About Argiope bruennichi (Scopoli, 1772)
Argiope bruennichi (Scopoli, 1772) displays sexual dimorphism. Adult males of this species have an average body length of around 4.5 mm, while adult females have a body length ranging from 14 to 20 mm. The small body size of males lets them enter a female's web without being detected to mate, which gives them a major fitness advantage.
