Cicada Mania

Dedicated to cicadas, the most amazing insects in the world.

Cicada T-shirts

Brood X (Ten) is a brood of Magicicada (genus) periodical cicadas located in DE, GA, IL, IN, KY, MD, MI, NC, NJ, NY, OH, PA, TN, VA, WVA, and Washington DC. It has a 17-year life cycle. The next time the brood will emerge is 2021.

Be cautious and considerate when looking for Brood X cicadas

Filed under: Brood X | Community Science — Dan @ 6:34 pm

Brood X will emerge in 2021, and people will want to travel to see and hear them. Should you decide to travel to witness Brood X or any cicada emergence in the U.S., be cautious and considerate of the following:

Be respectful of private property

Periodical cicadas thrive in neighborhoods and campuses with old hardwood trees and grass lawns, as you’ll find in places like Princeton, New Jersey. Don’t traipse and trample onto private property without permission and always visit local parks, instead of neighborhoods, when possible.

Observe local laws and customs

This should go without saying: obey local laws. Do not: litter, trespass, speed, j-walk, etc. Don’t give cicada fans a bad name.

Be prepared to practice social distancing and to wear a mask, even if just as a courtesy. I noticed that even outdoors in public parks, people in New Jersey wear masks.

Do not bring Spotted Lanternflies home with you

Spotted Lanternflies are true bugs, just like cicadas, but they are very, very destructive pests and an “invasive species”. Like the Pennsylvania Department of Agriculture website says, they “cause serious damage including oozing sap, wilting, leaf curling, and dieback in trees, vines, crops and many other types of plants”! They kill the trees cicadas call home.

Pennsylvania and western New Jersey are loaded with Spotted Lanternflies, so if you travel to those states to see Brood X cicadas, make sure you check your vehicle and belongings for Lanternfly hitchhikers. Don’t bring them home with you. At this time of year, I believe they are still in their black phase.

And squash them all — for the good of the forest and cicadas.

More info at the USDA website.

Protect yourself from ticks

Long Island (NY), New Jersey, Pennsylvania, and nearby states are loaded with Lyme Disease carrying Blacklegged/Deer Ticks. I’ve known people who have Lyme Disease and it practically ruined their lives. Unfortunately, ticks are found in the same areas as cicadas, like parks, yards, and forests. The CDC website has tips for preventing tick bites on people that I highly recommend you read and follow their tips. I personally wear pyrethrum-treated clothes when outdoors in New Jersey.

Different types of Magicicada periodical cicada holes

Filed under: Brood X | Chimneys | Magicicada | Periodical — Dan @ 5:19 pm

Different types of Magicicada periodical cicada holes found in Princeton, NJ. Brood X, 2021. Generally speaking, their holes are about the size of a dime. You won’t see a spray or kickback of soil around the hole like you would when an animal is digging into the soil rather than coming out of it (cicadas are coming out).

Brood X Cicadas in Long Island? Let’s find them

Filed under: Brood X — Dan @ 7:09 pm

Cicada on LI

Brood X periodical cicadas will emerge this spring (May) in the eastern U.S. — hopefully in Long Island as well. Chris Simon asked me to post this on the site. Brood X cicadas were hard to find in Long Island on 2004 — so we really want to find so, and how Long Islanders can help. Report cicadas with the Cicada Safari app.

Brood X may have breathed its last breath on Long Island! Or maybe not. This year may in fact reveal localities that we missed in 2004. It may capture people’s imagination just like the hunt for the last Ivory-Billed Woodpecker in Arkansas or the last Tasmanian Tiger in Tasmania.

Brood X cicadas were previously found on Long Island and it is unclear whether they are extinct or not! We are hoping to advertise the Cicada Safari app to your readers so they can help us find Brood X.

Attached is the Newsday article from 2004 that describes the previous Brood X emergence. Sites include Shirley, and Connetquot River State Park Preserve in Oakdale (Northeast section), and Ronkonkoma.

This locality info for Long Island is from the appendix of Simon and Lloyd 1982, J. N.Y. Ent. Soc.

It documents the historical decline of Brood X on Long Island as follows…

1902: Davis (1920) quoted the eighteenth report of the N.Y. State entomologist (1902. p. 113) as follows, “The insects were observed… at Wantagh. Nassau Co., also between Massapequa and Amityville, between Sayville and Oakdale, east of Patchogue to Brookhaven and also to the north of Medford and Holtsville, and a small brood [sic] northeast of Riverhead, all in Suffolk Co.” Davis (1907) reported that although a friend had seen hundreds of exuviae of the 17 -year locust in Prospect Park, Brooklyn. he had only obtained three adults and he “attributed their scarcity to the English Sparrow.”

