Suetsugu Gnat Flower (IMAGE) Kobe University Caption The flower of Arisaema thunbergii uses a musky odor to lure fungus gnats that usually feed and lay their eggs on mushrooms into their cup-shaped flowers. The insects can escape from the male flowers, but only after tribulations that will result in them being covered in pollen. However, there is no escape from the female flowers. Once they enter these, the involuntary pollen carriers struggle to find an exit, which ensures that they will pollinate the flower, but they can't get a hold on the waxy interior and perish.
