FLASHBACK PHOTO: UNITED PRESS PHOTO, NATIONAL GEOGRAPHIC STOCK The Coming Plague A cloud of plague locusts descends on a field outside Melbourne, Australia, in 1955. Such swarms usually occur in years of plentiful rain, when conditions are most favorable for successive generations to reproduce quickly. But locusts can and do travel great distances, so even drought-stricken regions can be stormed by the hungry bugs. Last year was a particularly good year for Australian plague locusts---and a bad year for those who had to live with them. In Victoria state, motorists were urged to be wary of swarms. "As their fat-laden bodies can measure up to 42mm [1.6 inches]," warned Michael Case of the Royal Automobile Club of Victoria, "when they impact on a windscreen they literally explode. This leaves a sticky residue that may render windscreen wipers useless and can very quickly obscure a driver's vision." ---Margaret G. Zackowitz O Flashback Archive Find all the photos at ngm.com.
