Eresus, also called ladybird spiders, is a genus of velvet spiders (family Eresidae) that was first described by Charles Athanase Walckenaer in 1805. Members of the genus formerly called Eresus cinnaberinus or Eresus niger are now placed in one of three species: Eresus kollari, Eresus sandaliatus and Eresus moravicus. A new species Eresus urus (named after the ancient Mesopotamian city of Ur), was discovered in southern Iraq in March 2025.
