"These rare, striking beetles are in trouble and can only be saved by Endangered Species Act protection," said Noah Greenwald, endangered species director at the center.
The Southern Utah Wilderness Alliance first asked for beetle to be listed as an endangered species in 1994, which led the Fish and Wildlife Service to give it "candidate" status later that year.
The Coral Pink Sand Dunes tiger beetle is described as about a half inch in size with striking coloration predominantly white wing cases with a thin reddish band that runs down the length of its center and an upper thorax with a metallic sheen.
The service is accepting public comment on the proposal until Dec. 3.
