Species history

The species, originally found throughout north and west Asia, 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.
