Head

There are four main structures included in the head. These are the eyes, antennae, palpi and proboscis. Their eyes contain thousands of tiny lenses and are huge compared to the rest of the body. The antennae sense molecules in the air and provide a sense of smell. The proboscis is like a straw and butterflies use it to suck up nectar and water for energy. When it is not being used they are able to curl up the proboscis.
