Ceratina buscki a very small shiny green species from Panama as collected by Sandra Rehan as part of her studies. Ceratina species are almost always stem nesters in the soft pith of brambles and other small woody plants and can be one of the most common bees in some areas.

Ceratina guarnacciona, female, Dominican Republic March 2012

How could one not love the Genus of Ceratina? Elegant, with just the right combination of extra interesting features to keep the interest up. Note the raised clypeus in this one and the lovely fat hairs along the abdominal sections. From the collections of Sandra Rehan at the University of New Hampshire.

Tiny Ceratina from Panama...in the first picture in this series you will see a rod going into its body to hold it in position for photographing in our mini bee studio. Actually this is not a rod but the very tip of the finest acupuncture pin. Yep, that is a small bee.

A Beautiful Invasive. Ceratina smaragdula, male, captured on Hawaii, Oahu, March 2012. This Asian species, along with others has invaded the Hawaiian islands where it thrives in sea of introduced garden plants found at lower elevations on the islands.

A series of pictures of a male and female species that loves Bellflowers (Campanula). Meaning that the female of this species provisions its nest (note: males never help in all Hymenoptera) with the pollen of this plant.

Am playing around with a 10X rig at home right now and aiming at some common species. Here is a seed pod of lamb's quarters. The round objects may or may not be what they call glandular hairs. This is unclear to me.

Pseudagapostemon citricornis - More Chilean bees from Laurence Packer's expedition to southern Chile. Photographs by Kelly Graninger.

Epiclopis gayi - a cleptoparasitic bee (a.k.a nest parasite or cuckoo bee) of almost certainly Centris bees. Perhaps even of the Centris bee that was posted just prior to this as this bee was also collected in southern Chile on the expedition with Laurence Packer. Photos by Kelly Graniger and Anders Croft.

Most Coelioxys look similar (don't you agree?), dulled gray black, heavily pitted, with strong patterns of popping white hair bands. Ah, but here, we have one arrayed in batmobile colors, glossy, midnight black with reduced pitting and purple/black wings.

Still catching up...Here is the face of the Male of Coelioxys gilensis that was posted a while back. Note the fuzzy hairs on the compound eyes...good signature of the genus.

Coelioxys hunteri, male

Colby Francoeur took this picture of a Coelioxys moesta from Pictured Rocks National Monument in Keweenaw County, Michigan. This bee lays its eggs in the nests of Megachile bees. 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.

Coelioxys moesta, female, rare nest parasite of Megachile bees

East Coast, West Coast, this parasitic species, Coelioxys octodentata occurs throughout the United States, almost completely filling the country with records and stopping at the border for some reason. How closely related are the specimens on the Pacific edge versus the Atlantic? Unknown, but for now they are just one species. Red legs are classic C.

The most common Coelioxys in the East. C. sayi is a nest parasite, slipping into the nests of leaf cutters like Megachile mendica and kin and dropping an egg into the wall of their nests. In the female, like this one, the edge of the clypeus is slightly indented (hard to see). Now you know.
