In terms of diversity and sheer numbers, Mr. Balcombe writes, the flys success takes on celestial proportion. Some researchers estimate that there are 17 quadrillion flies on the planet. Although none of the individuals would survive on their own, the collective thrives. One British fly expert believes that for each human there are about 17 million flies. Born to Dutch parents, tenOever grew up in rural Ontario. There are 160,000 known species of flies, and thats probably only scratching the surface. Flies, which have been around as long as humans, exist on every continent, including Antarctica.
