Here is a little tiny nest parasite, Lasioglossum simplex, that parasitizes one of its sister taxa (likely L. trigeminum). While it retains the overall look and feel of its pollen carrying upright relatives, it has no pollen carrying hairs and its mandibles lack the tooth at the end and instead are simple sabres...

New Hampshire...The White Mountains...Mount Washington....at the very top is tundra a small remnant of what was more extensive in the cold post glacial times and still harbors arctic species like this Lasioglossum boreale. At this point this is the only location that has had this species in New England.

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. Photograph by Brooke Alexander.

The Channel Islands lie off the southern coast of California and contain quite a few endemic plants and animals. Here is a bee species that falls in that category and was collected as part of an effort to survey the climatically vulnerable National Parks. Photography by Ashleigh Jacobs.

Aptly named: Lasioglossum coeruleum. Most of the many confusing members of these small sweat bees glimmer discretely in metallic integument, but our friend here takes it up a notch to and Osmia level.

Here is a bee that clearly loves woodlands: Lasioglossum versans. In the obscure morphological vernacular of tiny sweat bees, I identify it by its tiny bulging purple "nose" (supraclypeus) and its complete lack of a hair fan on the base of T1.

Often the most common Lasioglossum at a location in the East. This is Lasioglossum versatum. While common it has the sad trait of sometimes looking like L. trigeminum or L. callidum or L. adimirandum. In isolation they all seem so separable, but since they often occur at the same site and have a tendency to look slightly similar it can be a nightmare.

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.

From Organ Pipe National Monument comes the small and very common western Lasioglossum microlepoides. Just like the seemingly endless supply of these small Halictid bees, it is slightly metallic and and has a strongly bent basal vein. One could spent a couple lives just figuring out the different species. Photography by Brooke Alexander.
