Eresus
''Eresus'', also called ladybird spiders, is a genus of velvet spiders 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''. Description They resemble both jumping spiders and the spiders in the Palpimanidae, as their bodies look similar, and are as well rather velvety. Males of this genus have a red abdomen, with black spotting, usually taking the form of 4 black spots. While the rest of the body is usually black, with some reddish areas or white areas. Females of this genus are duly colored usually being a grey, brown or black color. Some species having some yellow coloration, thought they are still significantly duller then the males. Identification Males of this genus can usually be distinguished by their unique abdominal pattern. Which in the lateral areas has two pair ...

Eresus Cinnaberinus
''Eresus cinnaberinus'' and ''Eresus niger'' are names formerly used for a group of spiders in the genus '' Eresus'' now divided into three species, '' E. kollari'', '' E. sandaliatus'' and '' E. moravicus''. The three species differ in size, colour pattern, shape of prosoma and copulatory organs, and habitat, with no morphologically intermediate forms. As eastern and western ''E. kollari'' are genetically different, with the eastern form likely a hybrid between "pure" ''E. kollari'' and ''E. moravicus'', it is possible that later revisions will partition it into additional species. Both ''Eresus cinnaberinus'' and ''Eresus niger'' are now regarded as ''nomina dubia''. Distributions * ''E. kollari'' has the widest distribution of the three species, occurring from Spain and Portugal to Novosibirsk in Russia. * ''E. moravicus'' occurs in the Pannonian region, the Balkan Peninsula and parts of the Austrian Alps The Central Eastern Alps (german: Zentralalpen or Zentrale Ostalpen) ...

Eresus Kollari
''Eresus kollari'', the ladybird spider, is a spider species in the family Eresidae. 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. It is thought to be endangered. Description Their body as most velvet spiders, resemble somewhat those in the jumping spider family. The males have a contrasting color, having a black and red coloration, while the females are completely black. The opisthosoma looks velvety, as their common name would imply. Colonies In colonies, they burrow up to 10 cm in depth. Which is usually covered in a funnel web. Females may carry lens shape egg sack containing up to 100 eggs. Which she’ll carry to a sunny place. The juveniles will stay in the females burrow and feed on her after she dies. They usually form small colonies with up to a couple dozen spiders, but they m ...

Eresus Moravicus
''Eresus moravicus'' is a spider species in the family Eresidae found in Austria, Hungary, Czechia, Serbia, Slovakia and Albania. Being found mainly in rocky steppes. It is named after the eastern part of the Czech Republic, Moravia, which is where the type species was found. ''E. moravicus'' is one of the three species into which '' Eresus cinnaberinus'' or ''Eresus niger'' has been divided. Description This is the largest '' Eresus'' species found in Central Europe, males are black and red in color. the first two legs are black, with the last two being red. The opisthosoma is red with the carapace being black. While the females are mostly black, except with orange hairs on the from part of the prosoma. Identification ''E. moravicus'' can be distinguished from the other two species by the totally red hind legs in males and the orange hairs on prosoma in females, among other features. To identify them from the Mediterranean species which also share this trait, it is sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eresus Sandaliatus
''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. Description Male ''E. sandaliatus'' are generally (a little bit smaller than other species of the ''E. cinnaberinus'' complex) and characterized by a bright orange back featuring four large and two small ebony spots. White hairs are never present on the back, and legs always lack red hairs. In contrast, the females are and jet-black. Habits Males enter the adult stage in early September, but overwinter in their webs and search for females only in May or June of the next year. Otherwise, this species is very similar to other species of ''E. cinnaberinus'' complex. After the 35-80 eggs hatch, the spiderlings receive a liquid from the mouth of ...
