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 partly into separate onto 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]
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs.
Linyphiidae, spiders commonly known as sheet weavers, or money spiders is a family of very small spiders comprising 4706 described species in 620 genera worldwide. This makes Linyphiidae the second largest family of spiders after the Salticidae. The family is poorly understood due to their small body size and wide distribution; new genera and species are still being discovered throughout the world. The newest such genus is Himalafurca from Nepal, formally described in April 2021 by Tanasevitch. Since it is so difficult to identify such tiny spiders, there are regular changes in taxonomy as species are combined or divided.
Xysticus is a genus of ground crab spiders described by C. L. Koch in 1835, belonging to the order Araneae, family Thomisidae. The genus name is derived from the Ancient Greek root xyst, meaning "scraped, scraper".
Salticus is a genus of the family Salticidae. Salticus is the type genus for the family Salticidae.
Ozyptila is a genus of crab spiders that was first described by Eugène Louis Simon in 1864. It has been misspelled as "Oxyptila" in multiple accounts.
Dysdera is a genus of woodlouse hunting spiders that was first described by Pierre André Latreille in 1804. They originated from Central Asia to Central Europe.
Oecobius navus is a small cosmopolitan cribellate spider species found across the world.
Theridion is a genus of tangle-web spiders with a worldwide distribution. Notable species are the Hawaiian happy face spider (T. grallator), named for the iconic symbol on its abdomen, and T. nigroannulatum, one of few spider species that lives in social groups, attacking prey en masse to overwhelm them as a team.
Walckenaeria is a genus of dwarf spiders that was first described by John Blackwall in 1833. It is a senior synonym of Paragonatium, as well as Wideria, Cornicularia, Prosopotheca, Tigellinus, and Trachynella.
Palliduphantes is a genus of dwarf spiders that was first described by Michael I. Saaristo & A. V. Tanasevitch in 2001.
Pelecopsis is a genus of dwarf spiders that was first described by Eugène Louis Simon in 1864.
Bassaniodes is a genus of crab spiders that was first described by Reginald Innes Pocock in 1903.
