Cheiracanthium inclusum
black-footed yellow sac spider, American yellow sac spider, Agrarian Sac Spider
Cheiracanthium inclusum is a small, pale yellow spider native to the Americas, commonly known as the black-footed yellow sac spider or American yellow sac spider. It is an active nocturnal hunter that does not construct webs to capture prey, instead relying on speed and agility to pursue arthropods. The species builds small silk retreats during daylight hours and is frequently encountered both in natural vegetation and human dwellings. Despite historical misconceptions, its bite produces only localized symptoms without necrosis.
Cheiracanthium mildei
Northern Yellow Sac Spider, Long-legged Sac Spider
Cheiracanthium mildei is a medium-sized spider native to Europe and North Africa, introduced to North America and parts of South America. Adults measure 7–10 mm in body length with pale green or tan coloration, darker palpi and chelicerae, and characteristically long front legs up to twice the length of others. It constructs silken retreats rather than capture webs, hunting actively at night. The species is frequently encountered in human dwellings, particularly in northern regions of its introduced range, and has been documented to bite humans with generally mild effects.
Clitemnestra bipunctata
Clitemnestra bipunctata is a small sand wasp in the family Crabronidae, measuring approximately 5-6 millimeters in body length. The species was formerly classified under the genus Ochleroptera, but was merged into Clitemnestra by Bohart in 2000. It is widely distributed across North America and has been recorded from Cuba.
Clubiona abboti
Clubiona abboti is a species of sac spider in the family Clubionidae, found in the United States and Canada. It is a nocturnal hunter that does not construct webs to capture prey. The species was described by L. Koch in 1866 and includes two recognized subspecies: C. a. abboti and C. a. abbotoides.
Clubiona riparia
Riparian Sac Spider
Clubiona riparia is a sac spider species in the family Clubionidae. It is known from a broad geographic range spanning northern Eurasia and North America. The specific epithet 'riparia' refers to its association with riparian habitats. Like other Clubiona species, it constructs silken retreats rather than prey-capture webs and hunts actively.
Drassyllus prosaphes
Drassyllus prosaphes is a species of ground spider in the family Gnaphosidae, first described by Chamberlin in 1936. It belongs to a genus of small to medium-sized nocturnal hunting spiders commonly found in leaf litter and soil habitats. The species occurs in the southwestern United States and Mexico. Like other members of Gnaphosidae, it lacks a permanent web and actively pursues prey.
Gertschosa
Gertschosa is a genus of ground spiders in the family Gnaphosidae, established by Norman I. Platnick and M. U. Shadab in 1981. The genus contains four species distributed across the Caribbean, Central America, and southern North America. Its members are nocturnal hunting spiders that do not construct webs for prey capture.
Haplodrassus signifer
Ensign Ground Hunter
Haplodrassus signifer is a species of ground spider in the family Gnaphosidae. It has a broad distribution spanning North America, Europe, North Africa, Turkey, Israel, the Caucasus, Russia, Central Asia, China, Korea, and Japan. The species is part of a large genus of active hunting spiders that do not build webs to capture prey.
Scotophaeus blackwalli
Mouse Spider
Scotophaeus blackwalli, commonly called the mouse spider, is a ground-dwelling spider in the family Gnaphosidae. It is native to Europe, the Caucasus, Turkey, and Iran, and has been introduced to North America, Peru, and Hawaii. The species is nocturnal and does not build webs for prey capture, instead hunting actively or scavenging opportunistically. It is frequently found in and around human dwellings, particularly in Britain during autumn.
Zelotes fratris
Zelotes fratris is a ground spider in the family Gnaphosidae, described by Chamberlin in 1920. It has a transcontinental distribution spanning Russia (Middle Siberia to Far East) and North America. The species belongs to a large genus of active hunting spiders that do not build webs to capture prey. Specific ecological details for this species remain limited in the literature.
Zora pumila
Zora pumila is a species of prowling spider in the family Miturgidae. The species was first described by Nicholas Marcellus Hentz in 1850. It is known from the United States, though specific details regarding its biology and ecology remain poorly documented in the scientific literature. As a member of Miturgidae, it belongs to a family of wandering spiders that actively hunt prey rather than building webs to capture them.
