Agroeca pratensisAgroeca pratensis was described by Emerton in 1890 as a member of the family Drassidae; shortly thereafter, in 1897, Simon designated it a member of the Liocraninae, a subfamily of the Clubionidae (historically, a rather unstable taxon). When the Clubionidae was split apart by Lehtinen in 1967, the subfamily was elevated to family level. While the males of A. pratensis have been confused with those of A. ornata, The epigynum of the two species is decidedly different. ............

Parasteatoda tepidariorum
common house spider
Described by Koch in 1841 as Theridion t., it has also been named Therideum t., and Achearanea t. Its placement in Parasteadoa based on its secondary genital organs (Saaristo, 2006) is considered "controversial" (Eberhard, 2020) by some, and thus may be considered fluid at this writing (Jan 2121). Colors are extremely variable, from back to white and almost everything in between. The abdominal pattern is notably mottled, sometimes appearing reticulated. Males characteristically have reddish leg...rock outcrops, buildings, windows, corners of rooms..........
