Eresus
2 species
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.
They are found in Europe, Asia, and Africa, usually in non-forested warm and dry habitats. Their life cycle is completed in 3–4 years, after they undergo dispersion and reach a juvenile state and turn into predators. Some species build a vertical burrow which is lined with silk, the opening being camouflaged with a silken sheet of debris. While some species don't build a burrow and just make their tubes under stones.
