Additional information

In tropics and subtropics in the Old World, in Mediterranean area in Italy and France in the open land, in Great Britain, Central and North Europe imported to greenhouses in many cases. They were thought to develop parthenogenetically in greenhouses, as it seems that only females occur, but this must be doubted because of the cryptic living of males.

Oxford (2011) showed convincingly that Uloborus plumipes is not parthenogenetic in urban populations in Europe (and probably nowhere else).

Since a few decades, this species shows some spreading tendencies within Europe. Nevertheless, it shall not be listed as alien or invasive because it is native for Europe.

Frequency: Widely distributed
