachile brevis onobrychidis. Thus it is a declaired subspecies of M. brevis of which there have been several and at least one has turned into a species. Since the distribution of M.

Great Smoky Mountains National Park, Tennessee - A leaf cutting bee, common throughout much of North America

From the Adirondacks of New York comes Megachile centuncularis. Sadly, it is an invasive species that can be quite common in northern cities across the U.S. as well as throughout the northern part of the globe. Maybe that is why it is so successful, it likes our holes.

Hawaii was colonized once by a single species of Masked Bee (Hylaeus), and evolved and split into dozens of species. Subsequent to Polynesian and European colonization a steady progression of non-native plants and bees have invaded.

Sara Prado found this Megachile concinna in agriculture fields in her Puerto Rico studies. Is it native to P.R.? Nope. It is a tramp species that shows up in different places from its homeland in the Mediteranean. Photo by Brooke Alexander.

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.

Lasioglossum rozeni, Female, Frederick County, Maryland, Catoctin Mountain Park, a nest parasite of other Lasioglossum species

From Mount Washington in New Hampshire. A new species for New England this species has a boreal distribution and probably is a hold out from colder days, eking out a living in the White Mountains until global climate change turns it into a jungle.

A rather lovely Lasioglossum from Bryce Canyon National Park (L. sisymbrii) als black and white stripes. Common in the West...leaking a bit into the plains, but not much.

Lasioglossum sopinci lives in sand deserts in Eastern North America.

Lasioglossum sopinci, the undescribed male of this sand specialist, found along some lovely powerline...

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

The underside of the head of Lasioglossum heterognathum. An uncommon species that has the feature that can be seen here, which is that the recessed area that holds the folded tongue (the hypostomal cavity) widens out towards the mandibles rather than stays as a parallel sided slot like other Lasioglossum species. Yawn, I know. Photograph by Amanda Robinson.

Catching up...Here is a not that great shot of Lasioglossum inconditum from Fossil Butte National Monument in Wyoming.
