The Center for Biological Diversity (CBD) filed a lawsuit challenging the U.S. Fish & Wildlife Service’s delay in publishing a finding of whether the imperiled Suckley’s cuckoo bumblebee warrants Endangered Species Act protection. Suckley’s cuckoo bumblebees are a species of parasitic pollinators who play an important role in keeping other bee populations healthy. CBD is seeking declaratory judgment and injunctive relief.
