Calliopsis edwardsii, face, 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. P.S.

Calliopsis nebraskensis, Male, Back, New Haven County, CT

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

Wayyyyyy up in the Andes spitting distance from Argentina, this wee Callonychium chilense was collected on an expedition with Laurence Packer to southern Chile. One of those one way dirt roads that hugs the mountains and gives one opportunity to fall into the valley in a truly spectacular way. Memorable.

Calosoma scrutator, back, AR

Fiery Searcher. Calosoma scrutator hunts caterpillars, is big, fast, and spectacular. Just exactly why it is spectacular is clear, when attached it exudes odor heavy on the bad smells and who would want to eat that. So, if you like to dress up in iridescence of any kinds, then just be sure to bring along some repellent to keep the predators at bay.

I don't run into the Blue Cohosh often, but want to say that it is fly rather than bee pollinated...but could easily be wrong. Certainly a woodland understory plant that blooms after much of the bee activity is done with. Picture and specimen from Helen Lowe Metzman.

A bee of the early morning. Matrinal. Restricted to the southeastern United States deep sand spots where it feeds only in the early morning hours. Very uncommonly recorded now but this one was collected by Sabrie Breland in residual burned longleaf pine lands of Southeastern Georgia.
