The rusty patched bumblebee is the first bee to be listed as endangered in the continental US, and the western bumblebee has been the subject of extensive USGS work that has found effects of climate, land cover change, and pesticides on the decline of the species.

USGS biologist Stacy Simanonok captures a bumble bee in a net during a pollinator survey in the grasslands of the North Dakota plains. Researchers are testing environmental DNA sampling methods to determine if this less invasive way to survey for pollinators generates similar results as traditional netting methods.
