The family as presently defined is polyphyletic, including several unrelated lineages whose similarities are based upon their shared association with figs; efforts are underway to resolve the matter, and remove a number of constituent groups to other families, particularly the Pteromalidae and Torymidae. Thus, the number of genera in the family is in flux. Probably only the Agaoninae should be regarded as belonging to the Agaonidae, whilst the Sycoecinae, Otitesellinae and Sycoryctinae should be included in the Pteromalidae. Placement of the Sycophaginae and Epichrysomallinae remains uncertain. In biology, a taxon is polyphyletic if it is descended from more than one root form (in Greek poly = many and phyletic = racial). ... Torymidae is a family of wasps that consists of rather slender species. ...


Among the Agaonidae, the female is a normal insect, while the males are mostly wingless. The male's only tasks are to mate with the females while still within the fig syconium and chew a hole for the females to escape from the fig interior. This is the reverse of Strepsiptera and the bagworm, where the male is a normal insect and the female never leaves the host. strawberry: the seeds are the real fruits achenes An accessory fruit is a fruit where the fleshy part is derived not from the ovary but from some adjacent tissue. ...

Most figs have three kinds of flowers: male, short female, and long female. Female fig wasps can reach the ovaries of short female flowers with their ovipositors, but not long female flowers. Thus the short flowers grow wasps, whereas the long flowers become seeds. In figs of this sort, the crunchy bits in the fruit contain both seeds and wasps. However, there are several commercial and ornamental varieties of fig that are self-fertile and do not require pollination; these varieties are not visited by fig wasps. Clivia miniata right hereflowers. ...


Pollinating fig wasps (Agaoninae) are specific to specific figs. The common fig Ficus carica is pollinated by Blastophaga psenes.

Who_pollinates_fig_trees (376 words)
Fig trees are unique in that the flowers are completely concealed within the fig, an enclosed inflorescence, with the hundreds of tiny florets lining the inside of a central cavity.
These fig wasps are the sole pollinators of fig trees and in turn, fig wasps can breed nowhere else but inside figs, a relationship that is a classic example of an obligate mutualism (neither party can survive without the other) that has evolved over the last 90 or so million years.
Each fig tree species is usually pollinated by one fig wasp species that is only associated with that fig species, a host-specific relationship that plays a major role in the prevention of hybridisation between different species of fig trees.
