Bombus occidentalis, female, Wyoming, Yellowstone National Park

Here is a shot of part of a box of sparrows picked up by the Lights Out DC group in Washington D.C. this Fall migration after colliding with office buildings near Capitol Hill and the Visitor's Center.

Acer negundo - The very tip of bud leafing out ... its spring, why not. Upper Marlboro, Maryland. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200. .

Brachyhesma species, Australian Minute Bee, specimen collected in AustraliaLong: Until recently those who worked on the taxonomy of bees, or taxonomy in general for that matter, were men. Culturally that imbalance is now shifting, though we clearly still have a ways to go.

Agrilus ruficollis from my backyard. Likely from my moth sheet, but am running through my backlog of pictures and can't recall.

Power...This is Bombus citrinus, a female just emerged from where she hibernated overwinter and looking for the new nests of a queen bumblebee, note the sting on the prominent tail end of this bee, she uses that to eliminate or paralyze the female of another bumblebee, taking over the nest and essentially enslaving the daughters of the queen to now raise her young.

The odd case of Bombus citrinus. This species is a nest parasite on other Bumble Bees and as is the case in many, if perhaps not all, the parasitic species it has an unusually long top of the head...in other words the distance from the ocelli to the back of the head is longer than in other species.

A parasite of other bumblebeeds, B. citrinus, is the most common parasitic species in the East, but, as a parasite this still means it is very uncommon. The tale is simple, this species invades a nest, eliminates queen, and makes workers raise its own young.

Parasite. Nest parasite to be exact. Formerly in the genus Psithyrus these bees are now in the genus Bombus, with the rest of the bumble bees.

Bombus fraternus - Here is one of the very uncommon bumblebees that are of great concern these days, due to introduced parasites that have caused this species and its sister taxa to crash. Fortunately, they are still around, at least in small numbers.

Ceratina guarnacciana, female, Dominican Republic

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.

GIANT Ceratina from Puntarenas, Costa Rica, biggest I have ever seen. Collected by Valerie Peters. Check out the flange on the lower cheek of the side shot. Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200.

A male Ceratina species from Bee Gardens in San Francisco that are surveyed for bees by Jaime Palawek. This crisp litte bee is less than the size of a grain of rice (white, long grain) and glitters with smooth metallic blueish green colors. Glinty enough to be problematic when photographing.

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.
