Wow, check out the expanded basal segments of this male Hylaeus basalis. Probably as big as they get in perhaps any bee in the world. Other Hylaeus have expanded segments (sexual selection?) but not like this. This bee is form Isle Royale a very large island in Superior with all sorts of interesting bees.

Now this is one handsome male. This is Megachile albitarsis, we took it long enough ago (am working through out backlog of things needing photoshopping) that I can't recall the circumstances. This large, not uncommon, southern bee has big hands. These are used to cover the female's eyes during mating. You can make up your own story as to why.

Carrying on from the recent posts of Lithurgus chrysurus, here is another European bee that specializes on Knapweed. This specimen from the West Coast, but it occurs throughout North America. Photo by Anders Croft. This bee was collected in the California Central Valley in Yolo County for research on small-scale restoration in agricultural areas.

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.
