Trogloraptor is a genus of large spiders found in the caves of southwestern Oregon. It is the sole genus in the family Trogloraptoridae, and includes only one species, Trogloraptor marchingtoni. [1] These spiders are predominantly yellow-brown in color with a maximum leg span of 3 in (7.6 cm).
Antrodiaetidae, also known as folding trapdoor spiders or folding-door spiders, is a small spider family related to atypical tarantulas. They are found almost exclusively in the western and midwestern United States, from California to Washington and east to the Appalachian Mountains . [ 1 ]
These spiders usually have markings on the dorsal side of their cephalothorax, with a black line coming from it that looks like a violin with the neck of the violin pointing to the rear of the spider, resulting in the nicknames fiddleback spider, brown fiddler, or violin spider.
The Australian funnel-web spiders (family Atracidae), such as the Sydney funnel-web spider Atrax robustus (a mygalomorph spider, not to be confused with the araneomorph funnel-weaver or grass spiders) are regarded as among the most venomous in the world. They react vigorously to threats and, reputedly, will more often attempt to bite than run away.
They spend much of their day basking in the sun. Their diet ranges widely, including spiders and beetles. Western Skinks will bite if grasped and will flee if they feel threatened. It is a common but secretive species whose range extends throughout Washington, Oregon, Nevada, Utah, and Wyoming and into western Montana and northern Arizona. [44]
Steatoda nobilis has a brown bulbous abdomen with cream coloured markings that are often likened to the shape of a skull. [11] Their legs are reddish-orange. [12] Both female and male S. nobilis can be distinguished from other spiders of the same genus by their large size and typical colouration.
Phidippus audax are commonly referred to as "bold jumping spiders" or "bold jumpers". [8] The species name, audax, is a Latin adjective meaning "audacious" or "bold".
