What factor strongly dictates the required microclimate where *D. crocata* populations thrive?
Answer
The high humidity required by its isopod food source
The behavioral ecology and habitat selection of the woodlouse spider are entirely dictated by the environmental requirements of its specialized prey, the woodlouse. Since isopods are terrestrial crustaceans that require high humidity to breathe and move effectively, they are found in damp, dark locations like under logs or leaf litter. Consequently, *D. crocata* must also inhabit these same high-moisture microhabitats to remain close to its food supply. This tight ecological coupling means the predator's physiological need to avoid desiccation is managed indirectly by strictly following the moisture needs of its specific, armored prey.
