Butterflies taste with their feet. Their taste sensors are located in the feet, and by standing on their food, they can taste it!
All butterflies have six legs and feet. In some species such as the monarch, the front pair of legs remains tucked up under the body most of the time, and are difficult to see. Pollen gets attached to the legs of the Butterfly and is carried from plant to plant, assisting in fertilization and the propagation of new seeds and plants.
