Colletes pahceliae - As you might suspect it is a lover of the plant phaceliae. Many of the Colletes are tight plant specialists. Only feeding their babies the pollen from one group of plants. With that lifestyle comes your status becomes linked to the the status of those plants. The status of those native plants are a mirror of how we treat our environments.

I stopped by a pullout in the sandhills of Nebraska on my way to the Badlands one year and just did some collecting off the sweet clover and other mostly weedy plants that lined the dirt parking area and along the nearby rail road tracks....fantastically abundant with bees. This was one of them the relatively common Colletes robertsonii. Photo by Erick Hernandez.

A little series of pictures of Colletes robertsonii from the Sandhills of Nebraska...Hooker county. A Midwestern species, this male and female were found in a nice patch of flowers along the road in a small pull off. Lovely country...the Sandhills. Photos by Erick Hernandez.

Not a great specimen, but then again, the species is one we have seen only a few times... you get what you can take. As the name implies there MIGHT be a relationship between this species and golden rod. Is that true? Someone needs to look at little more deeply and perhaps look at the pollen on the bodies of these bees to make such declarations.

Coelioxys hunteri, male, Jones County Georgia

This bee, Coelioxys immaculata, is an uncommon nest parasite of other bees. Almost by definition it must be less common since the young C. immaculata usurps a cell of a leaf-cutter bee, kills the host baby bee and eats its food before emerging the next year. Note the interesting pattern of lobes on its tail end. Mysterious.

Coelioxys moesta, female

Coelioxys moesta, male, Maryland, Garrett County, Collected by Department of Agriculture

Super rare. Only a few individuals of this species have been found, but, interestingly, this species has been found twice in Missouri, and once in Pennsylvania, New Jersey, and Florida. This one was sent to me by Mike Arduser and collected in Clark County, Missouri. Note the lovely flair of hairs around the end of the abdomen....very distinctive.

Another Coelioxys nest parasite bee from the Adirondack Mountains of New York. This one is a nest parasite of big Leaf Cutters like Megachile latimanus. Here are shots of a male and a female.

The most common Coelioxys in the East. This is C. sayi. Now, C. sayi is a nest parasite (like all Coelioxys) and it likes to drop its eggs in the nest of what is usually the most common Leaf Cutter in the East Megachile mendica.

Colletes cariniger: one of the larger early spring species and also one of the more common species in its genus in Greece. The females seen commonly foraging for pollen in fields full of composites like chamomile, mayweed and ragwort. This one was collected by Jelle Devalez on the Aegean Islands.

Colletes compactus is a late fall Colletes, specializing on things like goldenrod. Colletes is an interesting group....different species coming out throughout the year and many of them highly specialized in what they gather pollen from. They perhaps are all specialists, but some are quite rare and so we know little (a common story).

Another mid-summer Colletes from the central prairies. Note the "cute" face with the inner edges of the eyes converging towards the mouth. For some reason this automatically makes a bee cute compared to the standard bee face format that most species display.
