The mysterious case of the Appalachian Rusty-patched Bumble Bee (Bombus affinis) holdouts. There are no more RPBB's in most of North American, people have looked, its not really a question of overlooking them any longer, they are just all gone. Fingers point to a set of introduced European bumble bee pathogens. And, ignoring the more famous residual population in the WI/MN/IA/IL area they still persist in the highland area between WV and VA. As proof. Here is a lovely picture of a Bombus affinis inadvertently collected by Mark Hepner recently in West Virginia. So, why do they persist in these two spots and no where else?

We Are Made One with What We Touch and See We are resolved into the supreme air, We are made one with what we touch and see, With our heart's blood each crimson sun is fair, With our young lives each spring impassioned tree Flames into green, the wildest beasts that range The moor our kinsmen are, all life is one, and all is change. - Oscar Wilde
