Eresus sandaliatus is a species of spider found primarily in northern and central Europe. Like other species of the genus Eresus, it is commonly called ladybird spider because of the coloration of the male. E. sandaliatus is one of the three species into which Eresus cinnaberinus or Eresus niger has been divided. [1]
Eresus kollari, the ladybird spider, [2] is a spider species in the family Eresidae. [1] It was first described by Walckenaer in 1802, though it was misidentified. It was later correctly described by Rossi in 1846. It is one of the three species into which Eresus cinnaberinus or Eresus niger has been divided. [3] It is thought to be endangered.
Eresus, also called ladybird spiders, [2] is a genus of velvet spiders (family Eresidae) that was first described by Charles Athanase Walckenaer in 1805. [3] 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.

The three species differ in size, colour pattern, shape of prosoma and copulatory organs, and habitat, with no morphologically intermediate forms.

As an anti-predator defense, spiders of the genus Eresus, known as ladybird spiders, have evolved to replicate the patterns of coccinellids. This is a form of Batesian mimicry, as the spiders lack the chemicals. This resemblance is limited to adult male spiders which are actively searching for females and exposed – unlike the females and ...
