Schizocosa is a genus of wolf spiders (family Lycosidae) containing around 60 species, distributed in North and South America, Africa, and East and Southeast Asia.
Wolf spiders are members of the family Lycosidae. They are robust and agile hunters with excellent eyesight. They live mostly in solitude, hunt alone, and 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.
Nursery web spiders (Pisauridae) is a family of araneomorph spiders first described by Eugène Simon in 1890. They resemble wolf spiders (Lycosidae) except for several key differences. Wolf spiders have two very prominent eyes in addition to the other six, while a nursery web spider's eyes are all about the same size. Additionally, female nursery web spiders carry their egg sacs with their jaws and pedipalps instead of attaching them to their spinnerets as wolf spiders do. When the eggs are about to hatch, a female spider builds a nursery "tent", places her egg sac inside, and stands guard outside, hence the family's common name. Like the wolf spiders, however, the nursery web spiders are roaming hunters that don't use webs for catching prey.
Zoropsidae, also known as false wolf spiders for their physical similarity to wolf spiders, is a family of cribellate araneomorph spiders first described by Philipp Bertkau in 1882. They can be distinguished from wolf spiders by their two rows of eyes that are more equal in size than those of Lycosidae.
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.
The spider genus Sosippus is, with other genera in the subfamily Hippasinae, unique among the spiders in the family Lycosidae in producing a large funnel-web resembling that of the Agelenidae. The posterior spinnerets are more elongate than in other wolf spiders.
Nukuhiva is a genus of spiders with a single species, Nukuhiva adamsoni, that occurs only on the Marquesas Islands in French Polynesia. It is in the wolf spider family, Lycosidae. It has been found on Nuku Hiva and on Ua Huka, a smaller island about 25 km (16 mi) to the east.
The Artoriinae are a subfamily of wolf spiders. The monophyly of the subfamily has been confirmed in a molecular phylogenetic study, although the relationships among the subfamilies was shown to be less certain.
Dolomedes scriptus is a fishing spider found in the United States and Canada, known as the striped fishing spider. Female spiders can grow to be over 6 cm in legspan. The spider is a pale brown colour with lighter stripes around its legs and a stripe down each side of the body. It is similar to D. tenebrosus.
Sexual selection in spiders shows how sexual selection explains the evolution of phenotypic traits in spiders. Male spiders have many complex courtship rituals and have to avoid being eaten by the females, with the males of most species survive a few matings, and having short life spans.
Trebacosa is a genus of wolf spiders first described by Dondale & Redner in 1981.
Tigrosa helluo 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.
Melecosa is a genus of spiders in the family Lycosidae. Its lone species is found in Kazakhstan, Kyrgyzstan, and China.
Schizocosa saltatrix is a species of wolf spider in the family Lycosidae. It is found in North America.
Schizocosa retrorsa is a species of wolf spider in the family Lycosidae. It is found in the United States and Mexico.
Schizocosa bilineata is a species of wolf spider in the family Lycosidae. It is found in the United States and Canada.
Schizocosa crassipes is a species of wolf spider in the family Lycosidae. It is found in the United States.
Schizocosa ocreata is a species of wolf spider in the family Lycosidae that is found in North America. The Schizocosa ocreata is a spider that is most commonly known as the “brush-legged wolf spider” because of their distinct dark-colored fur-like coverings around their legs. The S. ocreata are commonly found in North American states, usually in the middle and eastern United States.
Schizocosa mccooki is a species of wolf spider in the family Lycosidae. It is found in North America.
Schizocosa crassipalpata is a species of wolf spider in the family Lycosidae. It is found in the United States and Canada.
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.
