Spiders, one of the top invertebrate predators in the terrestrial ecosystems are an ideal system to study ecological patterns and processes. Their hidden, but fascinating lives is full of drama: they are voracious predators, but get eaten by their own kind; they are also masters of trickery. In this talk, I will narrate two spider stories. One is of deception in the spider world: how ant mimicking spiders doubly deceive both visual predators such as jumping spiders and chemical predators such as mud-dauber wasps. Second story is about cooperation in hunting and web-building in social spiders. I will specifically talk about some recent work on how group size and hunger can influence the web architecture of social spiders.
