Attulus fasciger is a species of spider from the family Salticidae native to northern and western Asia. However, it has also been introduced to North America. [1]
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]
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]
