Butterflies taste with their feet.
If you already knew everything about butterflies up to this point, this information may come as a surprise. However, from the perspective of the butterfly, it isn't all that unusual. A butterfly's everyday duties include eating and mating, both of which necessitate landing, even if only temporarily. When food is a priority, those taste receptors assist the butterfly in locating the appropriate plants and vital nutrients for survival. Many people wonder what it means when a butterfly lands on them, but the truth is that it is most likely just hungry.
