This spider is also known by the name of a peacock spider, because it has a beautiful color, and a round cover like a peacock on the abdomen of a male spider. Like peacocks, the male abdominal cover of this cute species is shaped like a colorful fan and is used to attract the female's attention. While shaking their legs and abdomen, they do a dramatic effect when attracting the attention of the opposite sex.
