Unlike periodical cicadas, whose appearances aboveground occur at 13- or 17-year intervals, Neotibicen species can be seen every year, hence their nickname "annual cicadas". Despite their annual appearances, Neotibicen probably take multiple years to develop underground, because all cicada species for which life cycle lengths have been measured ...
This spring’s bugs are part of a genus, or group, of cicadas in the eastern US known as the Magicicada, or periodical cicadas. Three species emerge on a 17-year cycle, and four species are on a ...
The Palaeontinidae or "giant cicadas" (though only distantly related to true cicadas) come from the Jurassic and Lower Cretaceous of Eurasia and South America.

This year is expected to be one for the record books. Brood XIII, which appears every 17 years, and Brood XIX, on a 13-year cycle, will coincide for the first time in over 200 years.
The earliest reports of 17-year cicadas came from the 17th century. While the cicadas may be a nuisance to some nowadays, for people a few hundred years ago, the bugs were truly terrifying.

Once they emerge, they spend their two-week lives climbing trees, shedding their exoskeletons and reproducing. Brood XIII can number up to 1.5 million per acre (3.7 million per hectare).
Dog day cicadas are annual cicadas. They emerge during the heat of summer, usually around July, said Kacie Athey, a specialty crops entomologist with the University of Illinois Extension . The ...
