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.

A new record for Hawaii for Maui, this introduced species (only some members of Hylaeus are native) was known from other islands but this appears to be the first record for Maui. Not surprising since it nests in wood and could easily be transported among islands or it is big enough that it could simply fly there.

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.
