Intersex Bombus bimaculatus, gyn, male side, Washington, OH

As happens rarely in bees, this bee exhibits both characters of males and females, with bilateral asymmetry. Found by MaLisa Spring in Marietta, Ohio as part of her studies of the bees or the region, which in addition to this species discovered several new state records and rare bees.

One of the tricky clade of a small black bees that occur throughout the West. In this case the species of Lasioglossum glabriventre was found at fossil Butte national Monument. You should visit because it is rich in bees and apparently fossils to. Picture taken by Sue Boo.

Lasioglossum gotham is a small sweat bee, that I find mostly in the early spring, mostly in Woodlands and I suspect it is very much keyed in to nesting in upturned root masses of trees in those woodlands.

A common little bee of the Badlands. Lasioglossum incompletum is at the eastern edge of its range here at the Badlands. No one really realizes that the world is dominated by small bees. So much for bumble bees. Picture by Anders Croft.

The male of the female Lithurgopsis gibbosus already presented on this site. An uncommon species compared to its sister genus Megachile, it is often overlooked because of the superficial similarities.

A bee from across the pond. This is Lithurgus chrysurus. This is a Euro bee, but in the 70s some one noticed that their house in Philipsburg, NJ was being drilled to bits by bees.

In North America this genus are primarily cactus pollen specialists. Since this one was captured in the sandhills of North Carolina by Heather Campbell it is undoubtedly covered in Prickly Pear cactus pollen.

Lithurgus tibialis: a fascinating species in that it is much smaller and looks quiet different from other Lithurgus species occurring in Europe and has the peculiar preference for flowers of Chrozophora, a quite unusual pollen source.., but from studies in Greece it is clear that the females almost solely visit this plant and collect its pollen.

Ah, the lovely wild hummingbird attracting Cardinal Flower. Nice to have bright red emerging from the wetlands every once in a while. Photograph and specimen by Helen Lowe Metzman.
