Ohio cicada map 2025: When will cicadas go away? How deep do they burrow?
Is the cicada season over yet in Ohio? If you're reading this in Greater Cincinnati, you've probably seen the cicadas swarming around the city. After these adult cicadas mate, they will lay eggs, and their cicada babies (known as nymphs) will hatch after a few weeks. How far into the ground will the nymphs burrow when they hatch from their eggs? Here's a little biology lesson. After six to ten weeks, cicada nymphs will hatch. They appear white and ant-like when they hatch, according to the Ohio State University Extension. Once they hatch, they drop to the trees and immediately burrow around 6–18 inches below the ground. The nymphs then spend the next 13 or 17 years below ground before emerging to continue the life cycle. Millions, if not billions, of cicadas (whether you like them or not) have emerged in Cincinnati, Southwest Ohio, Northern Kentucky, and Southeast Indiana. This brood of cicadas is XIV (14), the latest brood of 17-year cicadas to emerge in the United States. The duration of the cicadas' presence depends on the brood and whether they are annual or periodical species. Once periodical cicadas have mated and the females have laid their eggs, the insects will die after about three to six weeks above ground. That means many of this year's periodical cicadas could go away in mid-June, according to The Nature Conservancy. However, Gene Kritsky, professor emeritus of biology with Mount St. Joseph University in Cincinnati, said that Cincinnati's cicadas are still approaching their peak in many areas. Kritsky, founder of Cicada Safari, an app that crowdsources and reviews data on cicadas, attributed their continued presence this late into June to the cooler, rainy days in May. The eggs will hatch in early August and nymphs will burrow into the soil, while the dead adult cicadas will fall back to the ground, helping to fertilize the soil while leaving a stinky, terrible mess. This 2025 brood has emerged in great numbers along the I-71 corridor near Cincinnati, per The Enquirer. All or part of several other counties in Southern and Southwest Ohio are experiencing cicadas this year. Here are the counties that are getting hit the hardest: Adams Brown Parts of Butler Clermont Most of Clinton Most of Gallia Parts of Hamilton Highland Parts of Ross Most of Warren In two years, a 13-year brood is expected to emerge in Brown and Clermont counties southeast of Cincinnati, as well as 10 other counties in Northern Kentucky. Ohio will then see cicadas again in 2033, 2036 and 2038, according to Cicada Mania.

Millions of cicadas have emerged in Ohio. How many eggs can a female cicada lay? What to know
Cicadas have started to emerge around Cincinnati this year. This brood of cicadas is XIV (14), the latest brood of 17-year cicadas to emerge. Cincinnati, Southwest Ohio, Northern Kentucky and Southeast Indiana will see millions, or even billions, of bugs from this brood. There are always so many cicadas, but how many eggs do female cicadas lay? Let's take a look at what we know. There are millions, if not billions, of cicadas flying around Cincinnati, Northern Kentucky and several other states right now. How are there so many cicadas when they emerge? Because the females are egg-laying machines. Female cicadas can lay up to 600 eggs, inserting them into the branches of trees and shrubs with their ovipositor (egg-laying organ), according to the University of Massachusetts. When cicadas emerge, you'll likely find them on trees. Adult cicada males make their well-known deafening 'buzzing,' or singing sound, to attract females to mate. Up to 10 weeks later, after the eggs hatch, the nymphs drop to the ground and dig into the soil, feeding on host plant roots. Their underground stages will mostly go unnoticed until the next time adult cicadas emerge. Whether or not you enjoy this biological phenomenon, only one brood of cicadas has popped out this year. Not two, like last year. In 2024, two periodical broods appeared. Brood XIX, which has a 13-year life cycle, and Brood XIII, which has a 17-year life cycle overlapped in parts of the Midwest last year, according to Cicada Mania. The lifespan of cicadas depends on the brood and whether they are annual or periodical species. Brood XIV is one of 15 recognized broods of periodical cicadas that emerge every 13 or 17 years after living as nymphs underground. It is also one of four broods that appear in the Buckeye State. Once male and female periodical cicadas have mated and the latter has laid eggs, the insects die after spending only a few weeks above ground. That can be anywhere from three to six weeks after first emerging. The Brood XIV cicadas won't be crawling and flying around only in Ohio this summer. If you plan to take a summer vacation in another state, you may find them in: Georgia Indiana Kentucky Massachusetts North Carolina New Jersey New York Pennsylvania Tennessee Virginia West Virginia This article originally appeared on Cincinnati Enquirer: Cincinnati swarmed by cicadas.

