Description
The spider is brownish-black coloured,[1] has 8 eyes, and is {{convert|3|-|4|mm}} in size.[2] The sexes are similar in size but the males have a small, but more slender abdomen compared to the female, with larger black palps.[3][4]
Species history
The species, originally found throughout north and west Asia,[5] is an introduced species in North America, first documented there in the 1950s or 1960s. Their success can be attributed to colonizing man-made structures, which provide refuge and camouflage for the mottled brown-and-grey spiders. This species also capitalizes on the artificial lighting found on many buildings, which attracts prey at night, thereby providing these visually-acute spiders with extended foraging opportunities.[6]
