How Does The Butterfly Proboscis Work?

A butterfly uses its proboscis like a straw to drink nectar from flowers.

Imagine you're at a juice bar, and instead of using your hands to grab the cup, you have a tiny, bendy tube that you can stick into the juice, and then just sip it through. That’s what a butterfly's proboscis does! It’s like a long, curly straw made of two tubes that come together at the tip.

When a butterfly isn’t using its proboscis, it folds it up neatly inside its head, kind of like how you can roll up your socks and tuck them into your shoes. When it needs to drink nectar, it unfolds the proboscis and sticks it into a flower.

Once the straw is in the flower, the butterfly sips the sweet liquid through the proboscis, just like you sip juice from a straw. The liquid goes all the way up to its mouth, and then into its body, giving it energy to fly and flutter around!
