Lycosa tarantula is the species originally known as the tarantula, a name that nowadays in English commonly refers to spiders in another family entirely, the Theraphosidae. It now may be better called the tarantula wolf spider, being in the wolf spider family, the Lycosidae. L. tarantula is a large species found in southern Europe, especially in the Apulia region of Italy and near the city of Taranto, from which it gets its name. [2]
Historical superstition has it that the spider's bite can produce severe symptoms called tarantism.
These spiders are rather large, the females being as large as 30 mm (1.18 in) in body length [3] and the males around 19 mm (0.75 in). As with other wolf spiders, the silken sac containing over 100 eggs is carried attached to the mother's spinnerets, and then after they hatch, the spiderlings climb on their mother's abdomen and ride around with her for some time until they are sufficiently mature to survive on their own. [3] After leaving their mother's protection, the young spiders disperse and dig burrows. Females live in their burrows all their lives except for nocturnal forays to capture prey, [3] but the mature males leave the protection of burrows and wander about looking for mates. The males can live for 2 years. The females can live for 4 years or more. Many sexual encounters (about one-third according to one study) end in the females cannibalizing the male instead. [4] During the winter, these spiders hibernate in their burrows.
They are a nocturnal species and generally lurk at the mouths of their burrows waiting for prey, so people are unlikely to encounter them. Unlike the Salticidae (jumping spiders), which may exhibit curiosity about humans and may be content to wander around on one's hand, the Lycosidae (wolf spiders) have a very strong tendency to flee at the approach of any large animal. They have quite good eyesight, so a human is unlikely to approach them unseen. Capturing them is relatively difficult, because they keep moving and can run very fast. When wolf spiders are cornered, they show no inclination to make threat displays, much less to advance on a human's hand with the intention of biting.
The species was first described by Carl Linnaeus in 1758 (as Aranea tarantula). It was transferred to the genus Lycosa by Pierre André Latreille in 1806. Charles Athanase Walckenaer in the same 1806 publication described the subspecies narbonensis, which in 1837 he raised to a full species as Lycosa narbonensis. [1] A molecular phylogenetic study in 2013 showed that specimens assigned to this taxon were not genetically different from Lycosa tarantula, [5] so that L. narbonensis is now treated as synonym of L. tarantula. [1]
A once-traditional belief among Apulian peasantry is that a person bitten by one of these spiders must be treated by indulging in a special kind of dancing. The dance, or some version of it, is now known as the tarantella. However, the bites of this spider are not known to cause severe symptoms in humans, much less endanger human life. [6]
The venom of the Lycosa tarantula is not known to be harmful to people [7] , this can also be said for the entire Lycosidae family since it is not one of the families recognized as posing a serious health risk to people [8] . However, L. tarantula has been observed to be harmful to some small vertebrates, so careful handling is important with this species [7] . A broad study of the genus Lycosa found that injecting venom from different spiders in this genus typically only resulted in swelling in guinea pigs that did not last more than 7 days, scabbing in pigs that cleared up in about a week, and slight hemolysis when tested on human red blood cells [9] .
L. tarantula venom is composed mostly of neurotoxins and venom proteins. Their venom shares similarities to other Lycosa spiders, as well as the American Wandering spider, though they are not of the Lycosidae family. While the venom complexity is similar, there are differences in the mass of certain ions and proteins found in male and female venom. When compared to males, over half of these measurements are unique only to the females of the species [7] .
Wolf spiders are members of the family Lycosidae, named for their robust and agile hunting skills and excellent eyesight. They live mostly in solitude, hunt alone, and usually do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow. Wolf spiders resemble nursery web spiders, but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders.
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 recognised 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.
Wasps in the family Pompilidae are commonly called spider wasps, spider-hunting wasps, or pompilid wasps. The family is cosmopolitan, with some 5,000 species in six subfamilies. Nearly all species are solitary, and most capture and paralyze prey, though members of the subfamily Ceropalinae are kleptoparasites of other pompilids, or ectoparasitoids of living spiders.
The Goliath birdeater belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass and body length, and second to the giant huntsman spider by leg span. It is also called the Goliath tarantula or Goliath bird-eating spider; the practice of calling theraphosids "bird-eating" derives from an early 18th-century copper engraving by Maria Sibylla Merian that shows one eating a hummingbird. Despite the spider's name, it rarely preys on birds.
The cobalt blue tarantula or Cyriopagopus lividus is a species of tarantula which is in the family Theraphosidae which is native to Myanmar and over the border into Thailand. It was originally described as Haplopelma lividum.
Heteropoda venatoria is a species of spider in the family Sparassidae, the huntsman spiders. It is native to the tropical regions of the world, and it is present in some subtropical areas as an introduced species. Its common names include giant crab spider, pantropical huntsman spider or cane spider.
