'''Wall spider''' is the common name for members of the genus '''''Oecobius'''''. The members of these several species are all very small [[Spider|spiders]] that make small flat webs over crevices in walls and in similar spaces. They possess an organ called a [[cribellum]], which is a kind of comb-like device used to separate fibers of [[silk]] drawn from its spinnerets into many extremely fine fibers. Those fibers are so small in diameter that prey insects easily become entangled in them. The spiders then bite them before they can get away.

Wall spider is the common name for members of the genus Oecobius in the family Oecobiidae. The members of these several species are all small spiders that make small flat webs over crevices in walls and in similar spaces. They are cribellate spiders, meaning that they produce silk through a sieve-like plate of many parallel spigots, so that it emerges in a bundle of many invisibly fine parallel fibres with no adhesive covering to glue them together. Instead the bundles part into separate woolly cables that readily entangle small prey items, such as ants, that run into them. The spider sits in middle of the web, and when it is disturbed by suitable prey, it runs out and circles the prey with more silk to tangle it further. It subdues the prey by biting it, and carries one or more items bundled in silk, seeking a refuge where it can feed.

One cosmopolitan species is O. navus (sometimes also called O. annulipes).

One species of interest is Oecobius civitas. When a spider enters the home of another spider, rather than defend itself, the resident leaves to find another one.[1]
