Caenohalictus species, f, right, Near Eric Hampsteads, Chile

More from last year's expedition to Chile with Laurence Packer. Such a lovely country...we camped in a new place every day. Ping ponging from the Andes to the Coast sleeping along the road or in open pastures. Lovely people, easy travel, no problems with law enforcement people. This is a Caenohalictus species of some kind.

As the name implies this species from East of the Andes superficially resembles the parasitic bee genus Nomada. However for whatever reason they have chosen from the wardrobe of bee colors the same cloths they act quite differently. Of note is that both the males and females of this species gather oil in addition to the usual pollen and nectar.

One of the most common bees in Eastern North America, particularly in urban and disturbed environments. They are attracted to piles of dirt or open scraped soils and appear to be a huge fan of clovers, plants that also favor lawns and open disturbed sites.

Calliopsis edwardsii, back, Broward co, Florida

A little, somewhat flattened bee, from the mountains of Yosemite National Park. Members of this group are often very discriminating in their tastes for pollen. Feeding their young pollen often from a single genus of plants. Picky eaters I suppose. Part of a study by Claire Kremen in the high conifer regions of the Park. Photo by Anders Croft.

Now this is a rare bee, I have never seen or collected this species before seeing this lovely male in Kassie Urban-Mead's collection of bees from Connecticut, she collected it last year in a field on Verbena, there are only a scattering of records from NJ to Connecticut representing a disjunct population from the populations occurring in the western prairies, perhap

Perhaps it is too late at night or that I am listening to Enyaesque music and nibbling on pure cacao, but I am transfixed by this particular bee and shot, it just calls up something ancient, something that really brings home the fact that our evolutionary paths separated long ago.

Calliopsis. Another of the many kinds of small bees that run the world. This is one was collected in Arizona by Tim McMahon or Don Harvey in fabulous Cochise County.
