ELI5: How is it possible that pattern imitation occurs naturally in nature? To put this into context I was reading about the mirror orchid, a parasitic plant that doesnt produce nectar as a lure to attract bees to pollinate it, to get around this it has a lower petal that looks like a bee trying to mate and that's how it pollinates. RIGHT. SO.

HOW??? I mean it doesnt look EXACTLY like a bee but it is pretty darn close! How does something without eyes or a brain know what its main pollinators look like and imitate them?
