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.
Euryopis californica
Euryopis californica is a small cobweb spider in the family Theridiidae, notable for its highly specialized ant-hunting behavior. Unlike most theridiids that construct tangled webs to capture prey, this species is an active predator that specifically targets harvester ants. It has been documented as a predator of Veromessor pergandei, employing unique hunting tactics to overcome the formidable defenses of these aggressive ants. The species occurs in the United States and Mexico.
Liturgusa
Lichen Mantises, Bark Mantises
Liturgusa is a genus of Neotropical bark mantises comprising more than twenty species. Unlike typical mantises, Liturgusa species are exceptionally fast runners that actively pursue prey rather than ambush it. They inhabit tree trunks and branches, where their flattened bodies and cryptic coloration provide effective camouflage against bark, moss, and lichen. The genus was revised in 2014, revealing substantially greater diversity than previously recognized.
Phidippus ardens
Desert Red Jumping Spider
Phidippus ardens is a species of jumping spider in the family Salticidae. It is found in the western United States and Mexico. Like other members of the genus Phidippus, it possesses enlarged anterior median eyes characteristic of salticids and is an active visual predator.
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.
