How long do cicadas last?

Cicada individuals last above ground anywhere from a few seconds to about a month at max (maybe longer in captivity). This depends on the species. A periodical cicada emergence typically lasts about 5 to 6 weeks — the key is they don’t all emerge at once. Some annual cicadas can be found 4 months a year in the same location, like Neotibicen tibicen.

Magicicada cicadas come out once every 17 or 13 years. Brood X is every 17 years. There are 12 Broods of 17 year cicadas, and 3 Broods of 13 year cicadas. Mathematically speaking, each year there is an approximately 78% chance a Brood is emerging somewhere in the US. If we’re taking about other types of cicadas, they’ll be around late-spring and throughout the summer. Other species range from just 2 years, to as many as 19!

How how to pronounce cicada?

You can pronounce cicada however you like, but the most popular ways are ci-KAY-duh or si-KAH-duh. I prefer si-KAH-duh because that’s how they say it in Australia and that’s how William T. Davis pronounced it, and he had the largest collection of cicadas in North America.
