What indoor feature functions similarly to an outdoor structural crease for a yellow sac spider sac?
Answer
Ceiling and Wall Corners
Yellow sac spiders seek out structurally complex areas indoors that replicate the secure, multi-attachment points found outdoors, such as under bark or dense foliage. The intersection where two surfaces meet, specifically ceiling and wall corners, offers a ready-made crease. This three-dimensional structure provides the necessary support and feeling of security for the spider to spin its small silken sac, making it a highly preferred hiding spot over flat, open surfaces.
