Agaonidae

Definition

A family of minute chalcidoid wasps (Hymenoptera: Chalcidoidea) comprising the pollinating fig wasps, whose larvae develop inside the enclosed inflorescences (syconia) of Ficus species. Females enter through the ostiole to oviposit and pollinate, establishing an obligate mutualism with their host figs; males are typically wingless, short-lived, and mate within the syconium before females disperse.

Etymology

From New Latin Agaonidae, derived from the type genus Agaon (from Greek agáōn, present participle of agáō, 'to admire' or 'to worship') + -idae, the family suffix.

Example

Blastophaga psenes (Agaonidae) is the specific pollinator of the common fig, Ficus carica; female wasps carry pollen from their natal syconium and actively pack it into the stigmas of a new fig, ensuring both seed set and oviposition sites for their offspring.

Synonyms

• fig wasps (informal, also includes non-pollinating fig wasps in other families)

Usage Notes

The family historically included non-pollinating fig wasp subfamilies (Sycophaginae, others) now placed in Pteromalidae; current Agaonidae is restricted to pollinators. The term 'fig wasp' broadly applies to multiple families associated with figs, so specialists prefer 'agaonid' or 'pollinating fig wasp' for precision. Male agaonids exhibit extreme morphological reduction—lacking wings, eyes, and functional mouthparts—and never leave the syconium.
