FlipFact of the Day: Butterflies taste with their feet.
Butterflies possess a tube-like feeding structure called a proboscis, which enables them to feed upon nectar or juices. However, while the proboscis may look like the butterfly equivalent of a tongue, it actually does not have any taste sensors.
Instead, a butterfly’s taste sensors are located underneath its feet, allowing it to “taste” whether a leaf is suitable for laying eggs on (as it will become food for the butterfly’s caterpillars once the eggs hatch).