1919: The New York Times of June 17th, 1919 (p. 25:3) talked with farmers in the vicinity of Farmingdale, Bethpage, and Massapequa who reported thousands of cicadas doing damage to fruit trees and other hardwoods. Old residents claimed that 17 years before they were not nearly so numerous. Daviis (1919) recorded” 1 7 -year cicadas singing at Mastic, L.L during the first week of June.” In another publication (Davis 1920) he noted them as occurring on South Country Road just cast of Carman’s River, and in the woods just east of Patchogue; also from Wantagh to Farmingdale and as far north as Central Park on Long Island; finally, north and east of Massapequa railroad station.

1936: The New York Times (June 12, 1936, p. 4:7) reported that the cicadas were found “first in Carmen Ave., Farmingdale … since then the swarms have been reported at Massapequa, and all through Suffolk scrub oak along the Motor Parkway from Medford westward to Farmingdale.” They were also seen along the Sunrise Highway in Massapequa Park.

1970: Newsday (June 5, 1970, p. 12) lists two exact localities Skylark Drive (Holtsville) and Springdale Drive (Ronkonkoma). They explained that “officials of the State Conservation Department and County Agricultural Extension Service said … that they have received hundreds of complaints this month about the insects. Most of the calls have come from an area including Ronkonkoma, Holtsville, Islip, and Sayville. where the influx is concentrated.” The same newspaper (June 23. 1970) reported 17-year cicadas in Bohemia on eighth Street near the South Side Sportsman’s preserve. They must have been abundant because “50 Bohemia residents … signed petitions appealing for help to fight the alarming problem of swarming cicada locusts [sic].”

Other, more recent, records…

1987: Suffolk Co. Long Island. Chris Simon and her student Andrew Martin collected periodical cicadas at Bohemia Equestrian Park in Oakdale and in Shirley.

2004: Suffolk Co. Long Island. Bryn Nelson of Newsday reports that periodical cicadas, “made only cameo appearances this year — first in East Setauket and later in Connetquot River State Park Preserve in Oakdale….Particularly vexing is the sputter at Connetquot, which reported masses of cicadas in its northeastern section both in 1987 and in 1970. Gary Lawton, a regional environmental education coordinator for New York State Parks, reported hearing a few cicadas at the park about three weeks ago….But after a few days, the calling abruptly stopped.” Residents of Shirley near the South Shore of Long Island, who saw them in 1987, did not see an emergence in their yards in 2004.

Periodical cicada Brood X (10) will emerge in 15 states in 2021

Filed under: Brood X | Magicicada | Periodical — Dan @ 1:01 am

Brood X 2021

We expect them to emerge in Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York (extinct or nearly so), Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Washington D.C. Report them with the Cicada Safari app. Use the hashtag #BroodX or #BroodXCicadas on social media.

What are these cicadas?

Billions of these insects:

Adult, Nymph, Molting Cicada

  • Black, orange and red Cicada insects with a 17-year life cycle.
  • Some people call them “locusts” but they’re really cicadas.
  • Which species: All three 17-year species, Magicicada septendecim, Magicicada cassini and Magicicada septendecula. How to tell the difference between the species.
  • NOT the green ones that arrive annually.

When will these cicadas emerge:

Typically beginning in May and ending in late June. These cicadas will begin to emerge approximately when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger an emergence. Back in 2004, people began reporting emergences around May, 13th, but if the weather is warmer, it might start in late April. Update: in 2021, they started in Tennessee on 4/27.

Other tips: these cicadas will emerge after the trees have grown leaves, and, by my own observation, around the same time Iris flowers bloom:

More Location Tips:

Example Emergence Timeline

This is an example of a typical cicada emergence. The exact dates will depend on the weather and density of the emergence in your location. Hot weather means an early start and quicker finish to the season — cool weather means a later start, and a protracted season.

Example Emergence Timeline

Here’s an Excel version of the chart. Feel free to use it and adjust it to match your experience.

Or watch the video version:

Why do cicadas:

Why do they stay underground for 17-years? The prevailing research suggests they’ve evolved a long, 17-year lifecycle to avoid predators that can sync up with their lifecycle & emergence. Why are there so many?! Research suggests that their huge numbers allow them to overwhelm predators, so enough of them will live on to breed and perpetuate the brood.

Should you plant?

If you’re planting trees, wait until July. If your yard doesn’t get cicadas by the first week of June, it’s probably safe to plant in June. It’s the egg-laying that does damage. Talk to an arborist or tree expert if you’re actually concerned. I can’t answer your questions.
