For the first time, federal wildlife authorities this week have sought protection for a bee species under the Endangered Species Act.
The rusty patched bumblebee was once easy to find in the Midwest and eastern United States. Since the 1990s, its numbers have dropped by 87 percent, according to the U.S. Fish and Wildlife Service. Like many wild native bee species in the country, the bee has declined due to pesticide use, habitat loss and climate change, which has affected flowers it depends on.
