A Pollinator with a New Name

Jun 18, 2014

We're almost midway through National Pollinator Week

It's a week that we should celebrate every day.

Last weekend we spotted a newcomer to our backyard bee garden: a bumble bee species, Bombus fervidus, formerly known as Bombus californicus, as identified by native pollinator specialist Robbin Thorp, emeritus professor of entomology at the University of California, Davis, and bumble bee enthusiast Gary Zamzow of Davis.

The female was heading toward a purple coneflower, Echinacea purpurea, and then touched down in a "Queen-of-the-Mountain" moment.

This bumble bee species is commonly known as "the yellow bumble bee," according to the co-authors of the newly published Bumble Bees of North America: an Identification Guide, authored by Paul Williams, Robbin Thorp, Leif Richardson and Sheila Colla (Princeton University Press).

It's widely spread across the continent. "Evidence from DNA barcodes supports a close relationship between individuals with the darker color pattern in the west (named californicus) and individuals with the lighter color patterns in the east (named fervidus)," they wrote.

So, despite the images of californicus all over the web, including BugGuide.net and discoverlife.org, it and fervidus appear to be the same species.

Who knew? DNA.
