Call it odiferous mimicry. Many plants, like certain foul-smelling species of the notorious genus amorphophallus (literally, "misshapen penis"), are "carrion flowers"--so called because they mimic the stench of rotting flesh to attract insects.

In another plant group, the descriptively named tiny yellow skunk cabbage is also a carrion plant. It's seen here covered in beetles, which are pollinating it.
