New phase proposed in the relationship between figs and wasps | AGÊNCIA FAPESP
Aug 24, But coming across what figs really are ― and the wasp that makes fig, because that's where it lays its larva ― this relationship is known as mutualism. The female fig wasp enters the male fig ― we don't eat the male figs. Aug 29, This relationship with the special wasps and the figs is, as the video above explains, mutually beneficial since both the fig and the wasp need. The current mutual relationship between the two didn't happen overnight. It's the result of millions of years of evolution. The fig plant and the fig wasp both have.
What we call a fig a structure called the syconium is more inverted flower than fruit, with all its reproductive parts located inside. After a female fig wasp flies over from the fig plant she emerged from, she must travel to the center of the syconium to lay her eggs.

To get there, she climbs down through a narrow passage called the ostiole. The passage is so cramped that the tiny fig wasp loses her wings and antenna during her claustrophobic trek.
Once inside, there's no getting back out and flying to another plant -- but is she in the right place? This content is not compatible on this device. Fig plants boast two kinds of figs: If a female wasp enters a caprifig, she'll find male flower parts that are perfectly shaped to hold the eggs she'll eventually lay. The eggs will grow into larvae, which will develop into male and female wasps.
After hatching, the blind, wingless male wasps will spend the remainder of their lives digging tunnels through the fig. The female wasps then emerge through these tunnels and fly off to find a new fig -- carrying precious pollen with them.
You'll Never Be Able To Unlearn What Figs Are
Coevolution is when an evolutionary change in one organism is triggered by a change in a different organism. This will probably sound familiar in the context of the Red Queen Hypothesisbut the relationship does not have to be antagonistic.
Many flowering plants rely on specialized pollinators, who in turn rely on the flowers in some way. Bees and flowers are a classic example of two species that evolved to depend on each other. The bees get a tasty nectar snack, while the flower spreads its pollen to another plant. John Severns; wikimedia commons.
You can see where the ostiole would be on the bottom of the fruit. That's a lot of figs. Everyone knows about those delicious fruits that are a staple of humans, monkeys, birds, and other animals all over the world.
When you eat a fig would you call that a non-Newtonian fig?
Are there really dead wasps in your figs? | MNN - Mother Nature Network
It's a thick bulb filled with tiny flowers that has a small opening at the end an ostiole just big enough for a fig wasp to enter. The wasp emerges from one fig covered in pollen, flies to the next one, and then crawls inside and spreads the pollen to the new fig. Sounds pretty normal right? It turns out that, for many Ficus species, the only animal that can fit through the ostiole is a fig wasp.
A tale of loyalty and betrayal, starring figs and wasps
Normally when a pollinator visits a flower it is looking for food usually a bit of nectar. As the wasp deposits her eggs she also spreads the pollen that she was carrying to the flowers. After laying her eggs, the female dies, and her corpse is broken down by the acids in the fig. When the female wasp arrives, only the female flowers in the fig have developed.
