People think that identifying Bumble Bees are easy. They are big, there are "guides" that show the color patterns...so what could go wrong....well....things like this specimen of Bombus impatiens. It should have NO red / brown on it, but this specimens has 2 whole tergites that are reddish brown.

Bombus auricomus, A species regularly found in urban areas, but uncommon elsewhere, this one is from Baltimore along powerlines near the collectively owned Armistead Gardens

Philadelphia, Pennsylvania, collected at Morris Arboretum by Stephanie Wilson

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.

Some bumble bees are parasites. A common theme in the bee world...to the tune of about 20% of all the species. Why go to all that work gathering pollen when you can just lay your egg in someone else's nest. Then in an evolutionary spy vs.

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.

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.

The giant bumblebee (Bombus dahlbomii). A denizen of the southern Andes and widely believed to be in decline due to competition and perhaps spread of pathogens with two introduced European bumblebees that have invaded the region. You notice this bee when it flies by. Dramatically orange with yellow highlights on the traditional deep black integument of bumblebees.

A common northern Bumble bee, Bombus ternarius seems to be relatively unaffected by the pathogen Nosema bombi that has impacted many other species. While not very visible in this view (but visible elsewhere in our collection) this species show bright orange on its abdomen and often causes people to think they have B.

A bumble bee with issues. This is the Yellow-banded Bumble Bee. Or, scientifically, we call it Bombus terricola. Its one of a number of Bumbles in North America that have been penalized by the introduction of Nosema bombi, an inadvertent import from Europe.

A series of pictures of a queen and a male of the northernish bumble bee Bombus vagans. Still a reasonable common component of northern Appalachian systems, its been retreating from its lower elevation and southern edges over the last century.

One of the common and strikingly dark western bumble bees. This species largely restricted to coastal and Sierra ranges. The current specimen comes from Claire Kremen's study of Yosemite National Park bees. Photographs by Anders Croft.

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.
