Which endocrine disruption causes incomplete butterfly wing formation during pupal metamorphosis?

💡 Explanation

When ecdysone receptors are activated prematurely by endocrine disruptors circulating precocenes, the cellular differentiation programs for wing scales accelerate anomalously disrupting proper vein formation because gradients cannot accurately map the wing leading to asymmetric results. Therefore premature ecdysone triggers anomalous scaling patterns rather than delayed degradation, factor changes, or chitin inhibition under regular hormonal dynamics.
