Lace webbed spider is a name given to two common species of house spiders of the genus Amaurobius; A. similis and A. fenestralis. The spiders are often found near windows hence the Latin root of the name A. fenestralis with A. similis later defined as a separate but similar species and being named accordingly. Lace webbed spiders vary in body size from 7 mm to 12 mm with large strong legs. While the species are similar with the young virtually indistinguishable A.
