Walckenaeria directa
dwarf spider
Walckenaeria directa is a species of dwarf spider in the family Linyphiidae, first described by O. Pickard-Cambridge in 1874. The species is known to occur in the United States and Canada. As a member of the sheet-web weavers, it belongs to one of the most diverse spider families, though specific ecological details for this species remain limited.
Walckenaeria exigua
dwarf spider
Walckenaeria exigua is a species of dwarf spider in the family Linyphiidae, first described by Millidge in 1983. It belongs to a genus of small sheet-web weavers characterized by their diminutive size and specialized genital morphology. The species has been documented across much of North America, with confirmed records from both the United States and Canada. Like other members of Linyphiidae, it constructs flat sheet webs with a retreat area, though specific web architecture details for this species remain undocumented.
Walckenaeria occidentalis
Walckenaeria occidentalis is a species of sheet-web weaver spider in the family Linyphiidae, described by Millidge in 1983. The specific epithet 'occidentalis' indicates a western distribution pattern. Like other members of this large family of small spiders, it constructs flat sheet webs with a retreat and associated knockdown threads to capture prey. The genus Walckenaeria contains numerous species, many of which are poorly known and require specialist identification.
Walckenaeria pallida
dwarf spider
Walckenaeria pallida is a species of dwarf spider in the family Linyphiidae, first described by Emerton in 1882. It is a small sheet-web weaver found in North America. The species has been documented in the United States and Canada, with specific records from Manitoba.
Walckenaeria palustris
Walckenaeria palustris is a species of dwarf spider in the family Linyphiidae, described by Millidge in 1983. The specific epithet 'palustris' (Latin for 'of the marsh') suggests association with wetland or marshy habitats. Like other members of the genus Walckenaeria, it is a small-bodied spider with characteristic genitalic structures used for species identification. The species has been recorded in Canada based on available distribution data.
Walckenaeria spiralis
Spiraling Sheet-web Weaver
Walckenaeria spiralis is a dwarf spider species in the family Linyphiidae, first described by Emerton in 1882. It belongs to a large genus of small sheet-web weaving spiders distributed across the Holarctic region. The species is known from scattered records across northern North America and the Russian Far North-East, suggesting a boreal distribution pattern.
Wubana
Wubana is a genus of sheet-web weaving spiders (family Linyphiidae) endemic to the United States. First described by Ralph Vary Chamberlin in 1919, the genus contains seven recognized species as of 2019. These small spiders construct flat, horizontal sheet webs for prey capture. The genus is exclusively North American with no documented occurrences outside the United States.
Wubana atypica
Wubana atypica is a species of sheetweb spider in the family Linyphiidae, first described in 1936. It is distributed across the United States and Canada, with confirmed records from Alberta and British Columbia. As a sheetweb spider, it constructs flat, horizontal webs for prey capture. The species remains poorly documented in scientific literature, with limited information available on its biology and ecology.
Wubana pacifica
Wubana pacifica is a species of sheetweb spider in the family Linyphiidae. It was described by Nathan Banks in 1896. The species is known from the United States. As a member of Linyphiidae, it constructs flat, horizontal sheet webs rather than orb webs.
Zornella
Zornella is a genus of sheet-weaving spiders (family Linyphiidae) established by A. R. Jackson in 1932. The genus contains three described species with a disjunct distribution: two species occur in North America (USA and Canada), while one species ranges across northern Eurasia from northeastern Europe through Russia to Kazakhstan and Mongolia. As linyphiids, members construct horizontal sheet webs with a retreat.
Zornella armata
dwarf spider
Zornella armata is a species of dwarf spider in the family Linyphiidae. It was first described by Nathan Banks in 1906. The species has been recorded in the United States and Canada, with specific occurrence records from Alberta, British Columbia, and Manitoba in Canada.
