Cicada maps show where the insects will emerge in the U.S. this spring
Cicadas are poised to return at some point in the spring of 2025, potentially bringing billions of bugs to neighborhoods across the eastern United States.
The group of cicadas set to appear has been labeled Brood XIV. Emerging once every 17 years, Brood XIV is the second-largest group of periodical cicadas — which rise from underground en masse — and will be the only group this spring. That means there will likely be fewer cicadas above ground than there were in 2024, when multiple broods of cicadas emerged at the same time.
Where will cicadas emerge in spring 2025?
Cicadas this year will likely be concentrated in Kentucky and much of Tennessee. The insects from Brood XIV are also expected to show up in parts of Georgia, Illinois, Indiana, North Carolina, Virginia and West Virginia, in addition to smaller pockets farther north in Cape Cod, Massachusetts, central Pennsylvania and Long Island, New York.
CBS News' data team created an interactive map that shows where cicadas are expected to be this year. The map uses information from the University of Connecticut's Cicada Project, which plots the brood's spread based on its known locations in the past.
When will cicadas emerge in spring 2025?
The huge groups of cicadas emerge when the soil reaches a certain temperature in the spring, according to University of Connecticut researchers. In warmer states, cicadas usually come out in late April or May. In cooler states, their arrival tends to occur in May or early June.
How long will cicadas be above ground?
Researchers say cicadas typically remain in a given area for 4 to 6 weeks after they first emerge. Most individual cicadas live for just a few weeks, but, since the emergence itself happens over a two-week period, their eventual fading will also be staggered.
What are cicadas?
Cicadas are a type of insect, related to stink bugs, bed buds and aphids. The ones expected to arrive in droves this year are a variety called periodical cicadas, which appear in huge swarms and often create loud buzzing sounds, according to the National Wildlife Federation. Annual cicadas exist as well.
Periodical cicadas have earned a reputation across eastern North America because of their conspicuous recurrence. Individual "broods" are biologically synchronized to crop up simultaneously in 13- or 17-year intervals, when they rise from their burrows underground in populations that can reach up to the trillions. Between intervals, they live in soil as larvae and feed on fluids from plant roots, the wildlife federation explains.
There are three species of cicadas that emerge every 17 years, and four species that materialize every 13 years, according to researchers at the University of Connecticut. When cicadas share the same emergence year, they're considered part of a brood.
The interactive map below shows where different broods are scattered across the country.

The noise people often hear from cicadas is a mating tactic, according to the wildlife foundation, which notes that male cicadas tend to crowd together and produce raucous choruses in efforts to attract females. Once the mating process has ended, female cicadas deposit their eggs in tree branches. When they hatch, the larvae fall to the ground, burrow into the soil, and the cycle starts again.