'Greater Eastern Brood' cicadas are making their return to Tennessee. Why they're considered 'near threatened'
It's around that time of year, when the air - and ground - is filled with the sights and sounds of millions of buzzing cicadas. In 2025, Tennessee will see the emergence of Brood XIV, a 17-year periodical cicada. The last time this brood emerged was in 2008. According to Cicada Mania, the loud guests will most likely be spotted north of Nashville, north-west of Chattanooga and in random places across East Tennessee. Counties most likely to spot cicadas include: Bledsoe, Blount, Campbell, Carter, Cheatham, Claiborne, Cocke, Coffee, Cumberland, Davidson, Grainger, Grundy, Hancock, Hawkins, Jefferson, Marion, Putnam, Roane, Robertson, Rutherford, Sevier, Sumner, Unicoi, and Williamson. Here's what to know about this year's cicadas as they begin to emerge from their underground burrows. The three 17 year species of cicadas — Magicicada septendecim, Magicicada cassini and Magicicada septendecula —are all considered 'near threatened' by the International Union for Conservation of Nature, meaning the species does not currently meet the criteria for critically endangered, endangered, or vulnerable status, but it is close to qualifying for or is likely to qualify for a threatened category. All three species were listed as near threatened in 1996, 12 years before their last emergence. Brood XIV is one of the largest 17-year periodical cicada broods. According to the University of Connecticut, it is the second largest after Brood XIX and is larger than Brood X, earning it the nickname "Greater Eastern Brood." Brood XIV emerges eight years after Brood VI, four years after Brood X, and four years before Brood I. According to Cicada Mania, millions of Brood XIV cicadas will emerge in the spring of 2025, and will most likely begin appearing in May across 13 states, including Tennessee. These cicadas typically emerge when the soil, 8 inches below the surface, reaches around 64 degrees. Above-ground temperatures in the 70s to 80s help warm the soil to this point. Often, a warm rain can trigger their emergence, wrote Cicada Mania. Cicadas will stick around throughout the spring and into the summer months. They are likely to leave by late June 2025. In 2025, cicadas will primarily emerge in states located in the eastern half of the country. States welcoming the noisy visitors include: Georgia Indiana Kentucky Massachusetts Maryland North Carolina New Jersey New York Ohio Pennsylvania Tennessee Virginia West Virginia Tennessee won't see the next periodical emergence of cicadas until 2028, when the 13-year cycle Brood XXIII cicadas return. According to Cicada Mania, they will most likely be seen throughout West Tennessee. Diana Leyva covers trending news and service journalism for The Tennessean.

They're back! Cicadas are back for 2025 in Tennessee. Here's where Brood XIV is emerging
They're baaack! Did you miss them? Cicadas have started to reemerge for the 2025 season. The bugs are generally harmless, but the drone of their buzzing will quickly become a nuisance for Tennesseans. The 17-year periodical Brood XIV cicada will be the predominant cicada species haunting Tennessee in 2025. This species of cicada was last seen in 2008. The bugs arrived as forecast; in late April or early May, when the soil temperature at eight inches deep reached 64 degrees. Until June, these large, red-eyed insects will be in just about every corner of the Volunteer State. Here's what to know about the noisy bugs and their tenure in Tennessee this summer. Have there already been cicada sightings in Tennessee? A cicada rests on the jersey of Providence Academy's Luke Mcintosh (28) before the start of the Division II Class A TSSAA baseball tournament game against Columbia Academy on Tuesday, May 21, 2024 in Murfreesboro, Tenn. Cicadas are coming out all across the eastern half of the United States, especially in Tennessee and Western North Carolina. A preliminary report from Cicada Safari shows a whopping 360 Cicada sightings near Asheville. There have been 35 sightings near Pigeon Forge, 26 in southeast Tennessee and another seven near Knoxville. Nashville has 18 reported sightings, according to the Cicada Safari map. Which states will have cicadas in 2025? Thirteen U.S. states, including Tennessee, will see cicadas this year. States getting cicadas in 2025 are concentrated in the eastern half of the country: Georgia Indiana Kentucky Massachusetts Maryland North Carolina New Jersey New York Ohio Pennsylvania Tennessee Virginia West Virginia When are the cicadas coming to Tennessee? Cicadas will begin to emerge from their underground burrows in the springtime, once the temperature reaches about 65 degrees, according to Cicada Mania. You'll likely start to