Selenocosmia crassipes, synonym Phlogius crassipes, also known as the "Queensland whistling tarantula", "barking spider" or "bird-eating tarantula" is a species of tarantula native to the east coast of Queensland, Australia. The name "whistling tarantula" comes from its ability to produce a hissing noise when provoked, a trait it shares with other Australian theraphosids. This hissing is produced by the spider stridulating a patch of setae associated with its chelicerae. It has also been called the "eastern tarantula". The species name crassipes is Latin for "fat leg" referring to the relatively fat front legs.
Cyriopagopus hainanus is a species of spider in the family Theraphosidae (tarantulas), found in China. It is one of a number of species from China and Vietnam known as "Chinese bird spider". It produces a venom containing numerous compounds capable of blocking neurotransmitters, including neurotoxic peptides called hainantoxins.
Lycosa is a genus of wolf spiders distributed throughout most of the world. Sometimes called the "true tarantula", though not closely related to the spiders most commonly called tarantulas today, Lycosa spp. can be distinguished from common wolf spiders by their relatively large size. This genus includes the European Lycosa tarantula, which was once associated with tarantism, a dubious affliction whose symptoms included shaking, cold sweats, and a high fever, asserted to be curable only by the traditional tarantella dance. No scientific substantiation of that myth is known; the venom of Lycosa spiders is generally not harmful.
Aphonopelma chalcodes, commonly known as the western desert tarantula, desert blonde tarantula, Arizona blonde tarantula or Mexican blonde tarantula, is a species of spider belonging to the family Theraphosidae. It has a limited distribution in the deserts of Arizona and adjacent parts of Mexico but can be very common within this range. The common name "blonde tarantula" refers to the carapace, which is densely covered in pale hairs, and contrasts strongly with the all-dark legs and abdomen. Additionally, these spiders have low toxicity, a long life expectancy, and several offspring.
Tliltocatl albopilosus is a species of tarantula, also known as the curlyhair tarantula. The species' native range is Costa Rica. They are largely terrestrial, opportunistically burrowing spiders.
Tarantulas comprise a group of large and often hairy spiders of the family Theraphosidae. As of December 2023, 1,100 species have been identified, with 166 genera. The term "tarantula" is usually used to describe members of the family Theraphosidae, although many other members of the same infraorder (Mygalomorphae) are commonly referred to as "tarantulas" or "false tarantulas". Some of the more common species have become popular in the exotic pet trade. Many New World species kept as pets have setae known as urticating hairs that can cause irritation to the skin, and in extreme cases, cause damage to the eyes.
Hysterocrates gigas is a member of the tarantula family, Theraphosidae found in Cameroon. It is known as the giant baboon spider, Cameroon red baboon spider, or red baboon tarantula.
Allocosa brasiliensis is a burrowing wolf spider species from southern South America. Long known to science, it remained almost unstudied until its unusual sexual behavior was described in the early 21st century.
Hogna carolinensis, commonly known as the Carolina wolf spider and giant wolf spider, is found across North America. It is the largest of the wolf spiders in North America, typically measuring at 18–20 mm for males and 22–35 mm for females.
Tigrosa helluo, commonly known as the Wetland Giant Wolf Spider, is a species of spider belonging to the family Lycosidae, also known as wolf spiders. T. helluo was formerly known as Hogna helluo before differences between dorsal color patterns, habitat preferences, body structures, etc. were discovered. The species is native to the United States, Canada, and Mexico. It can be found across the eastern half of the United States, primarily in the Northeast and New England, and as far west as Nebraska and Kansas. T. helluo can be found in diverse habitats including woods, marshes, fields, and riparian areas. Typically, members of this species prefer to live in wetter areas as opposed to dry environments. Males tend to live for around a year and females will live for close to two years.
Aphonopelma iodius is a species of spider in the tarantula family Theraphosidae, found in United States. A 1997 paper combined it with three other previously described species into a single species, calling it "A. iodium". However, iodius is a neuter comparative adjective and is the correct form. Aphonopelma smithii has also been synonymized with A. iodius. A. iodius is common in the Mojave Desert to the west of the Colorado River.
Anoteropsis hilaris, commonly referred as the garden wolf spider or the grey wolf spider, is a species of wolf spider that is endemic to New Zealand.
Pardosa pseudoannulata, a member of a group of species referred to as wolf-spiders, is a non-web-building spider belonging to the family Lycosidae. P. pseudoannulata are wandering spiders that track and ambush prey and display sexual cannibalism. They are commonly encountered in farmlands across China and other East Asian countries. Their venom has properties that helps it function as an effective insecticide, and it is, therefore, a crucial pesticide control agent.
