Once soil temperature hand 64 degrees F , folks inhabit inseveral U.S. stateswill be in for a delicacy — or a horror show depending on their point of view . It ’s nearly time for “ Brood X ” periodical cicadas(Magicicada septendecim)to emerge en masse throughout Indiana and in part of Illinois , Ohio , Michigan , Tennessee , Georgia , North Carolina , Virginia , West Virginia , Maryland , Washington D.C. , Delaware , New Jersey , Pennsylvania and Connecticut .
The last time they made an appearance was a whopping 17 years ago . found in Bloomington , Indiana , at the meter , Keith Clay experienced “ Brood X ” for himself in 2004 and 1987 .
“ Ninety - nine percent of the lifecycle is below primer where you do n’t see them . But when they do out of the ground it ’s pretty awful , ” he says .
Clay is an Indiana University Department of Biology distinguished professor emeritus . He has since moved to New Orleans to chair the Department of Ecology and Evolutionary Biology at Tulane University .

Billions and Billions
The 17 - year cicadas will number in the billions — and they ’ll make a real racket . “ If you heard it in 2004 , it ’s kind of a skill fiction - y , alien - sounding thing , ” Clay describes . “ It ebb off and flow and can get louder and louder . It ’s incredibly vivid and then it die down and then it start up again . ”
They ’ll make an belief in other way during the few weeks that they drop above land . “ We had a wienerwurst that just stop deplete his food because he was eating so many cicada , ” corpse recalls .

detent , bozo , chickens , bomb and other livestock positively screw chowing down on theedibleperiodical cicada . So do people with comparatively adventurous palates . ( Some say cicadas taste like Asparagus officinales . Others suggest they ’re more like seafood . )

There aresome caveatsthough . People and pets with shellfish allergies might have adverse reactions . The turgid , boisterous insects could be a choking hazard , too .
Wild animals also eat their share . If you live in a Brood X state and you ’ve noticed more mole natural action latterly than you ’re used to , 17 - yr cicada may be just under the surface .
“ One of the early warning signal [ for cicada egress ] is mole activeness in lawn , ” Clay explain . “ you’re able to see these mole hills where the soil is piled up and they form these underground runways . The moles are gorging on these cicada nymphs below ground … . It is a lot of food for brute that forage below ground like breakwater do . ”

‘Parasites on Trees’
Because there are simplyso many17 - year cicala , far-flung predation does n’t seem to slow the specie down . Still , if you have young tree , you just might bid that something could stop the insects .
“ They ’re basically sponger on trees , ” the Great Compromiser notes . “ They spend 16 twelvemonth and 11 calendar month feeding off of the root systems of trees . ”
And after they emerge ? “ They go up up something and molt to the adult stage , ” he continues . Adult male then head for crown to call to and subsequently appeal likely mate . And , for their part , adult female lay their eggs inside humble tree branch .
Usually , they choose sprig that are about the size of it of a pencil . They ’ll puncture these with their ovipositor and leave behind rows of testis . Upon hatching , the vernal cicadas will burrow deep into the soil for the next 17 age .
Limiting the Damage
If you have very young trees you desire to protect , you might want to shield them using turgid tomato cages wrap up with very hunky-dory gauze or float row cover . expend landscape painting staples to secure the material over the tomato plant cage and into the priming .
Overlap separate opus of material as needed . Look carefully for any unprotected areas that a cicala might be able-bodied to sneak through .
Finally , if you had planned to install some new shrubs or sapling this spring , you might require to keep them potted up and stored safely indoors until the 17 - year cicadas have gone for expert .
“ By the end of June , it will be jolly much over , ” Clay says . Until 2038 , that is .
