White-tailed Spider
White-tailed spiders are spiders native to southern and eastern Australia, and so named because of the whitish tips at the end of their abdomens. The body size is up to 18 mm, with a leg-span of 28 mm. Common species are ''Lampona cylindrata'' and ''Lampona murina''. Both these species have been introduced into New Zealand. White-tailed spiders are vagrant hunters that seek out and envenom prey rather than spinning a web to capture it; their preferred prey is other spiders. They are reported to bite humans, with effects including a red mark, and local itchiness, swelling and pain. On rare occasions, bites can cause nausea, vomiting, malaise or headache. Although ulcers and necrosis have been attributed to the bites, a scientific study by Isbister and Gray (2003) showed they had other causes, mostly infections. A study of 130 white-tailed spider bites found no necrotic ulcers or confirmed infections. Taxonomy Ludwig Carl Christian Koch described ''Lampona cylindrat ...

Ludwig Carl Christian Koch
Ludwig Carl Christian Koch (8 November 1825 – 1 November 1908) was a German entomologist and arachnologist. He was born in Regensburg, Germany, and died in Nuremberg, Germany. He studied in Nuremberg, initially law, but then turned to medicine and science. From 1850, he practiced as a physician in the Wöhrd district of Nuremberg. He is considered among the four most influential scientists on insects and spiders in the second half of the 19th century. He wrote numerous works on the arachinoids of Europe, Siberia, and Australia. His work earned him worldwide reputation as "Spider Koch". Sometimes confused with his father Carl Ludwig Koch (1778–1857), another famous arachnologist, his name is abbreviated L.Koch on species descriptions; his father's name is abbreviated C.L.Koch Pierre Bonnet. ''Bibliographia araneorum,'' (1945) Les frères Doularoude (Toulouse). Works ''Die Arachniden Australiens'' (1871-1883), his major work on Australian spiders, was completed by Eugen ...

Brown Recluse Spider Bite
Loxoscelism () is a condition occasionally produced by the bite of the recluse spiders (genus ''Loxosceles''). The area becomes dusky and a shallow open sore forms as the skin around the bite dies (necrosis). It is the only proven type of necrotic arachnidism in humans. While there is no known therapy effective for loxoscelism, there has been research on antibiotics, surgical timing, hyperbaric oxygen, potential antivenoms and vaccines. Because of the number of diseases that may mimic loxoscelism, it is frequently misdiagnosed by physicians. Loxoscelism was first described in the United States in 1879 in Tennessee. Although there are up to 13 different ''Loxosceles'' species in North America (11 native and two nonnative), ''Loxosceles reclusa'' is the species most often involved in serious envenomation. ''L. reclusa'' has a limited habitat that includes the Southeast United States. In South America, '' L. laeta'', '' L. intermedia'' (found in Brazil and Argentina), and '' L. ga ...

Spiders Of New Zealand
New Zealand has 1157 described spider species, with an estimated total fauna of 2000 species. Over 97 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions. The New Zealand spider with the largest leg span is the Nelson cave spider (''Spelungula cavernicola''), with a leg span of up to and a body length. The Australian white-tailed spider, first recorded in New Zealand in 1886, has been falsely attributed as the cause of many necrotising spider bites. The flat huntsman spider (''Delena cancerides''), also from Australia, and called the Avondale spider in New Zealand, was accidentally introduced in the early 1920s, possibly in shipments of hardwood logs used for railway sleepers.Rowell and Avilés (1995).

Spiders Of Australia
Australia has a number of highly venomous spiders, including the Sydney funnel-web spider, its relatives in the family Hexathelidae, and the redback spider, whose bites can be extremely painful and have historically been linked with deaths in medical records. Most Australian spiders do not have venom that is considered to be dangerously toxic. No deaths caused by spider bites in Australia have been substantiated by a coronial inquest since 1979. There are sensationalised news reports regarding Australian spiders that fail to cite evidence. ''A Field Guide to Spiders of Australia'' published by CSIRO Publishing in 2017 featuring around 836 species illustrated with photographs of live animals, around 381 genera and 78 families, introduced significant updates to taxonomy from Ramirez, Wheeler and Dmitrov Estimates put the total number of Australian spider species at about 10,000. Only around 3,600 have been described. Little information is known about many undiscovered species. New s ...

Lamponidae
Lamponidae is a family of spiders first described by Eugène Simon in 1893. It contains about 200 described species in 23 genera, most of which are endemic to Australia, with the genus ''Centrocalia'' endemic to New Caledonia, and two ''Lampona'' species (''L. cylindrata'', ''L. murina'') also occurring in New Zealand where it is commonly known as the "White Tail" spider. ''Lampona papua'' is endemic to New Guinea, where two otherwise Australian species (''Centrothele mutica'', ''Lamponova wau'') also occur.

Arachnologist
Arachnology is the scientific study of arachnids, which comprise spiders and related invertebrates such as scorpions, pseudoscorpions, and harvestmen. Those who study spiders and other arachnids are arachnologists. More narrowly, the study of spiders alone ( order Araneae) is known as araneology. The word "arachnology" derives from Greek , ''arachnē'', "spider"; and , ''-logia'', "the study of a particular subject". Arachnology as a science Arachnologists are primarily responsible for classifying arachnids and studying aspects of their biology. In the popular imagination, they are sometimes referred to as spider experts. Disciplines within arachnology include naming species and determining their evolutionary relationships to one another (taxonomy and systematics), studying how they interact with other members of their species and/or their environment (behavioural ecology), or how they are distributed in different regions and habitats (faunistics). Other arachnologists perform ...

Colonisation
Colonization, or colonisation, constitutes large-scale population movements wherein migrants maintain strong links with their, or their ancestors', former country – by such links, gain advantage over other inhabitants of the territory. When colonization takes place under the protection of colonial structures, it may be termed settler colonialism. This often involves the settlers dispossessing indigenous inhabitants, or instituting legal and other structures which disadvantage them. Colonization can be defined as a process of establishing foreign control over target territories or peoples for the purpose of cultivation, often by establishing colonies and possibly by settling them. In colonies established by Western European countries in the Americas, Australia, and New Zealand, settlers (supplemented by Central European, Eastern European, Asian, and African people) eventually formed a large majority of the population after assimilating, warring with, or driving away indig ...

Recluse Spider
The recluse spiders (''Loxosceles'' (), also known as brown spiders, fiddle-backs, violin spiders, and reapers, is a genus of spiders that was first described by R. T. Lowe in 1832. They are venomous spiders known for their bite, which sometimes produces a characteristic set of symptoms known as loxoscelism. Recluse spiders are now identified as members of the family Sicariidae, having formerly been placed in their own family, the Loxoscelidae. Although recluse spiders are feared, they are usually not aggressive. Relation with other spiders Sicariidae are of the superfamily Scytodoidea. Other families in the Scytodoidea include Drymusidae, Scytodidae, and Periegopidae. Habitat and appearance ''Loxosceles'' is distributed nearly worldwide in warmer areas. All have six eyes arranged in three groups of two (dyads) and some are brownish with a darker brown characteristic violin marking on the cephalothorax. However, the "violin marking" cannot be used as a reliable way to ident ...
