Which developmental outcome from molting disruption impedes butterfly eclosion?

💡 Explanation

Incomplete cuticle sclerotization prevents the pupal exoskeleton from properly hardening due to failure of the tanning process; without proper hardening the adult cannot emerge because the pupal case is too soft, therefore preventing eclosion, rather than other endocrine signalling issues.
