Coelioxys banksi, f, face, Mercer Co., NJ

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.

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.

Roooooarrrrrr!, Danger, creature from the black lagoon. Or...not. Here we have a close up look at the many interesting features that are left behind when a cicada emerges. This one was in my backyard and left his/her full body suit behind on the shed.

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.

More Hylaeus from Panama, this little species was collected by Sandra Rehan, lovely wing pop or wing interference patterns. So glossy you can see the camera lens in the reflections.

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.
