Once Art Borkent starts speaking about biting midges, he rarely pauses for breath. Holding up a picture of a gnat trapped in amber from the time of the dinosaurs, the 72-year-old taxonomist explains that there are more than 6,000 ceratopogonidae species known to science. He has described and named more than 300 midges, mostly from his favourite family of flies. Some specialise in sucking blood from mammals, reptiles, other insects and even fish, often using the CO2 from their host’s breath to locate their target, he says. Tens of thousands remain a mystery to science, waiting to be discovered.
