Step 1 : Introduction to the question "Which insect is necessary to pollinate figs?"
...Specific types of figs require a certain breed of wasp to pollinate them. A female wasp pushes her way inside the fig through a tiny hole, one so narrow that it tears her wings off as she squeezes through. She becomes trapped inside. She lays her eggs inside if the fig is male. These hatch, burrow out and fly off, carrying the fig's pollen with them. If the fig is female, the invading wasp pollinates it. She can't lay her eggs and dies inside the fig, all alone. The fruit produces a digestive enzyme that completely digests the wasp. Source: ScienceFocus.com
