And now we present a mystery. Here is a bumble bee collected in northern Virginia in a blue vane trap as part of T'ai Roulston's research group looking at bee populations in restored fields. The question at hand is what species is it? Its a clean, unworn bee, appears to be the size of large worker or perhaps a small queen and it fits some characteristics of B.

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.

Big-eyed Male Bombus nevadensis from Badlands National Park in South Dakota. Lots of mixups in databases because its old subspecies. B. n. auricomus was raised to species status, but that memo has not gotten out to all the database people. Databases seem so simple, if only taxonomists wouldn't change the names all the time.!

This bumblebee species has almost entirely disappeared from its West Coast range due to a recent epidemic sweeping through some bumblebee populations. However, the Rocky Mountain populations still persist and there is hope that the West Coast population will also recover and resume its place as one of the most common bumblebee species in the West.

What a lovely face. This bumblebee species has almost entirely disappeared from its West Coast range due to a recent epidemic sweeping through some bumblebee populations.

Ah, the lovely yellow of Bombus perplexus. For some reason this species' coloration tends towards bright yellow while other eastern bumbles are more subdued in their yellowness. It varies with their age (the sun fade bumbles plumage) but a nice lemon yellow usually means this species.

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.

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.

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.
