Which process limits the ability of a lepidopteran larva to regenerate a lost limb during molting?

💡 Explanation

During larva molting, regeneration is limited by the systemic balance of ecdysone (molting hormone) and juvenile hormone; high juvenile hormone maintains the larval state, indirectly inhibiting appendage regeneration by suppressing morphogenetic pathways active in imaginal discs through systemic hormone inhibition. Therefore limited regeneration results, rather than energetic, diffusion or resource constraints which involve different metabolic and environmental limits.
