What visible behavioral trait links spiders to the *Cheiracanthium* genus?

Answer

Constructing small, silken retreats during the day

The most significant and visible behavioral trait linking spiders to the *Cheiracanthium* genus is their habit of constructing and occupying small, silken retreats, often described as sacs. These spiders are active nocturnal hunters and wanderers, meaning the silk sac is essential for survival during the day, providing a secure location to rest while minimizing exposure to potential predators or environmental risks such as desiccation. This contrasts sharply with spiders that rely on fixed, permanent webs to capture prey.
