Citizen scientists tracking Ohio bumblebees

Nolly Dakroury, The Columbus Dispatch

Luciana Musetti is fascinated by bumblebees.

“They play a vital role to our environment, and they are beautiful, too,” Musetti, an entomologist and curator of the Triplehorn Insect Collection at Ohio State University’s Museum of Biological Diversity, said in an email.

When she can, she photographs them. That’s why she was excited to have stumbled upon bumblebeewatch.org, a website for citizen scientists devoted to tracking bumblebee populations in North America.

“The idea of the website is, if we can track where populations are now, we can start making conservation efforts,” said Rich Hatfield, one of the founders of the website.

Investigators collected as many as 400 dead bees, although witnesses said the total death toll could have been far larger.

The Oregonian previously reported about the Pettygrove incident, in which Portland law student Corinne Fletcher stepped outside her doorstep to find countless bumblebees dead or dying on a walkway leading into the park.

B. dahlbomii is, in fact, the world’s largest bumblebee. Native to the Patagonia region of Argentina and Chile, the queens of the species can reach an amazing four centimeters in length. That’s two to three times the size of one of the most recognizable North American species, the American bumblebee (B. pensylvanicus).
