So the cicadas have arrived, guess that means its officially summer. I’m including a pic of an adult and the shell of a nymph (?) it came from (maybe, I think, Lol). Don’t know which kind of cicadas this is (how many years it spent under ground), but its out in Columbus, OH now.

Periodical Cicada: Brood X Straggler

Dear Amber,
This is a Periodical Cicada, and in your area, Periodical Cicadas normally remain underground for 17 years, leading to the common name 17 Year Locust, though Cicadas and Locusts are not related.  2017 is the year Brood VI Periodical Cicadas are due to emerge in Georgia and the Carolinas according to Cicada Mania.  For some reason, this year is also producing Brood X Stragglers and according to Cicada Mania:  “Brood X stragglers have emerged in Tennessee (around Knoxville), Washington D.C., Virginia (counties around D.C.), Maryland (counties around D.C.), Ohio (around Cincinnati), Delaware, Indiana, Kentucky, Pennsylvania, & New Jersey (around Princeton)! They are chorusing in many locations.”  Cicada Mania also includes this fascinating information:  “Note: because of the significant number of cicadas emerging ahead of time, this might be an acceleration event. Periodical cicada accelerations occur when a significant group of an established brood emerge in years ahead of the main brood, and sometimes the accelerated group are able to reproduce and create what is essentially a new brood. Brood VI was likely part of Brood X at one point of time1. We’ll have to see if the Brood X stragglers are able to survive predation, and reproduce in significant numbers to sustain future populations. They are certainly trying.”  The exuvia or cast off exoskeleton of the nymph is a nice addition to your submission.

hello, I was wondering if you could please let me know what kind of bug this is in the picture. I live in Baldwin, Maryland and I have seen this bug before I believe it sheds a shell of its skin. This one seems like it is getting bigger underneath so Im thinking it may be pregnant.

Periodical Cicada Exuvia: Brood X Straggler

Dear Michele,
This is the exuvia or shed exoskeleton of a Cicada, and considering your location and time of year, this is probably the exuvia of a Periodical Cicada, a Brood X straggler.  According to Cicada Mania:  “Brood X stragglers are emerging in Tennessee (around Knoxville), Washington D.C., Virginia (counties around D.C.), Maryland (counties around D.C.), Ohio (around Cincinnati), Delaware, Indiana, & Kentucky! These stragglers are emerging 4 years ahead of time. HOT weather this week will cause even more to emerge, and they may begin to chorus (synchronized singing) as well.”  Periodical Cicadas are erroneously called 17 Year Locusts.

I spotted this cicada today in Louisville, Kentucky. I saw the earlier post on this site saying some of the brood X are emerging early. Is this one of the early cicadas?

Periodical Cicada: Brood X Straggler from Kentucky

Dear Ann,
Because of your Kentucky location, we believe this Periodical Cicada is also a Brood X straggler.  According to Cicada Mania:  “Brood X stragglers are emerging in Tennessee (around Knoxville), Washington D.C., Virginia (counties around D.C.), Maryland (counties around D.C.), Ohio (around Cincinnati), Delaware, Indiana, & Kentucky! These stragglers are emerging 4 years ahead of time.”

Ed. Note:  When we learned the Periodical Cicadas from Brood X stragglers were emerging off schedule this year, we wrote to Susie who lives outside of the Washington DC area to see if they are emerging near her.

Our cicadas aren’t supposed to emerge till 2021, but we are being flooded right now. I’ve never understood why some broods have 13 year cycles, other broods have 17 year cycles. Is it possible that our population of Brood X cicada, which last emerged in 2004, is converting from a 17-year cycle to a 13 year cycle? Is there a precedence for this?

Periodical Cicada: Brood X straggler

Dear Divya,
Thank you for sending in your marvelous images and for posing such an interesting theoretical question.  First thing is that not all Periodical Cicadas are the same species.  According to BugGuide, there are at least seven species in North America, with three of them being on a 17 year cycle and four on a 13 year cycle.  More northern species have a 17 year cycle while southern species are on a 13 year cycle.  According to Cicada Mania, 2017 will see the emergence of Brood VI, but there is a note that reads:  “If you’re in VA, MD, DC, DE, IN, TN, & OH head over to our Brood X straggler page.”  There is a further note that reads:  “Brood X stragglers are emerging in Tennessee (around Knoxville), Washington D.C., Virginia (counties around D.C.), Maryland (counties around D.C.), Ohio (around Cincinnati), Delaware, Indiana, & Kentucky! These stragglers are emerging 4 years ahead of time. HOT weather this week will cause even more to emerge, and they may begin to chorus (synchronized singing) as well.  Note: because of the significant number of cicadas emerging ahead of time, this might be an acceleration event. Periodical cicada accelerations occur when a significant group of an established brood emerge in years ahead of the main brood, and sometimes the accelerated group are able to reproduce and create what is essentially a new brood. Brood VI was likely part of Brood X at one point of time1. We’ll have to see if the Brood X stragglers are able to survive predation, and reproduce in significant numbers to sustain future populations.”   We would not discount global warming as a contributing factor in the acceleration.  We are featuring your submission on our home page banner.

Brood XIX Periodical Cicada

Brood XIX Periodical Cicada

Dear Heidi,
According to the file data, this image was taken on May 9, 2011 at 11:50 AM.  That makes this Periodical Cicada a member of Brood XIX, or the Great Southern Brood, according to USA Today.  This brood has a 13 year cycle, as opposed to the 17 year cycle of more northern broods.  Also, it appears that the lower creature in your image is a nymph that has not yet molted, and not an empty exuvia.  Earlier this year, we sent out a request for images of Brood V Periodical Cicadas, but alas, none were submitted.
