Cataglyphis, or desert ants, is a genus of ant in the subfamily Formicinae. Its most famous species is C. bicolor, the Sahara Desert ant, which runs on hot sand to find insects that died of heat exhaustion, and can, like other several other Cataglyphis species, sustain body temperatures of up to 50 °C. Cataglyphis is also the name of an autonomous rover that won the NASA Sample Return Robot Centennial Challenge inspired by the navigation approaches used by desert ants.
