Wolf spider is a common name for the spider family Lycosidae, known for hunting prey on the ground rather than catching it in a web.

Context

Wolf spiders belong to the family Lycosidae, a group of ground-dwelling hunters known for their speed and excellent eyesight [2]. Unlike web-building spiders, they actively chase and pounce on prey [3]. With more than 2,300 species across 135 genera, they are widespread, with about 240 species in North America and 50 in Europe [4]. Females carry their egg sacs attached to spinnerets, and after hatching, spiderlings ride on the mother's back [4]. While often mistaken for tarantulas, wolf spiders are not medically significant to humans [4].
