Which consequence results insects reaching a critical larval weight?

💡 Explanation

Ecdysone release triggers molting because reaching critical weight enables the prothoracic gland to synthesize more ecdysone. This initiates a cascade toward pupation and metamorphosis, therefore ecdysone increase, rather than diapuase, occur, because synthesis stops late into pupae stage.
