Hello, I'm an expert in the field of entomology, which is the scientific study of insects. When it comes to the anatomy of butterflies, they do possess a mouthpart structure, but it's quite different from what you might think of as a "mouth" in mammals or humans.

Butterflies have a proboscis, which is a long, tubular, and flexible mouthpart that they use to feed on nectar from flowers. The proboscis is made up of two maxillary lobes that are fused together, and it can be coiled up when not in use, allowing the butterfly to uncoil and extend it into a flower to reach the nectar.

So, to answer your question: Yes, butterflies do have a mouthpart, but it's not a mouth as we typically understand it. Instead, they have a specialized feeding structure known as a proboscis.
