Which consequence results when pulses of ecdysone cease during dragonfly larval development?

💡 Explanation

Molting arrest happens because reduced ecdysone prevents transcription via ecdysone receptors, thus the genes for subsequent molts or metamorphosis are not activated. Therefore, the larva remains at its current instar, rather than progressing to the next developmental stage triggered by hormones.
