A type of bumblebee native to North America may soon be named to the endangered species list. It would be the first bee species to be considered endangered in the United States.
The U.S. Fish and Wildlife Service on Thursday formally proposed that the Bombus affinis, or rusty patched bumblebee, be listed as endangered under the guidelines of the Endangered Species Act.
"As pollinators, rusty patched bumblebees contribute to our food security and the healthy functioning of our ecosystems," the Fish and Wildlife Service said in a statement. The federal agency estimates that native insect species, particularly bees, contribute $3 billion in economic value annually in the United States. Because of a specialized pollen-shedding movement called "buzz pollination," bumblebee species are better at pollinating some crops than honeybees.
