Butterflies Taste With Their Feet

Butterflies use sensors on their feet to ‘taste’ leaves and find the right plants for their eggs.

Next time you see a butterfly land on a leaf, it might be doing more than resting—it’s tasting it. Special sensors on their feet let them detect chemicals in plants to find the best place to lay eggs.

That means butterflies literally taste with their feet—a strange but handy talent in the world of insects.
