The hobo spider is a member of the family of spiders known colloquially as funnel web spiders, but not to be confused with the Australian funnel-web spider. Individuals construct a funnel-shaped structure of silk sheeting and lie in wait at the small end of the funnel for prey insects to blunder onto their webs. Hobo spiders sometimes build their webs in or around human habitations. The hobo spider lays its eggs in September and they hatch during late spring. After the male hobo spider mates it dies.
Atracidae is a family of mygalomorph spiders, commonly known as Australian funnel-web spiders or atracids. It has been included as a subfamily of the Hexathelidae, but is now recognized as a separate family. All members of the family are native to Australia. Atracidae consists of three genera: Atrax, Hadronyche, and Illawarra, comprising 35 species. Some members of the family produce venom that is dangerous to humans, and bites by spiders of six of the species have caused severe injuries to victims. The bites of the Sydney funnel-web spider and northern tree-dwelling funnel-web spider are potentially deadly, but no fatalities have occurred since the introduction of modern first-aid techniques and antivenom.
Uloboridae is a family of non-venomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body.
The Agelenidae are a large family of spiders in the suborder Araneomorphae. Well-known examples include the common "grass spiders" of the genus Agelenopsis. Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider may be medically significant, and some evidence suggests it might cause necrotic lesions, but the matter remains subject to debate. The most widely accepted common name for members of the family is funnel weaver.
Hexathelidae is a family of mygalomorph spiders. It is one of a number of families and genera of spiders known as funnel-web spiders. In 2018, the family was substantially reduced in size by genera being moved to three separate families: Atracidae, Macrothelidae and Porrhothelidae. Atracidae includes the most venomous species formerly placed in Hexathelidae.
Eresus, also called ladybird spiders, is a genus of velvet spiders that was first described by Charles Athanase Walckenaer in 1805. Members of the genus formerly called Eresus cinnaberinus or Eresus niger are now placed in one of three species: Eresus kollari, Eresus sandaliatus and Eresus moravicus.
Atrax is a genus of venomous Australian funnel web spiders that was first described by O. Pickard-Cambridge in 1877 from the type species Atrax robustus. As of May 2019 it contains only three species: A. robustus, A. sutherlandi, and A. yorkmainorum. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, then to the Australian funnel-web spiders in 2018.
Hadronyche is a genus of venomous Australian funnel-web spiders that was first described by L. Koch in 1873. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, then to the Atracidae in 2018.
Missulena is a genus of mygalomorph spiders in the family Actinopodidae. It was first described by Charles Walckenaer in 1805, and is a senior synonym of Eriodon. M. tussulena is found in Chile, but the rest are indigenous to Australia. They are sometimes referred to as "mouse spiders" from the now-disproven belief that they dig deep burrows similar to those of mice. Scotophaeus blackwalli is also called a "mouse spider", but it is smaller and not closely related.
Missulena occatoria, known as the red-headed mouse spider, is a species of spider found in Australia, from open forest to desert shrubland. It is the most widely distributed Missulena species, occurring throughout mainland Australia. This is possible because the spiderlings disperse via wind (ballooning). Normally this only occurs with araneomorph spiders, mygalomorph spiders normally disperse by walking. Missulena venom may be very toxic, but few cases of serious envenomation have been recorded. Most recorded bites only caused minor effects, with Australian funnel-web spider antivenom having proved effective as a treatment.
Macrothele is a genus of mygalomorph spiders in the family Macrothelidae, and was first described by A. Ausserer in 1871. Most species occur in Asia, from India to Japan, and Java, with five found in Africa, and two in Europe. The name is derived from Ancient Greek μακρός ("makro-"), meaning "big", and θηλή ("thele"), referring to the spinnerets.
Chalybion californicum, the common blue mud dauber of North America, is a metallic blue species of mud dauber wasp first described by Henri Louis Frédéric de Saussure in 1867. It is not normally aggressive towards humans. It is similar in shape and colour to the steel-blue cricket hunter. Like other types of wasps, males do not have an ovipositor, and therefore cannot sting. It is ranged from northern Mexico to southern Canada, including most of the United States. It has also been introduced to regions including Hawaii, Bermuda, Croatia and other European countries.
The Iberian frog, also known as Iberian stream frog, is a species of frog in the family Ranidae found in Portugal and Spain. Its natural habitats are rivers, mountain streams and swamps. It is threatened by habitat loss, introduced species, climate change, water contamination, and increased ultraviolet radiation.
Eresus kollari, the ladybird spider, is a spider species in the family Eresidae. It was first described by Walckenaer in 1802, though it was misidentified. It was later correctly described by Rossi in 1846. It is one of the three species into which Eresus cinnaberinus or Eresus niger has been divided. It is thought to be endangered.
Porrhothele is a genus of mygalomorph spiders endemic to New Zealand. They are the only members of the family Porrhothelidae. They were first described by Eugène Louis Simon in 1892. Originally placed with the curtain web spiders, it was moved to the Hexathelidae in 1980, they were placed in their own family in 2018.
Thyreophora cynophila, commonly known as the bone skipper is a species of fly native to Europe. It was once thought to be the first fly to be driven to extinction by humans, but rediscovered in 2009. It has a bright orange head, and is associated with animal carcasses where the bones are broken open.
Cubanana is a monotypic genus of tarantulas containing the single species, Cubanana cristinae. It was first described by D. Ortiz in 2008, and is endemic to Cuba, occurring in the east of the island.
Aphonopelma anitahoffmannae is a species of spider in the family Theraphosidae, found in Mexico.
Macrothelidae is a family of mygalomorph spiders, split off from the family Hexathelidae in 2018. It contains three genera, Macrothele,Vacrothele and the extinct Promacrothele.
Steatoda paykulliana is a species of false black widow spider in the tangle-web spiders family, native to the Mediterranean countries, Southern Europe and Western Asia. The species is named in honor of the Swedish naturalist Gustaf von Paykull (1757–1826).
