Locust Swarms, Some 3 Times the Size of New York City, Are Eating Their Way Across Two Continents | InsideClimate News

Huseman said that, in the global warming era, other parts of the world may also need to prepare for unexpected insect invasions as part of larger scale shifts in the distribution of animals. In northern Germany, for example, scientists recently spotted Asian wasps for the first time. A 2013 study found that crop-damaging insects are moving poleward at about 4 miles per year.

In addition to the ongoing plague of locusts around the Horn of Africa, there have been recent outbreaks of varying intensity in places like Sardinia, in the Mediterranean Sea, and Las Vegas.

David Inouye, a University of Maryland biologist who studies the effects of global warming on plants and animals, said conditions favoring outbreaks are becoming more common.
