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. 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. As of , more than species in this genus have been described.

There are many species of wolf spiders, ranging in size. Most having variegated patterns in brown and yellow, grey, black and white. Often the patterns include radiating lines on the carapace and scroll-like patterns on the abdomen.
Their underside is light grey, cream or black, salmon pink, with black or white markings superimposed. The sides of their jaws may have a small raised orange spot. Wolf spiders have eight eyes in three rows. Habitat and Distribution. Wolf spiders are found in habitats ranging from the arid interior, alpine terrain to coastal zones. Some species are also common in suburban gardens.
Many wolf spiders have wide distributions, aided by their ability to disperse aerially as spiderlings. Many also occur in niches such as stream-side gravel beds, montane herb-fields or coastal sand-dunes. Wolf spiders eats crickets, other spiders, ants, grasshoppers and many other types of small invertebrates. Larger species will also occasionally take small lizards and frogs. They are typically nocturnal hunters. Most wolf spiders are wanderers however some make temporary retreats in vegetation and others build burrows, either with or without a trapdoor.
Arid zone species build turrets to deflect floodwaters during rainy periods, while others use pebbles to plug their burrows. In woodlands, twigs may be used to form a palisade around the top of the burrow. Burrows of the Grey Wolf Spider Lycosa simsoni have a circular trap door that is often left open when the spider is out hunting.
The shape and materials used to form burrows and trapdoors may help to distinguish similar-looking species. Males seek the females outside of their burrows aided by the females scent trail. They then perform a courtship ritual often involving complex leg and palp signalling to the female. The female constructs a white papery silk egg sac, shaped like a ball — she then carries the egg attached to her spinnerets. When the spiderlings hatch, the females carried them on her back until they are ready to disperse.
Such a high degree of parental care is relatively unusual among spiders. Some even take refuge in ones shoes on the verandah, so always make sure you check inside shoes! Your Message. Name required.
