Cicadas Are Coming: Here’s What We Know About Brood XIX and Brood XIII

Get ready for double the cicada buzz in 2024, depending on where you live.

Ah, the sounds of summer. Splashing waves at the beach, a lawn sprinkler spinning deliriously, the bells of an ice-cream truck … and the constant buzz of cicadas. If you live in certain states, get ready, because they’re coming back in 2024.

Cicadas, winged insects with an especially loud song, have a weird life cycle. They grow underground, but we humans mostly pay attention to them when they emerge into our above-ground world.

There are annual cicadas, which emerge from their underground life every year at various times. Then there are periodical cicadas, which emerge only every 13 or 17 years. Those groupings are called broods and are numbered. Because of their trackable schedule, these broods of periodical cicadas tend to steal all the headlines from their annual cicada comrades.

This summer, it’s a double-brood year. That’s rare. According to ScienceAlert, the last time it happened was in 1803. One brood on a 13-year-cycle — called Brood XIX — and another on a 17-year cycle — called Brood XIII — are expected to pop out of the ground in 2024.

Here’s what to know before they take over your neighborhood between May and June, including how to protect your hearing from all that cicada noise — and whether climate change could be responsible for be disrupting the cicada cycle.

What’s expected in 2024

Brood XIX

Brood XIX, also called the Great Southern Brood, is the biggest brood of 13-year periodical cicadas, if you go by geographical distribution. It was last seen in 2011 in the Southeast US. Most periodical cicadas are on a 17-year cycle, but Brood XIX is on a 13-year cycle. The two other surviving 13-year broods are expected to return in 2027 and 2028.

This brood is expected to re-emerge in mid-May and stay around through late June. The cicadas tunnel to the surface, mate, lay their eggs and then die off. Look (and listen) for them in Alabama, Arkansas, Georgia, Illinois, Indiana, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee and Virginia.

Brood XIII

Brood XIII is known as the Northern Illinois Brood. (Illinois seems to appeal to cicadas more than any other state. Experts at the University of Connecticut say that the Land of Lincoln “contains both 13- and 17-year life cycles, all seven currently recognized species, and five separate broods, some of which include disjunct populations.” Talk about the Big Noise from Illinois.

This is one of the 17-year cicada broods. It was last seen in 2007 and should be back from mid-May to late June, just like Brood XIX. They are expected to appear in Illinois, Indiana, Iowa, Wisconsin and possibly Michigan.

The basics about cicadas

According to the EPA, cicadas are about 1 to 1.5 inches long, with a wingspan twice that length. They have black bodies, red-brown eyes and membranous wings with orange veins. The noise that makes them famous is the loud courting sound of the adult males.

The name of the species is pronounced differently in the US, where most people say “suh-KEI-duh,” than it is in the UK, where people tend to say, “suh-KAA-dah.”

What to do about the cicadas

Live and let live — they’re temporary and harmless. Cicadas may be noisy, but they don’t bite or sting. And unlike termites, they won’t chew their way into your house, though they could enter through open doors and windows as other insects can. In fact, pest-control experts say that pesticides don’t work on cicadas.

“It’s a waste of (pesticide), and it’s a danger to the environment just to spray down because you’re afraid of the cicadas,” one expert told CNET in 2021.

How can you manage the cicada noise?

The main problem with the cicadas is obvious: their constant buzzing noise. They’re around only for about six weeks, however, so experts have some ideas for how to keep the sound from driving you buggy.

These aren’t cicada-specific remedies, but they work. You might try noise-canceling headphones, white-noise machines or simple earplugs. You can also try some DIY soundproofing, such as weather-stripping foam tape.

Climate change and cicadas

Climate change brings rising global temperatures, and the cicadas aren’t working with a calendar, they’re reacting to temperatures. So it’s unsurprising that scientists believe climate change affects the cicadas as well.

Chris Simon, a professor in the department of ecology and evolutionary biology at the University of Connecticut, has studied and researched cicadas for years.

“Warmer winters and earlier springs will cause cicadas to come out earlier,” Simon told CNET. “Warming climates also increase the growing season in a given area so that cicadas may be ready to emerge from the ground years earlier — generally four years earlier — turning 17-year cicada populations into temporary 13-year cicadas. If this happens repeatedly, we hypothesize that 17-year cicadas could become permanent 13-year cicadas.”

