Butterflies are some of the most beautiful insects in the world. However, what interests the scientists most is not their fascinating looks, but how they sense the nature. They use their senses of sight, touch, hearing, smell, and taste to find food, lay eggs in good places, and avoid hungry enemies.
Butterflies have large compound eyes. This allows them to see in all directions without turning their heads. Like most insects, butterflies are very nearsighted. They are more likely to notice a sea of flowers than a single plant. Butterflies do not “see” colors such as red, green, and yellow. They are color blind. But they can sense sunlight, which tells them the direction that the sun is shining. The light presented on many flowers guides butterflies to honey.
How do butterflies smell? Butterflies have a very well-developed sense of smell, but it is not in their noses, since they don't have one. Sense organs* are in their feet, and many other parts of the body. They can help butterflies find their favorite flower honey food.
Do butterflies use their mouths to taste the food they find? Not really. Butterflies’ feet have sense organs that can taste the sugar in flower honey. They let the butterflies know if there is something tasty. To lay their eggs, some female butterflies carefully choose plants by tasting to find proper places. They feed their babies using a long tube*, and they get all their food from this tube as well.
Butterflies don't have ears. Instead, they “hear” sounds through their wings by sensing changes in sound vibrations*. Sensory hairs are all over butterflies’ body. The hairs are very helpful by letting them feel the environment. For example, the hairs give butterflies information about the wind when they’re flying.
Butterflies may have senses we don't even know about yet, because their body is very different from ours. Therefore, it is difficult to understand when we use our own human senses to study it.
