Blastophaga psenes: male and female wasps inside a fig

a female, and numerous flightless males in a fig.


A fertilised female, loaded with pollen, penetrates an unripe fig via a narrow opening at the top. She oviposits in the female florets within the fig, that develop into a small, globular shining gall; crawling around within the fig she fertilizes many more florets than are galled. From the galls emerge females and apterous males that, after having fertilised a female remain in the fig. The young females leave the fig covered by pollen.
