Agelenopsis aperta
Desert Grass Spider, Funnel-web Spider
Agelenopsis aperta, commonly known as the desert grass spider, is a medium-sized funnel-web weaver native to arid regions of the southwestern United States and northwestern Mexico. It constructs characteristic non-sticky funnel-shaped webs in crevices and vegetation, where it waits to ambush prey. The species exhibits notable territorial behavior and complex courtship rituals involving abdominal swaying and pheromone release that induces a temporary cataplectic state in females.
Agelenopsis oregonensis
Agelenopsis oregonensis is a funnel-web spider in the family Agelenidae. It is found in the United States and Canada, with records from Alberta and British Columbia. Like other members of its genus, it constructs sheet webs with a funnel-shaped retreat. The species was described by Chamberlin and Ivie in 1935.
Agelenopsis spatula
funnel weaver spider
Agelenopsis spatula is a species of funnel weaver spider in the family Agelenidae, first described in 1935 by Ralph Vary Chamberlin and Wilton Ivie. It is known only from the United States. As a member of the genus Agelenopsis, it shares the characteristic funnel-web building behavior and elongated spinnerets typical of this group.
Calilena
funnel weavers
Calilena is a genus of North American funnel-web spiders in the family Agelenidae. The genus was established in 1941 and currently contains 21 recognized species distributed primarily across the western and southwestern United States, with some species extending into Mexico. These spiders construct sheet-like webs with funnel-shaped retreats and are characterized by long spinnerets held parallel to each other.
Hololena santana
Hololena santana is a funnel-web weaver spider in the family Agelenidae, described by Chamberlin & Ivie in 1942. The species is found in the United States and belongs to a genus of approximately 30 recognized species restricted to the western third of North America. Like other Hololena, it constructs flat, sheet-like webs with a funnel-shaped retreat and is known to occasionally enter human dwellings.
Hololena tentativa
Hololena tentativa is a funnel-web weaver spider in the family Agelenidae, found in the United States. Like other Hololena species, it constructs flat, sheet-like webs with a funnel-shaped retreat. The genus is restricted to the western third of the U.S. and contains approximately thirty recognized species in need of taxonomic revision.
Tegenaria pagana
Rural Funnel-web Spider, House Funnel-web Spider
Tegenaria pagana is a small funnel-web spider in the family Agelenidae, first described from Greece in 1840. It is a synanthropic species strongly associated with human habitations, earning it the common name 'house funnel-web spider.' The species is native to the Palearctic region from Europe through North Africa to Central Asia, but has been introduced globally and is now established on multiple continents. A 2013 taxonomic revision substantially reduced its synonymy, consolidating several previously recognized species. It has been studied as a comparative model for eye development and troglomorphic evolution in cave-dwelling spiders.
