White Oak Borer (Goes tigrinus) - larvae live in living white and related oaks - , but which one? Where is a Coleopterist when you need one... Collected by Bob Trumbule, fab entomologist for the state of Maryland in our building (likely because there elements of dead wood present).

And now....Ceratina from Asia! Vietnam to be exact. The overall shape and aspect of Ceratinaness remains but what lovely facial colors or maculations as the old literature calls them. A betting person would use the patterns of past specimens to guess that the female will have fewer maculations, but the stripe running down the center of the clypeus will remain.

Tiny, Tiny, Ceratina arizonensis from the Zuma Canyon in the Santa Monica National Recreation Area in coastal California. Almost all Ceratina have that white stripe (or some greater embellishment thereof) on their face and are relatively hairless, perhaps because of their lifestyle in the pith of plant stems or...perhaps not.

A blueberry specialist. Look how long that face is...The space between the mandible and the eye is what bee heads often use to separate species. This Colletes validus has a huggggggeeee malar space...other Colletes species essentially have none, the mandible being directly at the base of the eye. Why?

Look at the veryyyyyyy long distance from the bottom of the compound eye to the mandible base (technically this is called the malar space). Few bees show this long a head and it is nearly distinctive within Colletes at least in the north. This is a species that likes to hang out around blueberries and other Vaccinium type things.

Bedraggled Bee. We picture here Colletes willistoni, with mussy hair, something Colletes is prone to. For me this is mostly irritating, in that they don't clean up well for their pictures, for the bees, well, its hard to say, they are an old lineage and apparently great looking hair under all conditions was not their evolutionary priority.

A tiny little bee from Arizona. Conanthalictus is usually a specialist on small low growing plants in the waterleaf family. Collected by Tim McMahon or Don Harvey on one of their expeditions to the region. Note the lovely shades of the wing coloration that pop when you use a black background.

What a little lovely parasitic wasp in the Chalcididae clan. This one appears to be Conura dema, based on picture booking from bugguide.net. I am not sure if that is true or not, but it is a very reasonable match, but I will let experts determine and validate that identification. Captured at Blackwater National Wildlife Refuge in Dorchester County, Maryland.

Specialist: Colletes latitarsis, a lover of ground cherry,Physalis, a weedy plant, but a flowering one, and a native one, with its own set of the species that appear to only gather pollen and perhaps nectar from its flowers. This plant though is not uncommon, and occurs in many of the gardens.

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.

This bee collects pollen from the weedy, but native, Physalis or ground cherry plants. The flowers of this group are low and dangly and tend to be overlooked as does Colletes latitarsis. Likely more common than would appear as it rarely goes into traps and is hard to find unless hunted for directly. Joe Milone was the photographer.

Ah, Badllands National Parks. One of my favorite places. So very quiet with lots of bees tucked into subtle places. In some places .... huge densities. Here is the common Colletes phaceliae. Lovely in its slightly heart shaped face. Photo by Hannah Sutton.

Colletes pahceliae - As you might suspect it is a lover of the plant phaceliae. Many of the Colletes are tight plant specialists. Only feeding their babies the pollen from one group of plants. With that lifestyle comes your status becomes linked to the the status of those plants. The status of those native plants are a mirror of how we treat our environments.

I stopped by a pullout in the sandhills of Nebraska on my way to the Badlands one year and just did some collecting off the sweet clover and other mostly weedy plants that lined the dirt parking area and along the nearby rail road tracks....fantastically abundant with bees. This was one of them the relatively common Colletes robertsonii. Photo by Erick Hernandez.

A little series of pictures of Colletes robertsonii from the Sandhills of Nebraska...Hooker county. A Midwestern species, this male and female were found in a nice patch of flowers along the road in a small pull off. Lovely country...the Sandhills. Photos by Erick Hernandez.

Not a great specimen, but then again, the species is one we have seen only a few times... you get what you can take. As the name implies there MIGHT be a relationship between this species and golden rod. Is that true? Someone needs to look at little more deeply and perhaps look at the pollen on the bodies of these bees to make such declarations.
