Wolf spiders are common spiders outdoors and are occasionally seen indoors. They are moderate to large-sized spiders. Wolf spiders are found on the ground or under stones in a wide variety of habitats, such as forest floors, grassy meadows and swamps. Some even like to live underground. They commonly hunt during the day or at night when it is warm. Wolf spiders are dark-coloured, usually brownish or greyish, with white markings.
