"wolf spider" の定義と意味

What is a "wolf spider"?

A wolf spider is a solitary and predatory arachnid belonging to the family Lycosidae. It is known for its agile hunting behavior and keen eyesight. Wolf spiders have a robust body with eight long legs and usually a dark-colored, hairy appearance. They are named for their hunting style, which resembles that of a wolf. Unlike many other spiders, wolf spiders do not spin webs to catch their prey. Instead, they actively hunt and pounce on their victims. Wolf spiders are found in various habitats worldwide, including grasslands, forests, and even urban areas. They are capable of producing silk, which they use for creating retreats or egg sacs. Although wolf spiders can deliver venomous bites, they typically pose little threat to humans unless provoked or handled. These spiders play a vital role in controlling insect populations and are considered beneficial in many ecosystems.