A 'new star' has exploded into the night sky — and you can see it from North America
When you buy through links on our articles, Future and its syndication partners may earn a commission. A "new star" is shining in the constellation Lupus thanks to an unexpected stellar explosion within the Milky Way — and it can currently be seen with the naked eye from parts of North America. On June 12, astronomers from the All-Sky Automated Survey for Supernovae at Ohio State University first spotted the new point of light, which had an apparent magnitude of +8.7 at the time, still too dim to be seen by the naked eye, Sky & Telescope originally reported. (A smaller magnitude signifies a brighter object; for example, the moon has an apparent magnitude of -12.7). Over the next few days, the rapidly brightening object took on several temporary names — including AT 2025nlr, ASASSN-25cm, and N Lup 2025 — as researchers scrambled to determine its identity. Astronomer Yusuke Tampo, from the South African Astronomical Observatory at the University of Cape Town, then analyzed the light coming from the object and determined that it is likely a classical nova — a massive stellar explosion that temporarily shines bright in the night sky. On June 16, it was given the official designation V462 Lupi. By June 18, V462 Lupi had brightened to an apparent magnitude of +5.7, which makes it just visible to the naked eye. This also makes it around 4 million times brighter than its extremely dim progenitor star was before June 12, according to Related: Nearly 900 years ago, astronomers spotted a strange, bright light in the sky. We finally know what caused it. There is a chance that the nova will continue to brighten in the coming days, making it even easier to spot. The Lupus constellation is located in the southern sky, meaning that V462 Lupi is most easily visible from the Southern Hemisphere. However, it can also be seen from North America, close to the southern horizon, just after sunset. Amateur astronomers from the U.S. have reported seeing it in places such as Arizona and California, and as far north as Lake Superior, according to Sky & Telescope. You may be able to spot it without any additional equipment. However, it would be easier to spot if you had a decent telescope or a pair of stargazing binoculars, especially if you are viewing it from the U.S. or if the explosion starts to dim over the coming days. Unlike supernovas, which are so powerful that they completely rip stars apart, a nova only affects the outer layer of a star. Classical novas, such as V462 Lupi, occur in a specific type of binary system, where a more massive white dwarf star is pulling material away from its larger partner. When enough material has been accreted onto the dwarf star's surface, the pressure builds up and triggers an explosion that burns up most of the stolen gas and shoots pulses of bright light toward Earth. Naked-eye classical novas are rare. They appear "no more than once a year," representatives wrote, "and most are so close to the limit of naked-eye sensitivity that they can be invisible despite being technically [visible]."

However, astronomers have been predicting that the Blaze Star will reappear imminently for the last 15 months, and it is yet to emerge, which shows that it is not an exact science. As this is the first recorded appearance of V462 Lupi, we have no idea if or when it will explode again in the future.

FDA approves HIV prevention drug taken as twice-yearly injection
The U.S. Food and Drug Administration has approved the drug lenacapavir as a twice-yearly injection to prevent HIV. The drug, called Yeztugo from company Gilead Sciences, was approved Wednesday based on data from clinical trials that showed 99.9% of participants who received it remained HIV negative. Daniel O'Day, Gilead's chairman and chief executive officer, called the approval a "milestone moment in the decades-long fight against HIV." "Yeztugo will help us prevent HIV on a scale never seen before. We now have a way to end the HIV epidemic once and for all," O'Day said in a news release. According to the Centers for Disease Control and Prevention, there were 31,800 estimated new HIV infections in the United States in 2022, the most recent year with available data. While the drug's approval meets an existing need, the Trump administration's funding decisions have rolled back progress for a vaccine. Last month, the administration moved to end funding for a broad swath of HIV vaccine research, saying current approaches are enough to counter the virus. Dr. Barton Ford Haynes, the director of the Duke Human Vaccine Institute, recently told CBS News lenacapavir is a "wonderful development for the field," but said there was still a need for a vaccine. "For HIV vaccine design and development, we've begun to see light at the end of the tunnel after many years of research," Dennis Burton, an immunology professor at Scripps Research, previously told CBS News. "This is a terrible time to cut it off. We're beginning to get close. We're getting good results out of clinical trials." Burton warned that their HIV vaccine research could not simply be turned back on, even if a future administration decided to change course on HIV funding. He said ongoing experiments would be shuttered, and researchers assembled to study the issue would be forced to refocus their careers on other topics. "This is a decision with consequences that will linger. This is a setback of probably a decade for HIV vaccine research," Burton said.

