On October 16, 2018, the Xerces Society for Invertebrate Conservation, Defenders of Wildlife, and the Center for Food Safety submitted a petition to the California Fish and Game Commission (Commission) to list the Crotch bumble bee (Bombus crotchii), Franklin’s bumble bee (Bombus franklini), Suckely cuckoo bumble bee (Bombus suckleyi), and western bumble bee (Bombus occidentalis occidentalis) as endangered under the California Endangered Species Act.  The Commission is required under the California Fish and Game Code to refer the petition to the California Department of Fish and Wildlife for a recommendation to the Commission regarding the petition’s merits.
