Certain types of fig are male and female and so require a special breed of wasp to pollinate the females.
The female wasp crawls inside through a hole so narrow that she loses her wings in the process and becomes trapped. If the fig is a male, she lays her eggs inside. These hatch into larvae that burrow out, turn into wasps and fly off, carrying fig pollen with them. If the wasp climbs into a female fig, she pollinates it, but cannot lay her eggs and just dies alone.
Luckily for us, the female fig produces an enzyme that digests this wasp completely. The crunchy bits are seeds, not wasp parts.
