Residing predominantly among leaf litter and under loose bark in forested regions, white-spotted swift spider is an elusive predator with a diet primarily consisting of small arthropods. Its effective hunting strategy involves actively seeking prey rather than constructing webs. As a nocturnal hunter, white-spotted swift spider uses the cover of darkness to ambush its unsuspecting prey with precision, which is facilitated by their agile movements and keen eyesight. Juveniles share this predatory behavior, honing their skills as they mature.

Orange-legged swift spiders are mostly black in appearance, with white spots along most of the body and orange front legs. They are typically 6 - 7 mm in length.

Residing primarily in forested habitats, black corinnomma is a skilled nocturnal hunter that relies on its agility rather than webs to capture prey. It exhibits sexual dimorphism, with females showcasing a more robust physique. As a juvenile, black corinnomma consumes small insects, whereas adults can tackle larger invertebrates, reflecting their opportunistic feeding habits.

The animal belongs to the genus Castianeira. The scientific name of the species was first validly published in 1841 by Carl Ludwig Koch.

Adorned with a vivid dorsal pattern that echoes a resemblance to aggressive hymenopterans, twobanded antmimic casts a deceptive silhouette in its habitat. The artful imitation confers a visual deterrent against potential predators, anchoring its survival strategy in mimicry. Though the juvenile twobanded antmimic is known for a diet heavy in soft-bodied arthropods, adults often shift to larger, more robust prey, showcasing a refined predatory versatility throughout their lifecycle.

Castianeira thalia is distinguished by its stealth and precision as a predatory arachnid, demonstrating a preference for stationary hunting rather than web-building to ambush prey. It exhibits varying coloration that aids in camouflage within its native habitats. These arachnids undergo significant transformation from spiderling to maturity, with diet and behavior adapting to their developmental stages.

Castianeira longipalpa is a species of true spider in the family Corinnidae. It is found in the United States as well as Canada. It is a type of ant-mimic sac spider, and has most often been observed along the east coast of North America.

Castianeira descripta, the redspotted antmimic, is a species of true spider in the family Corinnidae. It is found in the United States and Canada.
