It remains questionable, however, if the flies observed by Tiensuu were actually feeding on pollen rather than nectar, as I have never noticed pollen grains as gut contents when dissecting male and female flies for identification purposes. It is also stated in the literature (see below), that these flies play no role as pollinators of their host plants.
