I WANT TO SWHO YOU THE NEW CICADA ROOM THAT JUST OPENED UP AND ITS A MIXTURE OF BOTH SCIENCE AND ART TAKE A LOOK ALL AROUND. THE WLSAL ARE PHOTOS TAKEN OF CICADAS AND THEIR VARIOUS STAGES AND THEY WERE PHOTOGRAPHED BY WHO ELSE BUT DR. GENE CHRISTY, SO WE TALKED TO HIM TODAY ABOUT THAT CIRCLE OF LIFE. STEVEN WAS TALKING ABOUT ANDE THAT BRIGHTER AND QUIETER DAYS ARE AHEAD FOR NOW. ITS FITTING A CICADA GREETS YOU WHEN YOU RING, DR. GENE. KRITZKYS DOORBL,EL BUT HE SAYS THOSE DAYS ARE NUMBERED. WERE ON THE DOWNHILL SWING RIGHT N,OW DR. KRITZKE SETS THE CATAS IN SUCH ENCOUNTERS OF THE FLYING KDIN SHOULD BE DONE BY JULY 1ST. ITS A CICADA. THATS THT'S INVOLVED. ITS NOT BOTHERSOME. THEYRE THEYRE WONDERFUL ANIMALS, VERY PERSONABLE .DR. CHRISTY SAYS THOUGH. CICADA SONGS.

AND YOU LOOK AT THE ABDOMEN IF THE ABDOMEN IS ALL BLACK LIKE THIS. WITHOUT ANY ORANGE ITS MAGISTICATEDAS CSIDY RIGHT NOW FEMALES ARE LAYING THEIR EGGS AND BRANCHES LIKE THESE DR. KRISTI SAYS ITLL TAKE SIX TO TEN WEEKS FOR NYMPHS TO HATCH DROP FROM TREESND A SCURRY INTO THE GROUND FOR ANOTHER 17 YEARS. WE'L SEE MANY OF THEM HAVE HATCHING FROM PROBABLY MID TO JULY INTO MID-AUGUST DR. CRITZY SAYS YOULL START TO SEE SMELL AND CLEAN UP MORE. CICADAS LITTERING DRIVEWAYS GUTTERS AND SIDEWALKS. OH THE SMELL GOES AWAY AEW F DAYS, BUT THEN THEYLL STILL BE THERE, BUT THEYLL THEYLL BY THE TIME FAL COML AROUND AND HERE AND THE NORMAL WEATHERING OCCURS.

SO WE HAVE THAT CICADA FORECAST FOR YOU COMING UP AT 6:00. Share Shares Copy Link Copy  Adult Brood X cicadas are slowly dying off, but another  albeit much less noticeable  emergence has yet to come. Brood X cicadas have reached their final chapter in the Cincinnati area. They're beginning to die off after their once-every-17-year emergence. They emerge periodically, in this case, every 17 years, to mate and ensure the survival of their species. After mating, males die. The females lay their eggs, and then they too die.Female cicadas make slits in small tree branches and usually lay 20 to 30 eggs in each slit. A female can lay 400 to 600 eggs in a lifetime.Expect most adult cicadas to die off by July 1, according to Dr. Gene Kritsky, one of the world's leading experts in cicadas. But Kritsky said the cicada nymphs will be noticeable a few weeks later. "The next things to watch for are the leaves on some trees turning brown and some ends of the branches dangling from the trees called flagging. That is caused by the egg-laying from the female cicadas," Kristy said.Cicadas have been laying their eggs for a few weeks now. As such, the hatching of those nymphs will take place over the course of a few weeks. Look for those nymphs to begin hatching between mid-July and mid-August, Kritsky said. Unlike their cacophonous parents, these nymphs will be much less noticeable, out in the open briefly before dipping beneath the soil. After the eggs hatch, it will climb out of the nest and literally jump to the ground. They have to get underground as soon as possible to avoid predators, Kritsky said. By New Years Day they will be 8-12 inches underground sucking on a tree root.ANOTHER ROUND IN 2025Theres always another brood around the corner, Kritsky said, with a smile on his face.And just as Brood X begins to fade out across the Cincinnati area, Kritsky said another brood of periodical cicadas is right around the bend, with tens of millions of bugs slated to again take over Cincinnati again.Cicadas form cohorts called broods, which arise en masse like clockwork on the same schedule. There are 15 established broods of periodical cicadas  some emerging every 17 years, and others emerging every 13.In 2025, Brood XIV will emerge from the ground, another brood of 17-year cicadas.In four years, well have Brood XIV emerging, Kritsky said. Brood XIV is our eastern Hamilton County brood. I received a few emails from people in Milford and Batavia saying, We didnt get any this year. Just you wait. Theyll be coming out in four years.This 2025 brood will be much more apparent on Cincinnatis east side, Kritsky said, their cacophonous mating song is loud enough to drown out a passing jet plane.Areas east and north of the city should expect numbers similar to what the west side saw during the Brood X emergence, Kritsky said, with some communities seeing locally heavy numbers of the bugs.A stretch from Mason and Loveland, all along the east 275 corridor area, and then going eastern into Brown and Clermont counties. Thats who will see the bigger numbers in four years. Theyll get pretty loud in those counties in 2025," Kritsky said.But wait. Theres more.Another 13-year brood is expected to emerge in Brown and Clermont counties  as well as 10 other counties in northern Kentucky  in 2027.Well have a lot of cicada fun coming in years to come, Kritsky said.But at least were not Chicago. Kritsky said that north-central Illinois will have quite the cicada show in 2024. Its a double-emergence that he, in particular, is looking forward to.Chicago, in 2024, is going to have an exciting year. Theyre going to have Brood XVII, which is a 17-year cicada, and Brood XIX, a 13-year cicada. That only occurs every 221 years!" he said.
