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.

This is the male of a species that parasitizes Megachile (leaf cutter nests) by laying their eggs in the nest of the host, after which the young Coelioxys sodalis emerges and kills the host larvae and consumes the pollen and nectar of the host's young. About 20% of all bees work on this model.

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.

Back to the Badlands of South Dakota. Here we get Diadasia....something that only shows up once you hit some of the isolated prairies in the MidWest until when you got to much of the West...they are everywhere. A common species, this one was found in a number of locations in the Badlands.

Fuzzy, round-headed, and big are a pretty good short cut to the ID of Diadasia bees. Westerners, they, in a very casual pocket prairie sort of way make East of the Mississippi River. The bulk of the population is in dry natural areas from the middle prairies to the West. Here is a common one from our work in the Badlands of South Dakota.

I think many people think of cacti as icons, something made for us to look at, but since we rarely use cacti for anything and because their fleshy shapes and lifestyles are so different we think of them more as lampposts than integrated into our landscapes as much as the grasses, forbs, and trees. But without cacti entire worlds would disappear.

Collected in Chile in Patagonia near Chile Chico,on an expedition with Laurence Packer. This is a Diadasia of some sort. Laurence, surely will figure out all the species names so we can update these pictures.

Dianthidium curvatum, how cool is this bee? Specimens collected here from Sabrie Breland in Baker County in Georgia, we should all live in such a bee rich location.

An uncommonly collected species whose status is largely unknow because people don't spend enough time swimming in the mud to look at the bees coming to Pickerelweed. There are 3 eastern uncommon species all from different genera who are specialists on this plant...this is one, and was collected in Maine by Samantha Gallagher.
