According to the map, Oklahoma's most prevalent brood of periodical cicadas is Brood IV, which last emerged in 2015 and is next expected in 2032. Brood XIX will make an appearance in southeastern ...

All other cicadas from other biogeographic regions produce annual broods, so the distinction is not made outside of North America. Species called "annual cicada" include members of the genus Neotibicen ("dog-day cicadas"), Diceroprocta , [ 2 ] Neocicada , [ 3 ] and Okanagana . [ 4 ] (

Trillions of cicadas will appear throughout the US as two broods emerge simultaneously. The natural phenomenon only occurs every 221 years.
Given that most broods produce localized population numbers exceeding 1.5 million cicadas per acre (0.4 hectare) in densely populated areas of their distribution, there easily will be more than a ...
Brood XIII of the 17-year cicada, which reputably has the largest emergence of cicadas by size known anywhere, and Brood XIX of the 13-year cicada, arguably the largest (by geographic extent) of all periodical cicada broods, were expected to emerge together in 2024 for the first time since 1803.
In 2013, the USDA Forest Service published this detailed map of the 15 periodic cicada broods in the U.S. and their emergence years between 2013 and 2029.
