They come in hordes of millions, flying in robot-like formations some 3km long and shearing all forms of greenery off a landscape in a matter of hours. Like an apocalyptic science fiction movie—the buzzing crepitations from their wings harmonious with the sci-fi parable. They are locusts—tiddi in Hindi. And India, in the middle of a pandemic, is bracing for a biblical plague, probably the biggest locust outbreak since 1993. The alarms are out, amateur videos of swarms engulfing cropland, villages and cities are aplenty. The latest was from Jaipur, where millenials captured an hour-long flypast on their cellphones. People beat utensils, burst firecrackers. The locusts, for the din they make, hate noise.
