Description

The spider is brownish-black coloured,[2] has 8 eyes, and is 3–4 millimetres (0.12–0.16 in) in size.[3] The sexes are similar in size but the males have a small, but more slender abdomen compared to the female, with larger black palps.[4][5]

Species history

The species, originally found throughout north and west Asia,[6] is an introduced species in North America and was 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.[7]
