Bombus terrestris - A domesticated bee. Widely used in agriculture in green house pollination as well as in the field. Also one that has been introduced into several parts of the world... Causing major problems in South America where some combination of competition and disease harms the native bumble bees.

One of the species of bumble bees that have declined since the introduction of the pathogen Nosema bombi, but there are some suggestions that populations have managed to survive or increase a bit ,,,this one, captured by Laura Russo is at the southern edge of its range and a good sign for retention.

More black bumble bees from Yosemite National Park. Here is the male of Bombus vosnesenskii. This species was described by the relatively prolific Polish Taxonomist Oktawiusz Wincenty Bourmeister-Radoszkowski who pumped out a great many new descriptions of bees in many parts of the world.

A bit bedragled specimen of the bumble bee B. melanopygus from Yosemite National Park. We weren't quite up to speed on our hair dressing when we prepped this specimen. Part of Claire Kremen's study of the bees of the park. Photo by Anders Croft.

If you were in the Badlands of South Dakota in the Summer, and were paying attention to your bumblebees, you would see this one. Bombus nevadensis. It is big and the queens are extra beefy. This is one of the dark bumbles. More black on the sides of the body and tinted wings.

For some reason I have not put up a Bombus perplexus shot yet. Here is one that Wayne Boo did a couple of years ago and I am just now getting around to shopping. 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.

More Bombus perplexus shots, in this case...males. You can tell they are males because they have 13 rather than 12 antennal segments and the hind legs lack the pollen carrying corbicula (bare area) on the tibia. Lemon yellow though! Specimens from Central Pennyslvania from Laura Russo's study there. Photographs by Kelly Graninger.

Sections of a male Bombus perplexus, illustrating the hair and shape patterns. A regular, but somewhat uncommon bumble bee, that is noted for the more extensive yellow hairs on the thorax and abdomen than most bumble bee species. Photographs by Greta Forbes.

Let us present the first record of Bombus rufocinctus for the state of Pennsylvania. This is a not uncommon northern and western species....it just hasn't been found in PA as of yet. Some notes on its identification.

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.

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.

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.
