Guides
Geolycosa fatifera
Geolycosa fatifera is a burrowing wolf spider in the family Lycosidae, found in the United States. As a member of the genus Geolycosa, it spends the majority of its life in a deep burrow. The species was first described by Nicholas Marcellus Hentz in 1842. Like other Geolycosa species, it exhibits traits associated with fossorial (burrowing) existence, including stout front legs adapted for digging.
Geolycosa gosoga
Geolycosa gosoga is a species of burrowing wolf spider in the family Lycosidae. It is endemic to the United States, with records from the southwestern and south-central regions including New Mexico and surrounding areas. As a member of the genus Geolycosa, it constructs deep, silk-lined burrows in sandy soils and is primarily nocturnal.
Geolycosa hubbelli
Geolycosa hubbelli is a species of burrowing wolf spider in the family Lycosidae. It is found in the United States and belongs to a genus characterized by deep, silk-lined burrows. Members of this genus are typically associated with sandy or loose soil habitats where they construct vertical burrows with debris-reinforced turrets.
Geolycosa micanopy
Geolycosa micanopy is a burrowing wolf spider species in the family Lycosidae, described by Wallace in 1942. It is known from the United States. As a member of the genus Geolycosa, it constructs deep, silk-lined burrows in sandy substrates. A laboratory study has examined burrow establishment behavior in young individuals of this species in relation to microhabitat conditions and prey availability.
Geolycosa patellonigra
Geolycosa patellonigra is a burrowing wolf spider species in the family Lycosidae, described by Wallace in 1942. It is found in the United States, with records from Florida and potentially other southeastern states. As a member of the genus Geolycosa, it constructs deep silk-lined burrows in sandy soils and exhibits notable ballooning behavior—spiderling aerial dispersal via silk threads—at frequencies higher than typical for wolf spiders. The species shows geographical variation in its seasonal distribution patterns.
Geolycosa rafaelana
Rafaela Burrowing Wolf Spider
Geolycosa rafaelana is a burrowing wolf spider in the family Lycosidae, found in western desert and scrubland habitats of the United States. As a member of the genus Geolycosa, it constructs deep, silk-lined burrows in sandy soils and is primarily nocturnal. The species was described by Chamberlin in 1928 and appears to be associated with arid environments in the southwestern U.S.
Geolycosa riograndae
Geolycosa riograndae is a species of burrowing wolf spider in the family Lycosidae, first described by Wallace in 1942. It belongs to a genus characterized by deep, silk-lined burrows and fossorial habits. The species is known from the United States, with records primarily from the southwestern region including New Mexico. Like other Geolycosa species, it exhibits the elevated cephalothorax and stout digging appendages typical of burrowing wolf spiders.
Geolycosa turricola
turret spider, burrowing wolf spider
Geolycosa turricola is a burrowing wolf spider (family Lycosidae) native to the eastern United States, ranging as far west as Ohio. This species constructs deep, silk-lined burrows in sandy soils, often with a distinctive turret of silk and debris at the entrance. It exhibits an obligate burrowing lifestyle with a two-year life cycle and has been documented showing high frequencies of ballooning behavior—aerial dispersal via silk threads—despite occupying relatively stable sand dune habitats. Spiderlings display subsocial organization with prolonged mutual tolerance within broods, facilitated primarily by chemical communication.
Geolycosa xera
McCrone's burrowing wolf spider
Geolycosa xera, commonly known as McCrone's burrowing wolf spider, is a species of wolf spider in the family Lycosidae. It is endemic to Florida in the United States, where it inhabits scrub habitats in several central Florida counties. The species was described by McCrone in 1963 and comprises two recognized subspecies with restricted distributions.
