Figs rely on a highly specialized relationship with wasps that has evolved over millions of years. While most store-bought figs today are self-pollinating, the natural fig–wasp cycle continues in the wild, raising thoughtful questions about how we define vegan foods.
Figs aren’t fruits at all, but rather inside-out flowers. Because of their unique structure, they can’t rely on wind or bees for pollination. Instead, figs take a very different approach, one that has sparked plenty of debate among vegans.
When the time is right, fig trees release a volatile aromatic compound that attracts a highly specific, species-matched wasp. Each fig species has its own dedicated wasp species, and neither can exist without the other.
Because of their enclosed, inverted shape, female figs require wasps for pollination, and wasps rely on figs as a place to incubate their larvae. This tightly interwoven relationship, known as symbiotic mutualism, took more than 65 million years to evolve. In many ways, figs and wasps make each other possible.
A fig wasp can travel over 100 miles in less than two days once it catches the fig’s distinctive scent. When it arrives, the wasp enters the fig through the ostiole, a narrow tunnel-like opening. Squeezing through this tight space comes at a cost: the wasp loses its wings and antennae in the process. But for the wasp, this sacrifice brings it closer to fulfilling its biological purpose.
If the fig is female, the type humans eat, the wasp cannot lay her eggs. She will die inside the fig, but not before delivering pollen that allows the fig to reproduce. The fig, in turn, produces an enzyme called ficin, which completely breaks down the wasp’s body.
If the fig is male, the wasp is able to lay her eggs among the hundreds of internal flowers, creating an ideal nursery. When the larvae hatch, the male wasps, born blind and wingless, spend their entire lives inside the fig. Their sole roles are to fertilize nearby females and carve an exit tunnel. The female wasps then emerge, coated in pollen, ready to seek out another fig and repeat the cycle.
Today, many commercially grown figs are bred to self-pollinate, meaning no wasp ever enters the fruit. In these cases, there is no dissolved wasp involved at all.
Still, the ancient fig–wasp relationship continues to thrive in the wild. Whether or not figs align with your definition of veganism, understanding this remarkable partnership offers a deeper appreciation for the complexity of nature, and the food we eat.
