Help in finding the name of a plant with yellow spots on its leaves as a survival mechanism?

Hi! I'm trying to find the name of a plant that developed yellow spots on its leaves as a protection against moth predators. I watched a documentary on adaptation and evolution a very long time ago and it showed a plant that exhibits yellow spots on its leaves which resemble the yellow eggs of a certain moth. These moths lay their eggs on the leaves of this plant and when the caterpillars are born they feed on the plant. If there are already enough eggs on the leaves however, the moth will look for another plant to lay its eggs on so its offspring have enough food. So somehow this plant species figured this out and made its leaves have yellow spots so as to diminish the chance of moths laying their eggs on its leaves and caterpillars eating them away. I can't find the name of this plant though and don't remember what the documentary was called. Do any of you know this plant or remember this documentary?? I remember the documentary's main focus was about how adaptation and evolution gave way to the great diversity of life that the planet exhibits today, and I remembered it focused on fish coloration for a bit (I think). Any help is appreciated! Thanks :)

Passion flowers (Passiflora species) adapted structures that mimic Heliconius butterfly eggs. The plant population was selected to retain those with egg mimics that deter females from laying eggs near previously laid eggs.
