Schizocosa mccooki is a species of wolf spider in the family Lycosidae. They can be found from the west coast to western Lake Erie in western North America, including Canada, the United States, and Mexico. [6] [7] [8] [9]
Schizocosa mccooki is a large wolf spider with the body length ranging between 9.1–15.5 mm (0.36–0.61 in) for males and 9.6–22.7 mm (0.38–0.89 in) for females. [6] The carapace ranges in color from gray to light brown with a pale median band, black lateral bands, and pale submarginal bands that sometimes extend to the margins. [6] [7] [8] The dorsum of the abdomen typically has a demarcated heart mark and dark transverse bars with a series of paired white spots, while the lateral areas are mottled yellow, brown, and black, with a few oblique black lines. [6] [7] [8] The venter ranges in color from reddish-brown to dark orange, but may also have may extensive black areas, particularly under the abdomen. [6] [7] Males and females have similar appearances, with the exception of darker tipped forelegs in females. [10]
S. maxima and S. mccooki are virtually indistinguishable except by size. [6] S. maxima have a body length ranging between 16.1–20.3 mm (0.63–0.80 in) for males and 21–28.4 mm (0.83–1.12 in) for females. [6] [7] Recent phylogenomic work suggests that S. maxima may be a junior synonym of S. mccooki, however formal nomenclatural changes are pending future studies. [9]
S. mccooki are widespread in open habitats such as grasslands, chaparral, the desert, and pinyon pine forests, among others. [7] [8] Some populations of this species have been observed digging burrows. [11] [8]
Wolf spiders are members of the family Lycosidae, so 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.
Homalonychus is a genus of araneomorph spiders, and is the only genus in the family Homalonychidae. It was first described by George Marx in 1891. As of October 2023 it contains only two species: H. selenopoides and H. theologus. They are found in the southern United States and Mexico: H. theologus is mostly found west of the Colorado River, while H. selenopoides is mostly found to the east, with some populations in Death Valley and near Mercury, Nevada.
The Kauaʻi cave wolf spider, also known to local residents as the blind spider, is only known to occur in a few caves in a lava flow with an area of 10.5 km2 (4.1 sq mi) in the Kōloa–Poʻipū region of Kauaʻi, Hawaiian Islands, and only six populations are known to exist. While their nearest surface-dwelling relatives have large eyes, this species has completely lost its eyes. They reach a body length around 20 mm (0.8 in), and are reddish brown and completely harmless to people. Unlike most wolf spiders, it produces only 15 to 30 eggs per clutch. The female carries the egg sac in her mouthparts until the spiderlings hatch.
Dolomedes tenebrosus or dark fishing spider is a fishing spider found in the United States and Canada.
Anisoditha is a genus of pseudoscorpions in the family Chthoniidae. There is at least one described species in Anisoditha, A. curvidigitata.
Ditha is a genus of pseudoscorpions in the family Chthoniidae. There are about 14 described species in Ditha.
Tridenchthonius is a genus of pseudoscorpions in the family Chthoniidae. There are about 16 described species in Tridenchthonius.
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.
Pisaurina mira, also known as the American nursery web spider, due to the web it raises young in, is a species of spider in the family Pisauridae. They are often mistaken for wolf spiders (Lycosidae) due to their physical resemblance. P. mira is distinguished by its unique eye arrangement of two rows.
Ummidia is a genus of mygalomorph spiders in the family Halonoproctidae, and was first described by Tamerlan Thorell in 1875.
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.
Cyriogonus is a genus of African crab spiders that was first described by Eugène Louis Simon in 1886.
Garypus is a genus of pseudoscorpions in the family Garypidae. It was described by German arachnologist Ludwig Carl Christian Koch in 1873. The species are found mainly in tropical and subtropical areas, where they occupy supralittoral and littoral zones in seashore habitats.
Pardosa lapidicina, the stone spider, is a species of wolf spider in the family Lycosidae.
Hogna pseudoceratiola is a species of wolf spider in the genus Hogna of the family Lycosidae. It was described for the first time by H. K. Wallace in 1942.
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.
Schizocosa stridulans is a sibling species of S. ocreata and S. rovneri and is part of the wolf spider family. The name of the genus comes from the epigynum structure being lycosid and having a split T excavation. This spider is well-known for its specific leg ornamentation and courtship rituals and that is how it has been differentiated from its related species. The S. stridulans take systematic steps during its courtship ritual, which involves two independent signals. More specifically, female spiders will leave silk and pheromones to communicate that they are ready to mate.

Allocosa subparva is a species of wolf spider in the family Lycosidae. They are found throughout western North America, as far north as Oregon to Idaho and as far south as Nayarit, Mexico.
