Aethes williana, commonly known as the silver carrot conch, is a species of moth belonging to the family Tortricidae. It was first described by Nikolaus Joseph Brahm in 1791. This species can be found across most of Europe, as well as Trans-Caspia, Asia Minor, Mongolia, north-western Africa, and Iran. It inhabits dry, sandy, and chalky habitats. The wingspan of adult Aethes williana measures 13–17 millimetres (0.51–0.67 inches). Adult moths are active on the wing from May to early August. The larvae of Aethes williana feed on Daucus carota, Helichrysum arenarium, Helichrysum stoechas, Eryngium campestre, Eryngium maritimum, all species in the genus Gnaphalium, and Ferula communis.
