Hoplitis truncata, m, left side, Prince George's Co., MD

Hoplitis truncata. An uncommon Hoplitis that shows up here and there, but never in large numbers. Not well known and its roll and preferences in the world of flowers is also unclear. This is a rather ratty male I collected somewhere near home...will have to keep my eyes open for additional specimens.

Dark Bee. Some bees are all black, black hairs, black integument (skin), little reflection. This makes for somewhat eerie photography, a gothic presentation of a species that does not care what we think. Northern and mountain in distribution across both sides of the continent. This one from way up in Yosemite National Park in California.

The male of Hoplitis albifrons, a common northern and western mountain species. Relatively large, almost the size of a honey bee at least in length. Found in Yosemite National park and collected for a project done by Lauren Ponisio examining the effect of fire diversity on bees (Ponisio et al. Gloebal Change Biol. 2016). Photograph by Samia Shell.

A bee with a fat leg, or at least a wide one. Which is the most distinguising feature of this bee that sadly looks like a whole bunch of other Lasioglossum species. The name? = ...Lasioglossum callidum. i Photograph by Brooke Alexander.

Lasioglossum coeruleum, F, Back, MD, Talbot County

Such a lovely blue and relatively unusual in the Genus Lasioglossum. At least in the East there is no other Lasioglossum so extensively and uniformly blue. So blue that it is often mistaken for an Osmia. This species is associated with woodlands, feeding on the vernal flora of the woods and nearby fields and nesting in rotten wood.

Brianne Du Clos, collected this common Lasioglossum in Maine...probably in or near a blueberry field. Unlike most of our specimens you can see the pollen all over this specimen. Photograph by Dejen Mengis.

Lasioglossum egregium, nicely patterned bands of hair on its hinders, this is a common bee in the West. This particular one is from Bryce Canyon National Park. More to see in Bryce than a bunch of rocks, I think. Photograph by Brooke Alexander.

Well, someone has to take pictures of all these small metallic Lasioglossums. This is L. flaveriae. A Deep South species. I associate it with southern, piney flatlands, but it is based on partial understandings. Bees are so tiny and we look under Mother Nature's hood in so few places.
