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]
The ladybird spider's body, as with most velvet spiders, somewhat resembles those of species in the jumping spider family. The male has a highly contrasting black and orange-red coloration, while the female is completely black. The opisthosoma looks velvety, as the species's common name would imply. [4]
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.
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 ...
The RSPB is highlighting some of the year’s conservation successes as it warns of the challenges nature faces in 2025.
Velvet spiders (family Eresidae) are a small group (about 100 species in 9 genera [1]) of spiders almost entirely limited to the Old World, with the exception of one species known from Brazil. In Europe, some are commonly called the ladybird spiders .
That would be the mysterious sea spider. With over 1,300 species living in every ocean, these marine arthropods can have a leg span ranging from .04 inches to nearly three feet long. The video ...
Their strikingly pink webs are built below rocks. One egg sac contains several hundred eggs, and spiderlings seem to disperse much more than other Eresus species (using ballooning), so that they are not found in large clusters.
