Endangered Status The Delhi Sands Flower-loving Fly is on the U.S. Endangered Species List. It is classified as endangered in California. The first fly on the Endangered Species List, this species lives in sparsely vegetated sand dunes, where the adult consumes flower nectar. It now lives on only about two percent of its original range, squeezed out of its habitat by human population growth and development. It survives in a few sites in San Bernardino and Riverside Counties.
