Oecobius navus
Oecobius navus is a small cosmopolitan cribellate spider species of about 2-3mm. It is light grey with darkly annulated legs. It builds flat webs with lateral openings with a diameter of about 3 cm under rocks, on ceilings and along the corners of walls with protruding signaling threads.
Although this species is sometimes called O. annulipes, there is also a species of that name that only occurs in Algeria. Common names for these spiders are wall spider, baseboard spider and stucco spider.
