Rhinomyiophily is largely a Cape Flora phenomenon. Well documented by Vogel in 1954, a consists of a guild of flies with long beaks (some carried forward like spears, others straight down like brooms and others with them tucked below and between their legs) in several families - mainly Bombylidae, Tabanidae and Nemestrinidae.

Plants pollinated by these flies have long, very thin tubes, with flags at the front (distal) end to attract the flies and - just as importantly - guide the tongues into the flowers. The flies have to hover in front of the flowers in order to insert their beaks. They tend to be big, to fly in spring, on hot, less windy, days around midday.

This is a fascinating Syndrome: here we collect both the flies and the flowers.
