Corybas Pollinators

Rudie Kuiter’s Short Paper 5, October 2017, is about he and his team’s observations on the pollination strategies of fungus-gnats with Corybas. A small section from the introduction is quoted below:

Certain flowers in large colonies were most popular over several days and both sexes were observed feeding on the boss, which suggests a food-related attraction. Virtually nothing was known about the Corybas pollinators and primary literature to date only offered hypotheses. Based on our findings, the persisting statement in literature that ‘Corybas species attract fungus-gnats as putative brood-sites’ is incorrect for the taxa in Victoria. No evidence of ovipositing in flowers was found. Females feeding looked gravid and were presumed to be unfertilised. All individuals looked fresh with undamaged wings and it was apparent they had recently hatched.

Is this a hypotheses that needs revising? Rudie definitely demonstrates the importance of careful and meticulous observations.
