The Spiders of Europe and Greenland
Family: Oonopidae (Dwarf Cell Spiders)
Biology: Some species occurring in North and Central Europe are introduced to greenhouses and other buildings from warmer regions.
Characters of family: The members of this family are rather small, about 2 mm in body length. They have only six, relatively large eyes that are virtually contigous and situated on a narrow head, marginally wider than the eyegroup. The species are generally coloured in shades of red, pink and orange.

Genus: Oonops Templeton, 1835

Oonops domesticus Dalmas, 1916
Description: Oonops domesticus is easily recognised by its red colour and way of walking, which alternates between slow walks and short runs. This is particularly evident if the spider is gently disturbed. The species is one of only about five Danish spiders with six eyes, the remaining more than 500 species having eight. The eyes of Oonops domesticus are pearly indicating this is a nocturnal species. Size: Female 2 mm; male 1.5 mm. Maturity: All year. Habitat: The species lives exclusively within houses and rare outdoor findings are supposedly stray specimens. Range: Belgium, Denmark, France (Mainland), Germany, Great Britain (Mainland), Ireland, Italy (Mainland), Netherlands, Poland, Portugal (Azores), Portugal (Mainland), Slovakia, Switzerland, Ukraine (van Helsdingen 2009.1).
