Iridomyrmecin is a defensive chemical, classified as an iridoid, isolated from ants of the genus Iridomyrmex.[1] It has also evolved into a sex pheromone in wasps such as Leptopilina,[2] with host species using the smell of iridomyrmecin as a way of detecting the presence of the parasitoid wasps.[3] Iridomyrmecin is also found in a variety of plants including Actinidia polygama.[4]
