Multiple Choice

Which characteristic correctly describes Lepidoptera?

Lepidoptera are defined by their siphoning mouthparts and their life cycle through complete metamorphosis. The adult moths and butterflies have a long, coiled proboscis formed from the maxillary galeae that specializes in sipping nectar, rather than chewing. They also undergo holometabolism, meaning they pass through four distinct life stages: egg, larva (caterpillar), pupa (chrysalis or cocoon), and adult. This combination—siphoning mouthparts in the adult and a four-stage metamorphosis—is what sets Lepidoptera apart from groups with chewing mouthparts or with incomplete metamorphosis.
