Coelioxys hunteri, male, a bee that is a nest parasite of leaf cutting bees. This is just the specialized and distinctive end of this lovely bee. Jones County Georgia, obtained form the USFS Experiment Station...

I think this was the first confirmed state record (Maryland) for this species (Coelioxys immaculata). It was found in Caroline County in a sandy area. Not clear what it is a nest parasite of (almost certainly a Megachile). Something for someone to do....good amateur project. Picture by Amanda Hong.

Coelioxys....invader of Megachile nests. This female is designed to slice into Meg nests and insert and egg which later will kill the baby leaf cutter and consume the food. This one is from the Southwest, Coelioxys novomexicana. This bee was collected in the California Central Valley in Yolo County for research on small-scale restoration in agricultural areas.

A nest parasite, this time a male. Coelioxys octodentata is a counterpart to the more commonly found C. sayi. I associate this species with drier and perhaps sandier locations, perhaps as the nest parasite of things like Megachile brevis. Note the characteristic teeth sticking out of the rear of this bee.

An invader of other bees nests, this is Coelioxys porterae, found, in this case from Acadia National Park in Maine. I can't recall which species of Megachile (leaf cutting bees) this species parasitizes us but there are plenty of options in the park. This is a male, and as with almost all males it has all kinds of pointy projections on its rear end.

The very small and skinny, beetle hole nesting, Chelostoma philadelphi. A specialist on Philadelphus (mock orange). This species is most commonly seen on the non native European Mock Orange that was widely planted in the olden days.

A new species for Vermont, this invasive bee is a specialist on Campanula flowers, collected by Anna Beauchemin, Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash, F5.0, ISO 100, Shutter Speed 200, link to a .pdf of our set up is located in our profile

Chilimalopsis parvula - according to Laurence Packer (world's expert on the bees of Chile) this is a range extension of this species, mapped specimens seem to indicate that it mostly have been captured well to the north of Santiago and we spent all our time to the South on the expedition. Anders Croft took the pictures.

Manuelia postica - One of the common Chilean species of bees, this one was collected somewhere in southern Chile while on expedition last fall with Laurence Packer. Photograph taken by Anders Croft.

A lovely dark Centris with blue highlights and a cape of white. Eyes like coals. What is it thinking? Collected with Laurence Packer while we toured southern Chile and Patagonia sleeping by the side of the road, in the woods or in pastures. Did anyone care. No. Chile is cool.

Colletes aestivalis. Rare? or Not Rare? This is a Heuchera specialist. Heuchera is planted everywhere, why is the species not seen and seen by some as a potential species of concern. A few things pilgrim.

Chino Farms Maryland....they are restoring their grasslands and open land on what I think is the largest farm in Maryland;and as a bonus they got a specimen of the very rare Colletes brevicornis. Hannah and Ashleigh, new interns from my lab took this picture...good job.

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.