But that change wouldn’t reduce the number of cicadas, Simon told CNET, just adjust their schedule. And it shouldn’t affect the food chain, because “the animals that eat them above ground would see them more often, and the animals that eat them underground would still do so,” Simon said.

While it’s possible that climate change could force the cicadas to move farther north, that won’t be an immediate change. Simon notes that periodical cicadas can move only as adults, and that can happen only for about for weeks every 13 or 17 years. While periodical cicadas can fly, they tend not to move much or migrate long distances. Human-made asphalt and cement obstacles could also prevent the cicadas from taking off to the great white north.

How you can help cicada researchers

Want to help scientists learn more about periodical cicadas?

“Citizen scientists are critical for filling in the parts of the distribution that we do not have time to visit or unknown parts of the distribution that we can later verify,” Simon told CNET.

To help you can download Cicada Safari for iOS or Android, a free app developed by Simon’s colleague Gene Kritsky. The app asks people to take a cicada photo using their phone, with geolocation allowed.

“(Kritsky’s) team will verify photos and log the data and share it with us,” Simon said.

How to protect new, small trees from cicadas

While cicadas shouldn’t hurt large, mature trees, new young trees may be vulnerable. Female cicadas like to lay their eggs on trees where new leaves are located, puncturing the branches and possibly causing leaves to wither, turn brown and even snap. So if you live in a cicada territory, hold off on planting any new trees until they’re gone, which should be in late June.

If you have new small trees and are worried about cicada damage, you may want to loosely wrap their trunks and the areas where twigs meet the branches. You can use cheesecloth, foil tape, barrier tape or sticky tape. You could also use landscaping nets around smaller trees. CNET has a guide to tree protection against cicadas.

People eat cicadas?

This last bit isn’t for everybody, but you can actually eat cicadas. Don’t even try it, though, if you have seafood allergies, because cicadas are related to shrimp and lobster.

If you’re made of tough stuff and don’t get easily queased-out by unusual foods, there are plenty of simple cicada recipes on the web. An expert from Johns Hopkins University says they’re “quite tasty” but admits “the yuck factor” might keep most of us from even trying.

The good news, though, is that if your dog wolfs a few down — and dog owners know some pups will eat literally anything — cicadas shouldn’t harm them. Just watch that they don’t choke from eating too many at once.

Kremlin Confirms Putin Transmitted Iran’s War Resolution Plan to Trump

The Kremlin says Putin relayed Iran’s proposal for ending the war to Trump, while Trump announced a Russian diesel supply deal that drew sharp criticism from Zelenskyy.

Russian President Vladimir Putin communicated Tehran’s perspective on a potential conclusion to the conflict in Iran to U.S. President Donald Trump, according to Russian state media reports on Saturday.

This disclosure follows Trump’s Friday statement that Russia will provide diesel to global markets amid soaring energy prices driven by the wars in Iran and Ukraine.

Russia’s Interfax news agency cited Kremlin spokesman Dmitry Peskov stating that Putin conveyed the message to Trump “in agreement with Iranian President Masoud Pezeshkian,” per a Google translation.

Additional Russian media accounts indicate Putin spoke with Trump by phone after meeting Pezeshkian on the margins of a summit in Turkmenistan.

Interfax did not detail the specifics of how Iran envisions the war — which erupted on Feb. 28 with U.S. and Israeli airstrikes on Iranian targets — reaching an end.

The White House did not immediately respond to Verum’s emailed request to confirm the reported conversation between Putin and Trump.

Russia supply deal

Trump announced Friday that Russia will deliver more than 4 million tons of diesel to the global market under an arrangement he said he agreed with Putin during a phone call.

Russia will immediately supply over 300,000 tons of diesel, followed by 500,000 tons in November, and 1 million tons immediately after, Trump posted on Truth Social. Moscow will then provide another 3 million tons of diesel contingent on the condition of Russia’s refineries, Trump added.

The Treasury Department temporarily waived sanctions on Russian diesel through April 2027 under a general license issued Friday.

Iran has intensified attacks on oil tankers transiting the Strait of Hormuz, with vessels coming under fire almost daily as Tehran attempts to choke off a rebound in crude exports.

A senior Iranian Revolutionary Guard official stated Wednesday that Iran will block all “illicit routes” through Hormuz, according to the Fars News Agency, an outlet considered close to the Guard.

The surge in tanker attacks coincides with crude oil exports from the Middle East rebounding in September to prewar levels, largely because the U.S. military escorted ships through Hormuz along Oman’s coast.

