Bumble Bee Conservation
Bumble bees are important pollinators of wild flowering plants and agricultural crops. They are able to fly in cooler temperatures and lower light levels than many other bees, making them excellent pollinators – especially at higher elevations and latitudes. They also perform a behavior called “buzz pollination,” in which the bee grabs the flower in her jaws and vibrates her wing muscles to dislodge pollen from the flower. Many plants, including a number of wildflowers and crops like tomatoes, peppers, and cranberries, benefit from buzz pollination.
Because they are essential pollinators, loss of bumble bees can have far ranging ecological consequences. Alarmingly, recent work by the Xerces Society in concert with IUCN Bumble Bee Specialist Group, indicates that some species have experienced rapid and dramatic declines more than others. While some species have received considerable conservation attention, other species such as the Suckley cuckoo bumble bee and the variable cuckoo bumble bee have been largely overlooked.
Bumble bees face many threats including habitat loss, disease, pesticide use, and climate change. Unlike honeybees which have large (>10,000 individuals) perennial hives, bumble bees produce smaller annual colonies (50-1,500 individuals). Due to their smaller annual population sizes, life cycle, and genetic makeup, they are uniquely susceptible to extinction.

A Ghost in the Making
Natural history photographer Clay Bolt is on a multi-year quest to tell the stories of our native bees, and one elusive species – the Rusty-patched Bumble Bee – has become his white whale. In January of 2013, the Xerces Society and partners filed a petition to list the rusty patched bumble bee as an endangered species under the US Endangered Species Act.
The film from Day’s Edge Productions and acclaimed nature photographer Clay Bolt illuminates the challenges faced by the critically endangered species. In conjunction with the film’s release, a change.org petition urging the US Fish and Wildlife Service to add the rusty patched bumble bee as an endangered species under the U.S. Endangered Species Act has gained over 125k signatures.
