Burrowing Wolf Spiders
Geolycosa is a genus of burrowing wolf spiders (family Lycosidae) established by Montgomery in 1904. These spiders are characterized by their obligate burrowing lifestyle, constructing deep cylindrical burrows in sandy or loose soils. Some species build distinctive turrets around burrow openings using sticks and debris. The genus includes approximately 70 species distributed across North America, with some species extending into the Levant. Geolycosa species are medium to large spiders with morphological adaptations for digging, including enlarged chelicerae and stout anterior legs.
