A wide variety of insects, mammals, birds, reptiles and amphibians prey on the wolf spider; specific examples include coyotes, owls and certain species of wasps. Wolf spiders are also cannibalistic. The wolf spider belongs to the family Lycosidae, which is ancient Greek for "wolf."
Wolf spiders sport a dramatic range of body sizes, with the smallest members measuring 0.04 of an inch and the largest spanning 1.38 inches in length excluding legs. As active hunters, wolf spiders use their speed, agility and power to overwhelm prey as opposed to using silk as is the case with most other spiders. The female wolf spider is unique within the arachnid world for her maternal behavior as she not only carries her egg sack but also tends to her young when they hatch.
