An early spring Braconid Wasp in the Agathidinae subfamily (thanks to Bob Kula USDA for the det) captured 3/20/2014 in Beltsville, Maryland, often associated with the parasitization of Moth and Butterfly Larvae.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

Not all bumblebees gather pollen. Some, like this Bombus citrinus, take over the nests of other bumblebee species and use their workers to provision the nests of their young.

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.

A somewhat bedraggled Bombus crotchii from Yolo County, California..."This bee was collected in the California Central Valley in Yolo County for research on small-scale restoration in agricultural areas. Claire Kremen's 10-year study of hedgerows shows the benefits of planting native shrubs and forbs in agricultural areas for native bees.

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.

Check the eyes out on this male Bumble Bee. We already put up a spread of female B. fraternus, but the male has some pretty unique features for bumble bees. For one, the eyes are HUGE, they nearly meet at the top of the head. Only a few other bumbles do that...and the face is extremely short, with the mandibles almost joined to the bottom of the eyes.

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.

The most common of all the eastern Bumblebees, Bombus impatiens, is something of the cow/chicken/pig of the non-honeybee world. Now used throughout the continent to fertilize plants in greenhouse cultivation. Note the whitish rather than yellowish light colored hairs and that the first segment of the abdomen has light hairs, but remainder are black.

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.

More shots of a queen Bombus affinis...the newly minted endangered Bumble Bee. This specimen is from the National Collection at the Smithsonian and was collected in Racine, Wisconsin in 1965 when times were easy for this species. Collected by L.W.

This, I feel, is as piquant as a picture can be. We are a production shop, we parse thousands of insect specimens collected by many people. At times, like this one, specimens come in that are uncommon or part of a study (here from a survey of Hart-Miller Island by Gene Scarpulla) and you take what you get.

More from last year's expedition to Chile with Laurence Packer. Such a lovely country...we camped in a new place every day. Ping ponging from the Andes to the Coast sleeping along the road or in open pastures. Lovely people, easy travel, no problems with law enforcement people. This is a Caenohalictus species of some kind.

As the name implies this species from East of the Andes superficially resembles the parasitic bee genus Nomada. However for whatever reason they have chosen from the wardrobe of bee colors the same cloths they act quite differently. Of note is that both the males and females of this species gather oil in addition to the usual pollen and nectar.
