𓆦 𓆦 Cicadas Are Here ¯\_ ( ･_･) _/¯ 𓆦 𓆦

*Periodical cicadas (Magicicada species) are unusual insects, found only in eastern North America. While there are about 150 species of cicadas in the U.S., only seven Magicicada species have synchronized their development to create periodical emergences. The rest are annual cicadas that appear every year in summer.*(2)
**Generally, a 13-year brood emerges in the same year as a 17-year brood roughly every 5-6 years, though most of the 17-year broods are not in contact with a 13-year brood, so the different cicadas are clearly separated in space. A co-emergence involving adjacent broods of different life cycles is something that happens only roughly every 25 years. Any two specific broods of different life cycles co-emerge only every 221 years.
2024 is a special year for periodical cicadas:
For the first time since 2015 a 13-year brood will emerge in the same year as a 17-year brood.
For the first time since 1998 adjacent 13-and 17-year broods will emerge in the same year.
For the first time since 1803 Brood XIX and XIII will co-emerge.
You will be able to see all seven named periodical cicada species as adults in the same year, which will not happen again until 2037. You will not see all seven named species emerge in the state of Illinois again until 2041.**(1)
