Which tiny insect pollinates most cacao flowers?

Ceratopogonid midges pollinate most cacao flowers, making these tiny biting insects essential to chocolate production.

Cacao flowers are small, complicated, and difficult for large pollinators to enter. Midges in the family Ceratopogonidae can move among the flower’s structures and transfer pollen. Natural cacao pollination therefore depends heavily on suitable humid forest conditions and the presence of these insects.

A cacao tree can produce many flowers but relatively few mature pods. Pollination is only the first step: the fertilized flower must develop into a pod, and the seeds inside must later be fermented, dried, roasted, and processed into chocolate.

A common misconception is that honeybees are cacao’s principal pollinators because they pollinate many familiar crops. Cacao differs from those crops. Commercial plantations may attempt hand pollination, but maintaining habitat for natural pollinators remains important for healthy cacao ecosystems.
