Subfamily Guides
1- Agaoninae(pollinating fig wasps)
is a of minute chalcidoid wasps comprising the pollinating fig wasps, which maintain an obligate mutualism with Ficus . Females are winged and darkly pigmented, while males are typically wingless and pale. The family has undergone significant taxonomic revision based on molecular , with former Epichrysomallinae, Otitesellinae, Sycoecinae, Sycoryctinae, and Sycophaginae excluded and transferred to other families.

Identification
Minute size (1–3 mm); females with highly modified mandibular appendages for fig entry; extreme with wingless pale males and winged dark females; association with fig fruits (syconia). Distinguished from other chalcidoid by the combination of fig-associated and specialized female mandibular . Formerly broader in scope, now restricted to pollinating lineages following exclusion of non-pollinating .
Images
Appearance
Females are small, winged, and generally dark in coloration. Males are mostly wingless and whitish. Females possess specialized mandibular appendages adapted for crawling through the tight of fig fruits; these appendages are often -specific and may be spiraled to match spiraled ostioles of particular figs.
Habitat
Tropical and subtropical regions where Ficus occur; specifically within the enclosed inflorescences (syconia) of fig trees.
Distribution
Pantropical distribution, following the range of Ficus . Records include: Canary Islands, Sarawak, and broadly across tropical regions of the Palearctic and Oriental realms.
Host Associations
- Ficus - obligate mutualist of fig trees; larvae develop within fig syconia
Life Cycle
Females emerge from ripe figs, fly to developing syconia on other fig trees, enter via the , pollinate flowers, and oviposit into some ovules. These ovules develop into galls housing larvae. Before fig ripening, wingless males emerge, enter galls containing sibling females, mate, and die within the fruit. Females then exit to continue the cycle.
Behavior
Females exhibit directed between fig trees and active pollination of fig flowers. Males do not leave the natal fig; in some fig , males chew exit holes to facilitate female .
Ecological Role
Obligate of Ficus ; the mutualism has persisted for approximately 60 million years with remarkable morphological stability since the Eocene.
Human Relevance
Ecologically significant as maintainers of fig tree , which support diverse tropical forest . No direct economic importance to humans.
