First Bumblebee Declared Endangered in U.S.

For the first time in the United States, a species of bumblebee is endangered.
The U.S. Fish and Wildlife Service announced Tuesday on its website that the rusty patched bumblebee (Bombus affinis), once a common sight, is “now balancing precariously on the brink of extinction.” Over the past two decades, the bumblebee’s population has declined 87 percent, according to the announcement.
The news comes just a few months after the first ever bees were declared endangered in the U.S. In September, seven species of Hawaiian bees, including the yellow-faced bee (Hylaeus anthracinus), received protectionunder the Endangered Species Act. (Read “For the First Time, Bees Declared Endangered in the U.S.”)
 The threats facing those seven species are similar to the ones that have depleted rusty patched bumblebee populations: loss of habitat, diseases and parasites, pesticides, and climate change. This is a big deal not only for bees but for humans, too—after all, bees pollinate a lot of our food.
“Bumblebees are among the most important pollinators of crops such as blueberries, cranberries, and clover and almost the only insect pollinators of tomatoes,” according to the U.S. Fish and Wildlife Service’s rusty patched bumblebee profile. “The economic value of pollination services provided by native insects (mostly bees) is estimated at $3 billion per year in the United States.” (See seven intimate pictures that reveal the beauty of bees.)
