Ceratina cockerelli, male

null

How could one not love the Genus of Ceratina? Elegant, with just the right combination of extra interesting features to keep the interest up. Note the raised clypeus in this one and the lovely fat hairs along the abdominal sections. From the collections of Sandra Rehan at the University of New Hampshire.

Ah, a mysterious Ceratina introduced into the Hawaiian island chain. This species is found throughout the islands now, but no one is quite sure what the species is. It is near the species C. dentipes but may or may not be it. So many mysteries in the world and too many introduced species. Photography by Sierra Williams and Photoshopping by Elizabeth Garcia.

Tiny Ceratina from Panama...in the first picture in this series you will see a rod going into its body to hold it in position for photographing in our mini bee studio. Actually this is not a rod but the very tip of the finest acupuncture pin. Yep, that is a small bee.

Yep, there are a lot of Ceratinas out there in the world. Here is the last in the series of Ceratinas from Sandra Rehan. As usual it is a small one from Panama. Tiny bees almost always have plenty of wing pop...no exception here.

Yet more Ceratina pictures, diversity demands it. This series is from specimens collected in Panama by Sandra Rehan (UNH) as part of her mission to know everything there is to know about Ceratinas.

Most Coelioxys look similar (don't you agree?), dulled gray black, heavily pitted, with strong patterns of popping white hair bands. Ah, but here, we have one arrayed in batmobile colors, glossy, midnight black with reduced pitting and purple/black wings.

The dark and mysterious nest parasite of Megachile xylocopoides, one of the few records for the state of Maryland, but more are expected as M. xylocopoides spreads northward. This specimen from Eastern Neck National Wildlife Refuge, Kent County.

The taper looks of a nest parasite of Megachile. This is Coelioxys gilensis. Found in Yosemite National park and collected for a project done by Lauren Ponisio examining the effect of fire diversity on bees (Ponisio et al. Global Change Biol. 2016).

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.

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.

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.

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 series of pictures of a male and female species that loves Bellflowers (Campanula). Meaning that the female of this species provisions its nest (note: males never help in all Hymenoptera) with the pollen of this plant.

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

Chiasmognathus c.f. gussakovskii, Cross Mandibled Bee, specimen collected by Wojciech Pulawksi in TajikistanVery small bees have very small nest parasites.