Here's where 17-year cicadas are the worst in Cincinnati, Southwest Ohio. See the map
They're causing chaos at King's Island. They're being blamed for car crashes. Millions of not billions of 17-year cicadas in Brood XIV have emerged in Cincinnati and Southwest Ohio. And even though they've been around for weeks, they are still making themselves known: Screaming from plants and trees, making a mess and peeing on everything. But their time is growing short. Gene Kritsky, professor emeritus of biology with Mount St. Joseph University in Cincinnati, said in a June 16 email that people in the areas heaviest with cicadas should start "to notice things getting quieter next week." What areas are those? Here's where the largest number of cicadas have been in the Greater Cincinnati area, according to Kritsky. Kritsky, founder of Cicada Safari, an app that crowdsources and reviews data on cicadas, was out mapping the 17-year cicada emergence as recently as Monday, June 16, said the heaviest presence of 17-year cicadas have been in Loveland and Mason, northeast of Cincinnati, as well as Pattison Park in Batavia and East Fork State Park in Bethel, both roughly 25 miles east of the Queen City. According to the map generated by Cicada Safari, where users can submit reports of cicada sightings, there have been tens of thousands of reports in Cincinnati and its northern suburbs. But if you head south, crossing the Ohio River into Northern Kentucky, cicada reports dwindle until you hit Louisville and Lexington, per the map. So when will these cicadas go away? The 17-year cicadas are only around for a few weeks, according to the Ohio Department of Natural Resources, as they seek mates and lay eggs for the next generation. And while they started to emerge in mid-May, they are still going strong. Kritsky attributed the slow emergence to cooler, rainy days in May. Cicadas need the soil temperatures to hit 64 degrees to emerge, per ODNR, which typically happens in the second half of May. Following his recent mapping excursion, Kritsky said the big die-off has not yet begun. "The cicadas are still mostly in the trees singing," he said in a June 17 email. But he expects it to start soon. "People should notice the loud singing declining over the next two weeks, and the singing should be over in early July," he said previously. Brood XIV is one of 15 recognized broods of periodical cicadas that emerge every 13 or 17 years, and one of four that appear in the Buckeye State, according to ODNR. They are active for three to four weeks as they focus on mating and reproduction, per ODNR. Male periodical cicadas produce a deafening chorus of calls to attract females. Once mated, female cicadas deposit their eggs into the branches of trees and shrubs. Annual cicadas emerge worldwide each year, but periodical cicadas are found only in eastern North America. They live underground as nymphs for either 13 or 17 years before emerging above ground in massive numbers. Different populations of periodical cicadas are called 'broods' and are numbered with Roman numerals. One of the biggest tourist attractions in Southwest Ohio — Kings Island, in Mason — is also in the center of one of the largest cicada emergences. And some visitors have taken to TikTok to share their disgust, the Enquirer reported on June 11. Videos show people ducking to get away from the bugs, or just running off in some cases. And their screaming is audible in each one. Kritsky told Scripps News Services that he has one important piece of advice for Kings Island visitors. "Just enjoy the cicadas, and when you're on the ride, keep your mouth closed," he said. Brood XIV cicadas of 2025 will stretch from northern Georgia to Massachusetts. In Ohio, they were expected to emerge in a more than dozen counties, per ODNR, mostly in Southwest Ohio: Adams Brown Butler Champaign Clermont Clinton Gallia Greene Hamilton Highland Jackson Lawrence Pike Ross Scioto Warren Washington Some of the edge counties will not see as heavy an emergence as others. The cicadas that emerge every 13 or 17 years are different from the ones seen every summer, and it's not just the amount of time. Kritsky told WKRN in Nashville that periodical cicadas emerge in May or June, while annual cicadas show up later, in late June and July, and through the rest of summer. The two types also look different from each other. Periodical cicadas have black bodies with red eyes and red-orange wings and can be anywhere from three-quarters of an inch to an inch and one-quarter in length. Annual cicadas have dark green to black bodies with green-veined wings and black eyes and are larger. They can grow to an inch and one-third in length. Any animal that can eat insects will eat cicadas, according to the Purdue University Extension. Those include fish, bears, birds, raccoons and even other insects, like parasitic wasps. They're also safe for your dog to eat, to a point. According to the American Kennel Club, a dog that eats the occasional cicada should be fine. However, dogs that gorge on cicadas will find their exoskeletons difficult to digest, resulting in an upset stomach, abdominal pain, vomiting and bloody diarrhea. Some dogs that overconsume cicadas may require a trip to the vet for IV fluids, or pain and anti-nausea medications.
