20-Hydroxyecdysone (ecdysterone or 20E) is a naturally occurring ecdysteroid hormone which controls the ecdysis (moulting) and metamorphosis of arthropods. It is therefore one of the most common moulting hormones in insects crabs etc. It is also a phytoecdysteroid produced by various plants including Cyanotis vaga where its purpose is presumably to disrupt the development and reproduction of insect pests. In arthropods 20-hydroxyecdysone acts through the ecdysone receptor.
