His fervent enthusiasm for flies startled me, until I eventually understood his benevolent motives. A handful of species have colonized the oceansa habitat otherwise unreached by insects. Although none of the individuals would survive on their own, the collective thrives. 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.
