A brood XIX cicada crawls up a tree in North Carolina, US on May 1, 2024. These cicadas have a 13-year life cycle, so this one has come from an egg laid by its mother in in 2011. Brood XIX’s emergence this spring coincides with the arrival of another brood that is on a 17-year cycle; entomologists say this may result in an influx of more than 1tn cicadas across 16 states.
