Bees around the world have been having a rough time for several years. Populations are going down, even completely disappearing in some places. Researchers haven’t fully figured out what’s wrong; pesticides are among one of the possible culprits.

Now some good news from the Front Range about what’s called the Western Bumblebee. More and more are showing up in a multi-year study near Boulder. CU Boulder Professor Carol Kearns says it’s easy to spot them, because they have, well, white “butts,” or part of their abdomen. Kearns talks with Aspen Public Radio’s Elise Thatcher.
