Trap pollinators

The western Mediterranean is home to a rather sinister group of plants which exploit flies to bring about pollination. Birthworts (Aristolochia) and members of the Arum family (Araceae) attract insects with the false promise of food, rotting meat to be precise, with their hairy, foul-smelling blooms which resemble carrion. Insects are imprisoned in chambers and showered in pollen before they are released to serve their pollination services again on another flower elsewhere, and thus bring about fertilisation.
