Don’t swat that fly! It might be Beyoncé! A horsefly with a distinctive golden hue is named after the singer—Plinthina beyonceae—and hundreds of other bugs and plants also have celebrity-inspired names. Why? Taxonomists, the scientists who group organisms into categories, often get to decide what to call new species, and sometimes they have a little fun. Aleiodes falloni, for example, is a wasp named for Jimmy Fallon, and a fern species has been dubbed Gaga monstraparva, for Lady Gaga and her fans, known as the “Little Monsters.” Bryan Lessard, the Australian taxonomist who named the Beyoncé fly, says that in addition to shouting out to larger-than-life celebrities, he aims for something bigger: “I hoped to inspire and generate buzz in the younger generation of scientists and taxonomists.”
