Which Lepidoptera has complete metamorphosis and sucking mouthparts and is commonly a pest on crops as caterpillars?

Explanation:
Lepidoptera undergo complete metamorphosis, and adults typically have sucking mouthparts (a long siphoning proboscis) used to drink nectar, while the larval stage is usually the feeding, crop-damaging form. The best match here is the moth whose caterpillars are well known crop pests; the adult moth has sucking mouthparts, and the pest problem comes from the caterpillars chewing on crops. The Viceroy Butterfly is also a Lepidopteran with a sucking mouthpart as an adult, but its larvae feed on willows and poplars rather than crops, so it isn’t a common crop pest. The other two options are not Lepidoptera at all.
