In a Tokyo greenhouse, researcher Ko Mochizuki observed an unusual phenomenon. Flies swarmed around the delicate flowers of the Vincetoxicum nakaianum plant species, which offers no nectar or bright colors.
Instead, the blooms release a chemical signal that smells like an injured ant, a potential food source for the flies. This unique strategy tricks pollinators into visiting the flowers.
The plant mimics the smell of ants under attack to attract pollinators.
The Vincetoxicum nakaianum, a flowering dogbane species native to Japan, has evolved this ingenious deception strategy to ensure its pollination.