An interim agreement signed in June between the U.S. and Iran to pause hostilities to allow for negotiations quickly collapsed.

‘Gifts to Putin’

Ukrainian President Volodymyr Zelenskyy immediately denounced Trump’s diesel deal with Putin. Ukraine’s leader warned that easing sanctions without a commitment from Russia to de-escalate the war will only prolong it.

“Gifts to Putin will not bring peace or any benefit to the civilized world,” Zelenskyy said in a social media post. “Russia will ‘repay’ the diesel with further terror and perfidy. Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

Diesel prices have surged worldwide as Ukraine has pounded Russian refineries, forcing Moscow to ban diesel exports to global markets. Iran and its Houthi allies have also attacked refineries in the Middle East, further constraining fuel supplies.

Trump faces mounting political pressure to lower fuel prices ahead of the November midterm elections. Republicans confront competitive races in conservative strongholds like Iowa, where farmers feel the pinch of high diesel prices.

AI is Changing How Lawyers Work — and Putting the Billable Hour Under Pressure

AI is reshaping the legal industry by reducing the time needed for routine tasks, challenging the traditional billable hour model, and changing how lawyers learn and practice.

Artificial intelligence is now used by almost 90% of legal professionals in the U.K. and Ireland, and it’s putting one of the profession’s oldest conventions — the billable hour — under the microscope. That’s according to legal software company Clio’s U.K. & Ireland Legal Insights Report 2026.

It found that among firms using AI, almost 80% said they can handle more work without increasing resources, while over 70% said it cut costs by absorbing administrative work once done by support staff.

As a result, AI is challenging some of the assumptions on which the legal profession was built, forcing firms to reevaluate how their lawyers spend their time, how they charge for it and how new lawyers learn the ropes. You can’t charge 16 hours for something that takes 16 secondsNick Rowles-DaviesLexolent Some of the U.K.’s biggest firms are already putting this into practice.

A&O Shearman has worked with legal AI company Harvey to develop artificial intelligence agents for tasks, including reviewing loan agreements and analyzing regulatory filings, which it says can complete in minutes work that previously took several hours. Slaughter and May, meanwhile, has rolled out Harvey across all practice areas this year, including for regulatory research and document analysis.

Billable hour pressure The billable hour is central to the business model of many law firms, but when AI significantly reduces the time lawyers spend sifting through and drafting documents, the economics are no longer so straightforward. “You can’t charge 16 hours for something that takes 16 seconds,” Nick Rowles-Davies, founder and CEO of legal finance fund Lexolent, based in London and Dubai, told CNBC.

About one in five firms that have widely adopted AI report difficulty meeting billable-hour targets, according to Clio’s report. Globally, senior legal leaders expect the share of work charged by the hour to fall from 72% to 44% over the next two to three years, according to a Deloitte survey.

Routine work is the most exposed, Rowles-Davies said. “If you’ve got standard documents and you’re just putting in detail, then clearly that’s an automatic process.” But complex legal work still requires human judgment, he added, particularly when interpreting AI output and determining the right strategy for a client.

AI and workloads

Whether AI efficiencies ultimately make lawyers’ working lives better may depend on what firms do with the time they get back. Clio’s report found that 51% of legal professionals work evenings, but only 32% want to, while 22% work weekends compared with 11% who would choose to.

Joshua Lenon, Clio’s New York-based lawyer-in-residence, believes some lawyers are already seeing the benefits. “Lawyers [are] telling us that their day is getting better,” Lenon told CNBC, as AI becomes more commonplace.

“People are really looking at these tools and saying, ‘This is making work better.’”

Trump’s diesel agreement with Putin accused of contradicting Russia sanctions law

Ukraine President Volodymyr Zelenskyy said in a searing statement that the U.S. easing sanctions on Moscow “plays into Russia’s hands.”

President Donald Trump’s Friday announcement that Russia will supply diesel fuel to the global market marked an apparent pivot from recent efforts to pressure Moscow to end the Ukraine war by targeting Russian energy exports.

Trump claimed the move, unveiled with less than a month left in an affordability-focused midterm election, would swiftly bring down record-high diesel prices.

But commentators and critics were quick to highlight contradictions between the new policy and prior efforts by the U.S. to clamp down on Russian oil sales.

Those efforts most recently included the enactment of the Lindsey O. Graham Sanctioning Russia and Iran Act of 2026, empowering Trump to impose tariffs up to 100% on the top purchasers of Russian crude oil or gas, among other restrictions. Trump signed the bill into law just three weeks ago.

