About Pseudeuophrys lanigera (Simon, 1871)
Males of Pseudeuophrys lanigera reach a body length of three to four millimeters, while females can grow up to five millimeters. This species is very similar to Pseueuophrys erratica, which is rarer and found under the bark of trees on forest fringes. Unlike P. erratica, P. lanigera is mostly found inside buildings, so adults can still be found even in deep winter. It is better adapted to the dry climate of modern concrete architecture than other jumping spiders in the area, such as Salticus scenicus. Adults of this species can be found year-round. Pseudeuophrys lanigera is distributed across western and southern Europe, ranging eastward as far as the Caucasus. In Germany, this species is most often observed inside houses, or on the external walls of buildings, indicating that it is synanthropic at least in some parts of its range. The first recorded finding of P. lanigera in Romania was published in 2007, while the first recorded finding in Poland was in 1999. The species was originally distributed only in Southwest Europe, and was first recorded in Germany in the 1950s. In Germany now, it is only found in or near human dwellings.
