The insect known for tasting with its legs is the butterfly. Butterflies have taste sensors on various parts of their bodies, including their legs. These sensors, called chemoreceptors, allow them to taste or sense certain chemical cues in their environment, aiding in locating food sources and potential mates.
The tarsi, which are the last segments of a butterfly's legs, contain gustatory receptors, enabling them to taste or assess the chemical composition of surfaces they come into contact with. By standing on a surface, such as a leaf or flower, the butterfly uses its tarsi to assess the suitability of the surface for laying eggs or feeding on nectar.
This unique ability to taste with their legs helps butterflies identify suitable food sources and breeding sites while navigating their environment.