“Congress just passed a law giving Trump the power to impose new tariffs on major buyers of Russian oil & gas,” Scott Lincicome, vice president of the libertarian Cato Institute, said on X after Trump’s Friday announcement.

“Can America tariff America?” he quipped.

Sen. Richard Blumenthal, D-Conn., a member of the Senate Ukraine Caucus, accused Trump’s latest move of being “directly contrary to Congress’s intent in our bipartisan sanctions bill.”

Peter Harrell, visiting scholar at Georgetown University Law Center’s Institute of International Economic Law, in an X post said that the relaxation of Russian diesel restrictions “pretty much proves the point that the Graham Russia Bill was not going to force the Trump Administration to increase economic pressure on Moscow.”

Some of the criticism crossed party lines.

“Through the Lindsey O. Graham Sanctioning Russia and Iran Act, we gave the president significant authorities and leverage against China and Russia to bring Putin’s war to an end with a negotiated settlement,” Rep.

Michael McCaul, R-Texas, said in an X post. “Unfortunately, while I understand the desire to bring down diesel prices, I am concerned the lifting of sanctions on Russian oil will only fund the Kremlin’s war machine—emboldening more violence and destruction, as we have seen in recent days,” McCaul said.

The White House did not immediately respond to CNBC’s questions about the diesel agreement with Russia.

Less than a year earlier, the Trump administration slapped sanctions on multiple Russian oil companies in response to what it called “Russia’s lack of serious commitment to a peace process to end the war in Ukraine.”

Trump also had previously slammed NATO allies for continuing to buy Russian oil. In a September 2025 Truth Social post, he wrote, “the purchase of Russian Oil, by some, has been shocking! It greatly weakens your negotiating position, and bargaining power, over Russia.”

Later that month, Trump again harangued world leaders for doing business with Russia.

“They’re funding the war against themselves. Who the hell ever heard of that one?” he said in a speech at the United Nations General Assembly. “They can’t be doing what they’re doing. They’re buying oil and gas from Russia while they’re fighting Russia.”

Trump announced the diesel deal in a Truth Social post Friday afternoon after what he described as a “highly successful discussion” with Russian President Vladimir Putin.

Under the agreement, Russia will immediately supply more than 300,000 tons of diesel, then another 500,000 tons in November, followed by 1 million tons “immediately thereafter” and 3 million more depending on refinery conditions, Trump wrote.

The Treasury Department soon after said that Trump directed the Office of Foreign Assets Control to immediately issue a “temporary general license to allow the supply of Russian diesel to the global market.” OFAC specified that the sanctioned transactions will be authorized for about six months, until April 7.

Russia seemed to celebrate the move. “Russia-US cooperation on diesel and energy will benefit the world,” an X account associated with Putin’s economic envoy Kirill Dmitriev said in response to the announcement.

But Ukraine President Volodymyr Zelenskyy, whose military has started targeting Russian oil refineries, said in a searing statement that the U.S. easing sanctions on Moscow “plays into Russia’s hands.”

“Any easing of sanctions against Russia without a clear and lasting de-escalation agreement with Russia is an obvious weakness,” Zelenskyy said. “Allowing Russia to sell petroleum products is an investment in a war that must be ended, not prolonged.”

“We count on America’s fair support for our defense of life, for our defense of people in Ukraine – and on the United States having a correspondingly strong conversation with Russia,” he said.

“A strong one, not a weak one,” he added.

Trump thanked Putin later Friday afternoon for enabling “massive amounts of oil” to come to the U.S.

“We need oil for the world, and this is diesel, which is what we need, so we’re very happy to get it,” Trump told reporters before heading to Syracuse, New York.

The Trump administration has previously eased some Russian energy sanctions temporarily, though more narrowly than Friday’s announcement.

Earlier this year, in an attempt to stabilize markets after the start of the Iran war, the Trump administration issued limited, 30-day waivers allowing countries to buy sanctioned Russian oil that was already in transit.

But some interpreted the latest move as a more significant step.

“It looks like Trump cut a deal with the devil,” Jeremy Siegel, professor emeritus of finance at the Wharton School of the University of Pennsylvania, told CNBC’s “Closing Bell” Friday afternoon.

“It’s not a permanent solution at all. It’s sort of a short-term Band Aid,” Siegel said. “And cutting back on or eliminating sanctions on Russia for the invasion in Ukraine, I think, is a very unfortunate consequence.”
