Figs and Fig Wasps | HowStuffWorks
to know more about the close relationship between different The wasp pollinates the tree. In return the tree offers its figs to the wasp as a safe place for it to. In an article published at journal Acta Oecologica, Brazilian biologist Luciano Palmieri Rocha has proposed a new phase of the development.

The flowers that receive pollen but no eggs develop into seeds. Flowers that receive eggs undergo a transformation to become hardened structures called galls, becoming nurseries with food and shelter for wasp larvae. The D phase occurs at the end of larval incubation. This is also when the male flowers start to mature, opening up to expose pollen containers known as anthers.
The first wasps to emerge from the galls are wingless males with reduced eyes but large strong mandibles," Palmieri said. The male penetrates the female with a telescopic penis and fertilizes the female inside the gall. Once they have mated in this way, the males use their mandibles to bite through the fig wall. They then go out through the hole, fall to the ground and die.

Leaving the receptacle through the hole made by their brothers, the fertilized females fly away in search of other fig trees, and the cycle begins again. The E phase consists of seed dispersal through the feces scattered by the vertebrates that feeds from figs. The proposed F phase Evidence of the new F phase began to appear over the course of years of observation.
These figs were discarded and left out of the research.
Are figs really full of baby wasps?
In some cases, larvae that were almost the same size as the fig had eaten almost its entire contents. That's when we decided to investigate what was going on," Palmieri said. In the article just published, I describe insects belonging to five orders and 24 different families that are not fig wasps but that also interact with figs, performing different functions.
These insects may colonize figs during different phases of the tree's lifecycle. Some rely on fallen figs to complete their development. Palmieri divided the insects into two categories according to their role in the fig tree's ecology and their potential impact on its reproduction. He called the categories "early fig interlopers" and "fallen fig fauna.
The fly larvae migrate to the interior of the fig and feed exclusively on yeast and bacteria brought inside by the pollinating wasp. The flies finish their development inside the fig and leave by the exit hole previously chewed in the fig wall by male wasps. The female wasps then emerge through these tunnels and fly off to find a new fig -- carrying precious pollen with them. If a female fig wasp enters an edible fig, she eventually dies from exhaustion or starvation.
The female flower parts include a long stylus that hinders her attempts to lay her eggs. She may die, but she succeeds in delivering the much-needed pollen first.
New phase proposed in the relationship between figs and wasps
So a fig farmer winds up with caprifigs full of wasp eggs and edible figs full of seeds. Though edible figs may not be filled with baby wasps, doesn't this mean that these figs contain a lot of female wasps who died of loneliness? Read on to find out what or whom you're munching on when you grab a fig treat.
We're used to seeing figs as fully ripened fruit, but before they're pollinated, there's actually plenty of room in there for a female wasp to lay her eggs in the tiny flowers.
She reaches those flowers by flying through a narrow passageway, usually losing her wings and antennae in the process. The eggs grow into larvae, then young wasps. The male wasps spend their lives digging tunnels through the figs from which the females can emerge until—you guessed it—they die.
If a female wasp chooses the wrong fig tree, however, she'll die too. Female wasps can only lay eggs in the figs from male trees, not female ones. But here's where it gets tricky: If they accidentally lay their eggs in the female figs, they'll die there.
