Which insects have siphoning mouthparts?

• A. Butterflies and moths
• B. Beetles and beetle larvae
• C. Bees and wasps
• D. Ants and termites

Answer: (A)

Siphoning mouthparts are long, tube-like feeding structures formed by the maxillae and labium that uncoil into a slim proboscis used to suck nectar from flowers. This adaptation is characteristic of butterflies and moths, which feed primarily on nectar by extending their proboscis into flower corollas. Other insects rely on different mouthparts—beetles have chewing mandibles, while ants and termites also use chewing mouthparts, and some bees use chewing or chewing-lapping mouthparts—so they don’t possess the specialized nectar-sipping tube. Therefore, butterflies and moths are the insects with siphoning mouthparts.
