What dispersal method is employed by juvenile *Argiope aurantia* that adults cannot use?
Answer
Ballooning
The primary method of dispersal utilized by juvenile *Argiope aurantia* is ballooning. This technique involves the young spiders releasing strands of silk into the air, which catch the wind, allowing the spider to float away to new locations. This method is exclusive to the immature stages because, once the spiders mature into adults, particularly the bulky females, they become too heavy to utilize the wind for transportation in this manner. Adults remain stationary in their chosen habitat, relying on their large webs to secure the necessary high-protein diet.
