What are the primary prey items that drove the evolutionary specialization of the woodlouse spider?
Answer
Terrestrial isopods (pill bugs or sowbugs)
The defining evolutionary success of *Dysdera crocata* is intrinsically linked to its diet, which centers almost exclusively on terrestrial isopods, commonly known as woodlice, pill bugs, or sowbugs. These prey items are difficult for many predators to handle because they possess tough, segmented exoskeletons that function as substantial physical armor. The spider's entire morphology, particularly its massive chelicerae, evolved specifically to overcome this defense, representing a classic case of evolutionary adaptation focusing on exploiting a specific, highly protected resource abundant in damp environments.
