Roy Orbison and Darth Vader have in common? All three have had new beetle species named after them.
Naming species after celebrities is one seriously effective way for scientists to draw attention to taxonomy. Giving species a famous name for more public interest is "shameless self-promotion," says Quentin Wheeler, the director of the International Institute for Species Exploration in Arizona (whose names populate four of our top-15 list). "When you are a taxonomist and are mentioned in
Scientists are given free rein with naming, as long as they abide by guidelines set by the International Code of Zoological Nomenclature. The rules for patronyms—or scientific names in honor of people—do not limit which names are used. They just provide a uniform naming method. In general, an animal species ending in 'i' is named after one man. The ending 'ae' is for species named after one woman; 'orum' is reserved for species named after couples. Plant species operate under slightly different rules because the gender of the species must match that of the genus.
President Barack Obama is one of the latest to be immortalized in the taxonomic record. And the list of famous plants, bacteria and animals ranges in the hundreds, if not thousands—from the sea of many, here are our 18 favorite famous namesakes.
1. Barack Obama: Caloplaca obamae

Our current president's namesake is an orange-colored lichen. Discovered in California, the lichen was named this March. Kerry Knudsen, the lichen curator in the University of California, Riverside Herbarium, picked the name to "show my appreciation for the president's support of science and science education."
2, 3 and 4. George W. Bush, Agathidium bushi; Dick Cheney, Agathidium cheneyi; and Donald Rumsfeld, Agathidium rumsfeldi

All three members of the former administration have a slime-mold beetle named in their honor. Wheeler is responsible for this choice, which was meant as a compliment. He said President Bush called to thank him for the gesture.
5. Darth Vader: Agathidium vaderi

Wheeler named another slime-mold beetle in honor of the fictional
Star Wars villain. The reasoning is that both Darth Vader and his namesake have broad, shiny heads and similar eyes.
6. Roy and Barbara Orbison: Orectochilus orbisonorum

In January of last year Wheeler and his colleagues named a whirligig beetle after legendary singer song-writer, Roy Orbison and his widow, Barbara Orbison. The beetle looks as if it is wearing a tuxedo.
7 and 8. Stephen Colbert: Aptostichus stephencolberti and Agaporomorphus colberti

The comedian, who has begged scientists to name species after him on
The Colbert Report, has been honored twice—once with a spider and once with a Venezuelan diving beetle. The beetle species is notable for its male reproductive organs, which display a unique row of fine hairs.
9, 10 and 11. Frank Zappa: Phialella zappai (jellyfish), Pachygnatha zappa (spider), Zappa, a genus of Gobiidae (fish)

Guitarist, free-speech advocate and prolific song writer Frank Zappa is a popular inspiration for a number of species' names. In 1987, a scientist named a species of jellyfish after Zappa because he wanted to meet the artist (his plan worked). Next, scientists named an entire genus of goby fish was after the musician, followed by an orb-weaver spider whose black markings reminded the researchers of Zappa's signature mustache.
