Agelenopsis pennsylvanica
Pennsylvania Grass Spider, Pennsylvania Funnel-web Spider
Agelenopsis pennsylvanica is a funnel-web spider native to the United States, recognized by its characteristic funnel-shaped retreat web. Females are larger than males and exhibit notable sexual cannibalism during mating, a behavior that has been extensively studied in this species. The spider is an ambush predator that relies on vibration detection to capture prey. Its distribution spans at least 21 states, with highest abundance in areas with high humidity and water availability.
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.
Agelenopsis utahana
Utah Funnelweb Spider
Agelenopsis utahana is a species of 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-like webs with a funnel-shaped retreat and hunts prey through rapid pursuit rather than passive entrapment.
Eratigena agrestis
Hobo Spider
Eratigena agrestis, commonly known as the hobo spider, is a funnel-web spider native to Europe that was introduced to the Pacific Northwest of North America in the early 20th century. It constructs characteristic funnel-shaped webs and lies in wait at the narrow end to capture prey. The medical significance of its bite remains poorly understood and debated. Spiderlings emerge in spring, contrasting with the fall emergence of the closely related E. atrica.
Hexurella
dwarf funnel web spiders
Hexurella is a genus of dwarf funnel web spiders (Mygalomorphae, Hexurellidae) comprising some of the smallest mygalomorph spiders in the world. Adults measure 2.5–5 mm in body size. The genus represents a phylogenetically ancient, relictual lineage that diverged from other atypoids approximately 300 million years ago. As of 2026, the genus contains eight species, with four described in a 2023 taxonomic revision. Several species have highly restricted geographic ranges and may warrant conservation attention.
Megahexura fulva
Tawny Dwarf Tarantula
Megahexura fulva is a small mygalomorph spider native to the western United States. It constructs an exposed sheet web with a funnel-shaped retreat in holes and crevices along ravine banks. The species is the sole member of the genus Megahexura, which was formerly placed in Mecicobothriidae but is now recognized in its own family, Megahexuridae. These spiders are among the smallest mygalomorphs, with body lengths typically under 10 mm.
Sosippus janus
Funnel-web Wolf Spider
Sosippus janus is a species of wolf spider in the family Lycosidae, first described by Brady in 1972. It is one of six Sosippus species known from the United States. Unlike most wolf spiders, members of this genus are web-builders, constructing sheet-like webs with funnel-like retreats. The species is found in the southern United States.
Sosippus placidus
Lake Placid Funnel Wolf Spider
Sosippus placidus is a web-building wolf spider in the family Lycosidae, endemic to the United States. Unlike most wolf spiders, which are nomadic hunters, this species constructs thick sheet-like webs with funnel-like retreats. It is described as a habitat specialist compared to its widespread congener Sosippus floridanus. The species is known from relatively few observations (31 records on iNaturalist as of source date), suggesting restricted distribution or specific habitat requirements.
Sosippus texanus
Sosippus texanus is a species of funnel-web wolf spider in the family Lycosidae, distinguished from typical wolf spiders by its web-building behavior. Unlike the nomadic hunting behavior of most lycosids, this species constructs sheet-like webs with funnel-shaped retreats. It is one of six Sosippus species occurring in the United States and has been documented as a host for the mantisfly Mantispa sayi.
Tegenaria domestica
Barn Funnel Weaver, Domestic House Spider
Tegenaria domestica is a funnel-web spider in the family Agelenidae, native to Europe but now distributed nearly worldwide through human introduction. It is one of the smaller species in its genus, with females averaging 7.5–11.5 mm and males 6–9 mm in body length. The species is notable for building characteristic funnel-shaped webs and for recently documented colonial behavior in a unique cave environment in Greece/Albania, where thousands of individuals cooperatively maintained a communal web exceeding 100 square meters.
Wadotes calcaratus
Wadotes calcaratus is a species of funnel-web spider in the family Agelenidae. It was originally described as Coelotes calcaratus by Keyserling in 1887. The species occurs in eastern North America, where it constructs funnel-shaped webs in forested habitats. It has been documented as prey for the spider wasp Priocnemis minorata.
