 The dead horse arum manipulates the heat to release an odor that lures the flies to the structure of the appendix of the flower to begin pollination.This odor is a strong, putrid smell, its composition has a similarity to a real carcass, which flies are not able to distinguish from a real carcass.Blow flies, such as the common green bottle fly ("Lucilia sericata"), find the smell and the flesh-colored hairy inflorescence of the plant irresistible, such that large numbers of flies are attracted into the plant.
