Brood’s Clues: New Mapping Approach Puts Cicadas in Focus

More than 20 broods of periodical cicadas inhabit the eastern United States, and researchers are refining their mapping of brood ranges with increasing precision at every new emergence. A new report in the Annals of the Entomological Society of America details new advances in mapping cicadas from researchers who studied Brood VI in 2000 and 2017.

Got Cicadas? Take a Picture and Help Entomologists Map Their Arrival

Scientists are looking to the public for help in mapping 17-year cicadas in the massive Brood X due to emerge from the ground this spring in the eastern U.S. The citizen-science effort, powered by a smartphone app, could generate the biggest-ever observation data set in the history of cicada research. Here's how you can participate.

When Cicada-Killer Wasps Become Cicada-Stealer Wasps

Hunting cicadas and lugging them back to a nest is hard work for a cicada-killer wasp. But sometimes all that hard work goes to waste, when a fellow wasp swoops in and lays her egg on the other wasp's prey. And that's if the cicada isn't stolen by a bird first.
