Centris haemorrhoidalis - The red-butted bee of Puerto Rico. Another lovely bee from the tropics, sort of a fancy bumble bee in a way. Collected by queen bee of Puerto Rico, Sara Prado. Pictures by Brooke Alexander.

A small Centris species taken by Sara Prado in Puerto Rico

The tail ends of Centris are often brightly colored...surely there is a function, and a reason, but why does it often appear to us to also be beatutiful?Another Caribbean bee collected from Puerto Rico by Sara Prado. A lovely male. Photographed by Brooke Alexander.

Interesting and very uncommon bee. Meet Coelioxys banksi. I have only seen a couple, both from NJ, I think. What bee is their host? There are specimens from the East Coast and from the West with a hiatus in the middle. Are they different species or are we simply lousy at finding them? What ever is going on , a pretty slick looking bee.

A lovely Coelioxys from Argentina...note the hair emerging from the eyeballs..one of the few groups of bee species to have this characteristic. (honey bees being the most famous hairy eyeball bees). A nest parasite of Megachile, this female is typical in shape of the abdomen, long and sharp designed to insert eggs into the walls of the other bee's nests.

First Maryland state record for this species as represented by this male from Eastern Neck National Wildlife Refuge on a wee island in the Chesapeake Bay. As a Coelioxys it is going to be a nest parasite of Megachile...in this case it is going after Megachile petulans....a species with a more southern distribution.

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.
