Joro spider males are smaller than females

Q: Why do Joro Spider webs have a smaller second spider that is not as colorful as the larger spider?

A: That is the dude spider. He is keeping slightly out of reach, waiting for a chance to have sex. Interestingly, there is a scientific reason he is smaller. Scientists have shown that his small size allows him to travel further by ballooning, using a thread of silk to catch a breeze and move between webs and potential mates. On the other hand, the female spider’s larger size allows her to produce more eggs and offspring. Nature is fascinating!
