2024 is a special year for cicadas ( and cicada lovers , if they ’re out there ) . It marks one of the most significant cicada - related event in centuries : the duple emergence of the 13- and 17 - year broods , Brood XIII and Brood XIX — the big of all periodical cicala broods . While these broods overlap roughly once every five to six years , the specific co - emergence of these fussy dissimilar life cycle is not determine to take place again for another 221 age .

So , how many cicada are expected to emerge this spring ? In short , a pot . While it ’s impossible to know on the nose how many cicadas will make their way out of their hugger-mugger slumbers over the next few weeks , the University of Connecticut’sPeriodical Cicada Projectestimates it will be in thetrillions . This astonishing figure has earned this rare cicada event dub like the “ cicadapocalypse ” and “ 2024 cicada invasion ” across the internet .
However , while the numbers vocalize overpowering , experts have asserted that the average person is unlikely to be significantly affected by this event .
What Are Periodical Cicadas?
There are two form of cicala : periodical cicadas and annual cicala . Both are winged insects known for their distinctive mating sounds — a tatty Greek chorus of buzzing you in all probability associate with the spring and summertime . The differences lie in their life cycles and pattern of emergence from underground .
Annual cicala have a three- to four - year life history cycle and usually appear in July , stick around for the rest of the summer . In direct contrast , periodic cicadas have either a 13- or 17 - year life cycle and tend to come forth in May or former June for a short mating cycles/second ( about four workweek ) before dying off .
Another crucial eminence is the remainder between cicadas and locusts . While cicadas are often mislabeled as locusts , these two species of insects arenotone and the same . Unlike locust tree , cicada are notconsidered pests . They do not swarm and are not destructive to the environment . In fact , cicada are an important part of the ecosystem , returning authoritative nutrients to the stain as they are compost back into the undercoat after their short emergence .
What You Need to Know About the Double-Brood Emergence
There ’s a lot of internet bombilation about this twelvemonth ’s double - brood cicada emergence , but rest assured , it ’s improbable to touch on the average person . That ’s because these two cicada broods do not overlap in geographic range to any important extent . Brood XIII is define to emerge in the Midwest in Illinois , Wisconsin , Ohio , and Iowa , while the expectant Brood XIX is expected to appear in Missouri , Illinois , Louisiana , North Carolina , Virginia , and Maryland .
“ Because the broods do not overlap to any significant extent , the 2024 co - emergence of Brood XIII and XIX will not postulate areas of extremum or ' three-fold ' concentration outside the average of what happens in any other periodical cicada outgrowth twelvemonth , ” the University of Connecticut ’s Periodical Cicada Project observe .
So what about Illinois ? As it twist out , the two brood are require to divide the state in half with minimal overlap . Brood 13 will be in the main in the due north , while Brood XIX will be mainly in the south . accord to the Periodical Cicada Project notes , the peachy chance of overlap will go on in Springfield , IL , but still , it is unlikely that the two broods will co - unify , instead adhere to various quadrants throughout the metropolis .

The Reality of the Cicadapocalypse
All this to say , while the emergence of these two cicada radical is pregnant in entomology and periodical cicadas , the average someone wo n’t see much of an impact . Living in the Midwest and Southeast United States , you’re able to expect to hear the periodical brood cicala from recent May through the oddment of June .
The most significant affair to remember is that cicadas are not pest , and you should not seek to kill them . They are part of an of import symbiotic relationship in our ecosystem and will not cause any harm or hurt to the surrounding environs . So sit back , slacken , and savour the sound of summertime as the cicadas depart to sing .
