Nephila pilipes display sexual dimorphism, the presence of distinct difference between the males and females of a species.
In Nephila pilipes, female spiders are much larger than their male counterparts, and males can be 4–10 times smaller than the females.

Sexual dimorphism appears to be a shared feature among Nephila pilipes spiders of different populations, as examinations of populations in Southeast Asia, Australia, and Papua New Guinea show similar patterns of size dimorphism.
Two major hypotheses have been suggested to explain this sexual selection and they are female gigantism and male dwarfism.
