Argiope aemula is species of giant conspicuous signature spiders of the genus Argiope seen in tropical and subtropical grasslands. Signature spiders get their name from the zigzag design embozzed on the web and is called stabilimentum. They are believed to serve camouflage function. They show extreme sexual dimorphism and males are only 10% of the female in size and as a result become victim of sexual cannibalism. If the males survive the first copulation, then they almost always die during the second attempt. However, further studies have shown that male invariably dies after second copulation as a form of programmed suicide.
