Cicadas have three types of life cycles: annual, periodical, proto-periodical.

Magicicada nymphs found by Elias, part 2

Filed under: Elias Bonaros | Magicicada | Nymphs | Periodical — Dan @ 6:02 am

Continuing from part 1, Elias Bonaros did some digging and took these photos of first and second instar Magicicada periodical cicadas on a warm winter day (March 21, 2010).

Now you know what cicadas look like when they’re underground!

Generally speaking the ones with the bulbous abdomens are second instar, and the smaller ones with the less bulbous or not bulbous abdomens are first instar.

Have you every wondered what cicadas look like when they’re underground? Elias Bonaros did some digging and took these photos of first and second instar Magicicada periodical cicadas on a warm winter day (March 21, 2010). Magicicadas have 5 instars, or phases of development. Each phase has a slightly different appearance.

This is a probable second instar nymph of Magicicada septendecim (Periodical cicada) from the 2008 Brood XIV emergence. Dug up from beneath an oak tree. It was living approximately 4-6 inches from the ground surface. Temperature 70 degrees.

Check for first instar periodical cicada nymphs

Filed under: Eggs | Magicicada | Nymphs | Ovipositing | Periodical — Dan @ 4:26 am

It’s been about six weeks since the emergence of Brood VIII in Pennsylvania, Ohio, West Virginia and Oklahoma. Now (first week of August) is a good a time as any to check for periodical cicada nymphs that have hatched from eggs laid in branches. Once they hatch they’ll find their way to the ground, where they’ll find and begin feeding on roots for the next 17 years.

Look on branches where cicada laid their eggs.

Annual Cicada Season in the U.S.A.

Filed under: Annual — Dan @ 1:01 am

Annual cicada species are those that arrive every year (annually). In the U.S.A., each continental state has at least 4 species of cicadas. California as over 80.

Wonder which annual cicadas are in your area? Try our cicada species page. If you’re outside the U.S.A., start your search here.

Some guides for identifying Neotibicen & Megatibicen, a common genus of cicadas in North America:

Three other excellent resources include: iNaturalist (enter a cicada name, and find out when people find them), BugGuide (USA), and Insect Singers (for sounds).

Here are a small portion of the species that can be found in the USA:

My Brood VIII Report

Filed under: Brood VIII | Magicicada | Periodical — Dan @ 7:54 pm

This year Brood VIII periodical cicadas emerged in the Pittsburgh area, and I traveled to see and map them. Unfortunately, I only had 3 days, so I only saw the western side of the Brood.

Mating Magicicada septendecim

All things considered — including cool, cloudy weather (which cicadas don’t like as much as hot & sunny) and a very rainy spring — Brood VIII was the least impressive brood I’ve witnessed, in terms of the sheer number of cicadas. I hope no one in the Pittsburgh area takes offense to that statement — Brood VIII is your brood, and you should be proud of it. It is just that as we humans build more and more, and continue to alter the environment, the numbers of cicadas will steadily dwindle. and I think we’re seeing that happen to Brood VIII.

Here’s an impromptu map of the places I saw cicadas:

2019 Periodical Cicada Stragglers – Expect Them

Filed under: Periodical Stragglers — Dan @ 9:06 am

Where is everyone?

We expect some periodical cicadas to emerge earlier and later than expected this year:

  • Members of Brood IV, the Kansan Brood, should emerge in IA, KS, MO, NE, OK & TX. Brood IV last emerged 4 years ago.
  • Members of Brood XXIII, the Mississippi Valley Brood, should emerge in AR, IL, IN, KY, LA, MO, MS, & TN. XIX last emerged 4 years ago.
  • Members of Brood X are emerging, so far in the Virginia area, but they have the potential to emerge anywhere in DE, GA, IL, IN, KY, MD, MI, NC, NJ, NY, OH, PA, TN, VA, and WV. 2-year early emergences are rare, but it happens. Brood X is expected to emerge in 2 years.

We’re getting a lot of reports from the Anacostia area of Washington D.C. and Maryland.

Here’s an example of someone Tweeting about a Brood X “straggler” on Twitter.

Use the Cicada Safari App to report them.

Periodical cicadas are cicadas insects that emerge periodically, and not annually. In North America, there are 7 species of periodical cicadas, 3 of which have a 17-year lifecycle, and 4 have a 13-year lifecycle, and all 7 belong to the genus Magicicada. Here is a chart that shows where they are expected to emerge next. Magicicada regularly straggle — some emerge before or after they’re expected to.

Typically 17-year cicada stragglers emerge 4 years early, and 13-year cicada stragglers emerge 4 years late, but 1, 2 and even 8 year deviations are possible — see the probability chart.

At this point, most people question the use of the term “straggler” to define something that emerged early rather than late. If you’re uncomfortable using the term “straggler”, you can use the term “precursor” for cicadas than emerge earlier than expected. You might make up your own slang for them, like “deviant”, “pioneer” or “laggard” too.

Cicada Safari app for tracking Magicicada periodical cicadas

Filed under: Community Science | Gene Kritsky | Identify | Magicicada | Periodical — Dan @ 9:28 pm

Cicada Safari App Frequently Asked Questions:

Cicada Safari App

Who created the Cicada Safari app?

Who do I speak to when the app is not working?

Probably Gene Kritsky and the Center for IT Engagement is your best route. Be polite. The app has 250,000 users and only a handful of people to approve cicada sightings.

Who is Gene Kritsky?

Gene is the Charles Lester Marlatt of the 21st century. Gene is a periodical cicada expert, researcher & professor. Buy his latest book, Periodical Cicadas: The Brood X Edition, now.

How do I download the app for my Apple or Android device?

Choose wisely: Google Play Store or Apple App Store.

How many people have downloaded the app?

As of June 1st 2021, over 250,000 people have downloaded the app.

Can I access the app data from a web browser?

Yes, you can! See a map of sightings from the Cicada Safari app.

Does the app have a website?

Of course the app has a website. Here’s the website.

What can I do with the app?

Judging by screenshots of the app, it looks like you can 1) identify cicadas, 2) take a photo and share it, 3) map the location where you found it, 4) compete with other cicada scientists for the most cicadas found. Looks that way at least. The app lets you submit cicadas photos of any species.

I’m not in the United States, so what app should I use instead?

Try the iNaturalist apps.

I don’t want to use an app. Can I send reports via email?

Not that I know of, but you can always ask Gene Kritsky. Feel free to leave a comment on this website or the Facebook Cicada Discussion Group.

Is Cicada Mania affiliated with the Cicada Safari app?

Cicada Mania is not affiliated with the Cicada Safari app. Cicada Mania is not paid to endorse or promote it. We promote it because we like it.
