A tricky insect-eating plant from Borneo proves that one need not have a brain to outsmart the opposition.

Scientists say the carnivorous plant exploits weather fluctuations to adjust the slipperiness of its pitfall traps in order to capture and dine on batches of ants at a time rather than individual ants.

The research involved a species of the pitcher plant, so named because its leaves form cup-shaped insect traps that look like a pitcher.