see cicadas in the Volunteer State during the fourth week in April or the first week in May, according to Gene Kritsky, founder of Cicada Safari. Southern Tennessee will be first to hear the buzz of cicadas, then the insects will start coming out in the northern part of the Volunteer State. How long will the cicadas be in Tennessee? The Brood XIV cicadas will only stick around in Tennessee for a few weeks. The periodical cicadas will be present as early as April 2025 and should disappear again by late June, according to Cicada Mania. When will the cicadas go away in Tennessee? This is probably your most pressing cicada-related question: When will they finally be gone?!? Cicadas will likely have gone away in Tennessee by late June 2025. Cicada emergence map 2025 How long do cicadas live? The lifespan of a cicada varies. There are over 3,000 species of cicadas, according to National Geographic. The Brood XIV cicadas generally have a lifespan of about 17 years. Are cicadas blind? No. Cicadas actually have excellent vision, according to the University of Connecticut biodiversity research collections. CIcadas' supposed blindness is a myth because periodical cicadas don't care about where they land. Can cicadas bite? No. Cicadas do not bite, nor do they sting. Though they are annoying, the bugs are not considered to be harmful. Can dogs eat cicadas? While cicadas are not inherently toxic for dogs, the American Kennel Club recommends stopping your pups from eating the bugs. If dogs eat one or two cicadas, the dogs likely will be OK. However, if dogs eat too many, the bug's exoskeleton will become difficult to digest. This can cause your dog to have severe stomach upset and abdominal pain, vomiting and bloody diarrhea, according to the American Kennel Club.

Cicadas could emerge soon in Massachusetts. Here's what to expect.
The emergence of cicadas could start any moment now. Last year, the country witnessed a surge of the insects but they were not in Massachusetts. This time around, the 17-year periodical cicadas, also known as Brood XIV, will emerge. "Cicadas emerge when the soil temperature reaches about 64°F at a depth of 12–18 inches," according to The Nature Conservancy. So, when will the cicadas start appearing? And how long does the cicada emergence last? Here's what to know. The Nature Conservancy stated on its website that cicadas arrive as early as May and stay until late June. WBUR radio in Massachusetts stated on its website that cicadas will most likely appear in mid-May, but more likely near the end of the month or early June. The Nature Conservancy stated on its website that cicadas will remain in the region for a period of four-to-six weeks, adding that "the exact time of emergence can vary depending on the specific brood and soil temperatures." There are more than 2,000 species of this insect worldwide, according to Mass Audubon the most common in Massachusetts being the "Dog Day" cicada, which arise every two years or so. The Dog Day cicada is "approximately 2.25 inches long, medium brown, with a green venation, the vein structure in its wing." The "periodical" cicada comes out once every 17 years, and are a bit smaller than Dog Day cicadas, with black bodies, Mass Wildlife explained. The periodical creatures are the ones people are clamoring for this year. What they're most known for is their ability to make a racket, able to generate noise reaching 100 decibels. Cicadas can typically be heard "singing" during late summer days, according to Mass Wildlife. The cicadas make such sounds with organs in their bodies called tympana. According to Mass Audubon, "cicadas are among the most benign of insects" and do not typically carry any sorts of disease. The organization added that they do not hurt pets, either. Brood XIV is the one that will emerge in parts of the United States this year, according to The Nature Conservancy. The last time this particular brood of cicadas was around was 2008. Historical dates for Brood XIV in Massachusetts include appearances over the 1700s, 1800s and 1900s in Barnstable, Dennis, Falmouth, Bourne, Plymouth and a handful of other nearby towns. The cicadas will only be seen in 12 other states when they arrive, including Georgia, Kentucky, Indiana, Maryland, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia and West Virginia, according to Cicada Mania. In 2024, two broods of "periodical" cicadas – 13-year brood Brood XIX and the 17-year Brood XIII – emerged from the ground at the same time last summer. That's a rare occasion in itself - it's not often that two such broods arise at the same time. It hadn't happened in 200 years. However, the convergence of the two broods mostly occurred in the southern United States, so Massachusetts residents weren't able to see the full spectacle.
