Key Concept: Hypermetamorphosis is an exaggerated form of complete metamorphosis.
Why it's correct: Insects like blister beetles (Meloidae) pass through several larval instars that look strikingly different from each other — an active triungulin first, then grub-like sedentary stages — making it complete metamorphosis with DISSIMILAR larval stages.
Why others fail: Ordinary complete metamorphosis has similar-looking larval stages; incomplete metamorphosis and no-metamorphosis development are entirely different categories, not variants of this term.
