| Outline of Final Research Achievements |
This study has shown that many of the species of the Phyllanthus genus (Phyllanthaceae) are pollinated by Cecidyomiidae gall midges that use male flowers as brood sites. Many gall midge pollinated Phyllanthus species possess dark red floral display and are found across multiple lineages within the genus. Gall midge pollination, together with pollination by Epicephala moths that use fruits as brood sites, is widespread in the genus. Evolutionary alternation between the two pollination systems has likely contributed to the generation of high species richness of Phyllanthus. The study also found that many plants with similar dark red flowers are pollinated by fungus gnats, revealing a previously overlooked pollination syndrome.
