Coras aerialis is a species of funnel weaver spider in the family Agelenidae, first described by Muma in 1946. It is found in the United States, with records from Vermont and other eastern states. The species belongs to a genus of forest-dwelling spiders that construct funnel-shaped webs with multiple retreats, often in elevated positions or crevices.
Dictyonia
Dictyonia n-sp is an undescribed species of sheetweb weaver spider (family Linyphiidae) documented from Door County, Wisconsin, USA. It was recorded during a nocturnal survey of building exteriors in a forested lakeshore habitat. As a member of Linyphiidae, it constructs a flat, sheet-like web and hunts by hanging inverted on the web surface.
Evarcha hoyi
Hoy's Jumping Spider
Evarcha hoyi is a species of jumping spider in the family Salticidae, commonly known as Hoy's Jumping Spider. It is native to North America and has been documented across the United States and Canada. As a member of Salticidae, it possesses the characteristic large anterior median eyes that provide acute vision for hunting. The species is primarily diurnal but has been observed sheltering on building exteriors at night.
Xylesthia
Xylesthia is a genus of wall spiders in the family Oecobiidae, a group of small arachnids known for constructing flat, tangled webs on vertical surfaces such as walls, rocks, and tree trunks. These spiders are characterized by their compact bodies, relatively long legs, and distinctive spinneret arrangement. The genus is poorly documented in North American faunal surveys, with most species described from other regions. The 'n-sp' designation indicates an undescribed or unidentified species within the genus.
