Hylaeus volatilis - A native species of Hawaiian bee found at mid elevations on East Maui. This species is particularly interesting in that it is a nest parasite of other native Hylaeus species

Always a bit floppy, this is St. Andrew's Cross a small bushy thing with long odd petals.....I will admit to knowing little about the plant. Pictures and plant collection by Helen Lowe Metzman.

Lasioglossum brunneiventre. Small, long head, found in the Mojave National Preserve in studies of sandy areas in National Parks. Photographs by Brooke Alexander.

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.

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.

A very deserty looking bee from the deserts of Bryce Canyon National Park. Lovely patterns. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200.

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.

One of the many tricky to identify Dialictus bee species, this from the lovely Cumberland Island National Seashore, Cumberland Island having many interesting species and worthy of much more exploration. Photo taken by Kamren Jefferson

Lasioglossum forbesii - A relatively uncommon sweat bee from near Front Royal, Virginia at the edge of the Blue Ridge Mountains.

Larrini, Unknown species, Dorchester County, April 2012, MarylandLiris argentatus?

6 views of Lasioglossum species which from the sandy areas of Humboldt County, in Redwoods National Park. An Unknown but interesting species, it will have to wait for someone to come along who knows more that we do. Picture by Amanda Robinson.

Denny Johnson from Eau Claire County in Wisconsin provided this specimen. Another Lasioglossum and one that was until recently cleared up by Jason Gibbs involved in thousands of misidentifications...many by myself.

A tricky to identify small sweat bee. Many are identified and there are decades of incorrect keys, murky specimen selection in collections, and even now that Jason Gibbs has provided good clear descriptions they still are so close to other species that ID is not trivial.

This is one of the common European sweat bees, collected in France by Sarah Kocher. The subject of a number of studies that investigates the relationship between geographic location and this bee's level of eusociality (coloniality).
