O. navus see text Wall spider is the common name for members of the genus Oecobius in the family Oecobiidae.

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.

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).
