What function is attributed to the vivid yellow or gold bands on the female *A. aurantia* abdomen?
Answer
Aposematic function
The high-contrast patterning of vivid yellow or gold against a deep black background on the adult female abdomen serves an aposematic function. This type of coloration acts as a warning signal to potential predators, suggesting that the spider is distasteful or dangerous, thereby discouraging attack. While the bright color might attract insect prey, who could mistake the spider for a flower, its primary defensive role seems geared toward deterring other animals, such as birds, from damaging the energy-intensive web structure.
