Why does the mature female *D. crocata* reaching up to 15 mm offer an advantage when confronting prey?
Answer
The bulk provides leverage and reach necessary to subdue armored prey
The relatively substantial size achieved by mature females, up to 15 mm in body length, is advantageous in their specialized predatory role. Subduing a pill bug, which can instantly roll into an impenetrable defensive sphere, requires significant physical power and maneuverability. A larger spider possesses the necessary leverage and reach to effectively navigate the prey's defensive posture, ensuring it can maneuver into a position to deliver a decisive bite. This size characteristic likely developed under selective pressure favoring individuals capable of reliably overcoming the physical defense mechanisms of their armored food source.
