<p>When disturbed, the spider might first vibrate the web to try to make its body look bigger, but if that fails to deter a predator she will drop to the ground and hide (Faulkner 1999). Adults may be captured by wasps such as the Blue Mud Dauber, <span class="taxon"><em>Chalybion californicum</em></span> (Landes et al. 1987). They are also eaten by birds, lizards, and shrews.</p>  <p>Overwintering egg cases protect spiderlings from predation. Suspending the cocoon from the web is particularly effective against ant predation. The vast majority, however, are eventually damaged by birds. Cocoons wall layers provide barriers against burrowing larvae of insect predators and ovipositors of parasitic insects, but <span class="taxon">Ichneumonidae</span> wasps such as <span class="taxon">Tromatopia rufopectus</span> and <span class="taxon">Chloropidae</span> flies such as <span class="taxon"><em>Pseudogaurax signatus</em></span> lay their eggs in <span class="taxon"><em>Argiope aurantia</em></span> egg cases. In fact, one study found that in addition to <span class="taxon"><em>Argiope aurantia</em></span>, nineteen species of insects and eleven species of spiders emerged from <span class="taxon"><em>Argiope aurantia</em></span> egg cases.
