Which Lepidoptera species has complete metamorphosis and sucking mouthparts and is a butterfly named in its common name?
Correct Answer:
Viceroy Butterfly
Explanation:
Lepidoptera, which includes butterflies and moths, all go through a four-stage life cycle (egg, larva, pupa, adult) and typically have mouthparts adapted for sucking nectar with a long proboscis. The Viceroy Butterfly fits best because it is a true butterfly, so its common name includes the word butterfly, and as an adult it has the characteristic siphoning mouthparts used to sip nectar. The other insects listed are not Lepidoptera and do not share these features: a tiger beetle is a beetle with chewing mouthparts; velvet ant is actually a wasp; walking stick is a stick insect.
