Summary
Seed dispersal is critical for plant reproduction, and plays a key role in shaping ecosystems1. Most seed plants are animal dispersed1, largely by vertebrates — invertebrate-mediated dispersal is rarer and underexplored, apart from seed dispersal by ants (myrmecochory), which disperse seeds of over 11,000 species2. Rare instances of dispersal by other invertebrates, such as wasps, wetas, and beetles, have been reported3,4,5. Despite their global distribution and diversity, flies (Diptera) have never been reported as seed dispersers. Among Diptera, kleptoparasitic flies — notably the genus Bengalia (Calliphoridae) — rob food and offspring from ants6,7,8. Given the overlap in distribution between Bengalia flies and ant-dispersed plants, it is plausible that the flies interact with seed-dispersing ants, but this remains untested. Here, we report the first evidence of seed dispersal by flies.
