What is the primary function of the silk produced by *D. crocata*?
Answer
Lining retreats or creating egg sacs
Unlike many familiar spider families that invest heavily in building complex, ephemeral aerial webs for capturing prey, the woodlouse spider utilizes its silk for structural purposes related to shelter and reproduction. Specifically, the silk is employed primarily for creating a protective tube-like retreat where the spider rests during daylight hours, or for constructing secure egg sacs. This difference highlights a major evolutionary trade-off: energy is conserved by avoiding the constant construction of feeding webs, instead prioritizing the maintenance of a permanent, defended home base located near high-moisture foraging grounds.
