From Wired:
Found in Central America, the order-defying jumping spider eats nutrient-rich structures called Beltian bodies, which are found on the tips of Acacia trees. Trees produce the bodies to feed ants that defend them, which is a textbook example of what’s called co-evolutionary mutalism, and one that B. kiplingi has evolved to exploit.

This is the world's first known vegetarian spider. The males also take part in parental care, another arachnid rarity.
