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.

I like looking at this shot, the symmetry, this alien being, this unknowable insect, there is something alive, even relatable here. This one is worth looking at full-screen. What if, indeed, this Megachile brevis, was as large as a puppy dog, would we treat it the same as we do now?

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.

Not originating from here. This is Megachile centuncularis, from studies by MaLisa Spring in Cleveland. Cleveland and other large cities house more than their share of non-native species largely or likely because of the presence of so many non-native weeds and garden introductions.

A Megachile from Morocco that is in the Chalicodoma subgenus, group, or sometimes full blown genus depending upon your taxonomic proclivities. Characteristically the females do not cut leaves to line the nests but use resin or mud and thus do not have the scissors-like cutting edges on their mandibles. This nicely arrayed species is from Iran.

From Bryce Canyon National Park comes a small Lasioglossum, similar to many other species of this specious genus. Western in distribution I know actually nothing about its life. Picture by Brooke Alexander.

A very southern Lasioglossum, this one sneaking up the coast only about as far as this site on Cumberland Island National Seashore.

Another one of those metallic Lasioglossums in the Dialictus group....so similar until you look at them under the microscope ...where they continue to look so similar. It is a world of nuance to us, but somehow many Lasioglossum species evolve, do different things, partition the sexual universe and become species.

Check out the large ocelli on this bad boy. This is Lasioglossum texanum, a dusk loving bee that is out late when the Oenothera (evening primroses) bloom. This is a male, and was found in South Dakota in Badlands National Park.

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.

One of the common Dialictus group Lasioglossum species, often involved in confusion among several similar species. This one collected by Tim McMahon in Cecil County Maryland
