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.

Super cool, Super rare, Super fun. Who would say such a thing about a little brown bee? In this case it is Colletes ciliatus. Here is a bee that was featured in a paper we wrote several years ago as one of the "missing bees" not seen for many years.

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.

A cute male bee.... this is the visual of almost all bees in the genus Colletes. Look at how the inner edges of the eyes come closer towards the mouth. For whatever reason, this cutifies pretty much any bee. Enough of that mushy bee stuff. This is a western prairie bee, one that I found at the eastern edge of its range in Hooker, NE.

Hiding in plain site. Is this Cellophane Bee... Colletes latitarsis is a bee that only feeds its babies pollen from the all american weed. Ground Cherry.... Physalis to you sciencey types. The thing about Physalis is that it is very shy about showing its sexual parts. The flowers dangle underneath its leafy roof and are this side of green for a yellow flower.

The bee genus Colletes...also known as Cellophane Bees because of their habitat of lining their cells with a plastic like substance...is full of relatively uncommon bees that specialist on a the pollen of a small number of plants or groups of plants. This may be the case with C. phaceliae given its name...but I am not clear.

Here are 4 views of Colletes phaceliae. Hannah Sutton took these using 4 different back grounds, just to play with something other than a Black background. With these more complicated backgrounds I have a harder time removing the pin in photoshop....perhaps people can give me some feedback on how to make that more seemless.

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.

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 of the Coelioxys nest parasites in the mid-atlantic region. This is C. sayi, in this case, a male and simply a mating machine, not involved in nest construction. Check out the multi-pointed rear end. I am unaware of what use this is, but most of the Coelioxys males have some variant of this unusual pattern. Photographed by Ashleigh Jaoobs.

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.
