What's the apparent evolutionary purpose for developing caffeine?

Same as nicotine. It keeps insects away

Iirc it slows down a type of caterpillars who eat the leaves and makes them smell yummier to predators but i don't remember where i saw it

It's toxic to insects, so it's a natural pesticide iirc
