Cicadas serenaded the dinosaurs

Filed under: Gene Kritsky | Nymphs — Dan @ 10:15 am

Apparently cicadas serenaded the dinosaurs! Entomologist and Mount St. Joseph professor Gene Kritsky shared the news today that cicadas lived as long as 110 million years ago during the Cretaceous period.

A quote from a press release:

New research has documented that cicadas, those noisy insects that sing during the dog days of summer, have been screaming since the time of the dinosaurs.

A fossil of the oldest definitive cicada to be discovered was described by George Poinar, Jr., Ph.D., professor of zoology at Oregon State University and Gene Kritsky, Ph.D., professor of biology, at the College of Mount St. Joseph in Cincinnati. The cicada, measuring 1.26 mm in length, was named Burmacicada protera.

Read the full Press Release on the MSJ website.

It looks a lot like a modern-day first-instar cicada nymph:

Update: Here’s a video news story about Gene’s fossil find.

I need a step-up my fossil collecting hobby. It looks like there’s some places in New Jersey to find fossils. Maybe I’ll find a cicada.

Brood III cicadas are emerging too!

Filed under: Brood III | Gene Kritsky | Magicicada — Dan @ 9:28 pm

Gene Kritsky wrote us to let us know that Brood III periodical cicadas are emerging in Iowa and Missouri.

Dan,

I wanted to let you know that I have received emails with reports of
emerging periodical cicadas in Iowa and northern Missouri in Brood III
territory. These cicadas would be emerging four years early similar to
the early emergences observed in 2000, 2003, 2004, and 2009.

Cheers,
Gene

It’s been an interesting year so far, with Brood III stragglers emerging 4 years early, Brood XIV emerging 2 years late, and Brood XIX emerging 1 year early.

Check our Brood Chart to see where the next batch of periodical cicadas might emerge.

BBC Filming in Mariemont

Filed under: Brood XIV | Gene Kritsky | Roy Troutman — Dan @ 9:56 am

I’m catching up on the photos Roy Troutman has sent me.

Here’s photos from a BBC photoshoot in Mariemont Ohio, taken on May 24th. The photos feature cicada expert Gene Kritsky.

2008 Cicada Temperature Study

Filed under: Brood XIV | Gene Kritsky | Magicicada | Roy Troutman — Dan @ 7:21 am

Roy Troutman sent me these photos of temperature loggers that allow cicada experts, like Gene Kritsky, to measure the ground soil temperature, and improve their formulas for predicting Magicicada emergences.

We [Gene Kristsky and Roy Troutman] buried 3 temperature probes & tied one on a tree branch for air readings. The temperature loggers will take a very accurate reading every 10 minutes & after the emergence has started in full swing Gene will dig them up & hook them to a usb cable & download all the data to his laptop for study. He [Gene] is trying to determine the exact temperature that they will emerge so he can fine tune his formula for calculating emergence times.

Last year Gene’s emergence formula calculator (try it!) did a good job of predicting the Brood XIII emergence, and the 2008 temperature study should only improve it.

You might be able to participate in the 2008 cicada temperature study. If you’re interested, contact Gene Kritsky.

An Interview with Gene Kritsky

Filed under: Books | Gene Kritsky | Magicicada | Periodical — Dan @ 4:26 am

Gene’s new book for 2024: A Tale of Two Broods: The 2024 Emergence of Periodical Cicada Broods XIII and XIX book by Dr. Gene Kritsky.

A Tale of Two Broods: The 2024 Emergence of Periodical Cicada Broods XIII and XIX

The 2006 Interview:

Gene Kritsky is one of the foremost and most accessible cicada researchers in North America. His excellent book In Ohio’s Backyard–Periodical Cicadas is a Cicada Mania favorite. Gene’s new book Periodical Cicadas: The Plague and the Puzzle is due out any day now. You should also visit Gene’s web site. Gene was kind enough to answer some of our questions — we hope you enjoy them:

Cicada Mania: There are a mind-boggling variety of insects in the world — why did you choose to focus your studies on cicadas?

Gene Kritsky: I am a student of history. I was first introduced to periodical cicadas by Frank N. Young at Indiana University. I immediately felt that there must be a wealth of information about periodical cicadas that had been overlooked through the years. It was mining that information, coupled with studying their biology that started it all for me.

CM: You have a new book titled Periodical Cicadas: The Plague and the Puzzle "emerging" in books stores soon. How does it differ from your previous cicada book In Ohio’s Backyard–Periodical Cicadas?

GK: The Plague and the Puzzle has a greater focus on history. It includes a long-lost manuscript written in 1716, the first stand-alone published work on periodical cicadas, a terminology timeline, and a review of what has happened in the past 104 years including, including new findings from my lab. In Ohio’s Backyard is a field guide for people wanting to experience the periodical cicadas. It contains activities for teachers and parents to help kids to better appreciate these insects.

CM: What makes Magicicada Brood X different from other emergences?

GK: Brood X is the largest of the 17-year broods. It has a long history going back to 1715. For me personally, I first studied Brood X in 1987 when it emerged in Cincinnati. It gave me the opportunity to set up some experiments that will finally come to completion. It is, therefore, like an old friend coming back to visit.

CM: Will all three 17-year Magicicada species (septendecim, cassini, &
septendecula) emerge this year?

GK: Yes, we are expecting all three species this year.

CM: Have you ever observed animosity between cicadas of different species? What cicada qualities make a male Magicicada more likely to find a mate? Does the guy with the loudest call, have the best chance of passing on his genes?

GK: I have not noticed animosity between the species, but have seen males of the same species compete for females by overlapping their calls. But we must be careful not to give the periodical cicadas human emotions. I think they are simply responding to a genetic cue, and doing what they do best. That being singing, matings, laying eggs, and dying.

CM: Do you think the mayor of Cincinnati should consider replacing the Flying Pig monuments with Cicada monuments?

GK: It is interesting that we have the same mayor this year as we did in 1987. This time, however, the city is getting into the emergence with a greater sense of fun. We are going to have a CD of cicada songs, cicada-free zones, cicada parties, cicada exhibits, t-shirts, jewelry, etc.

CM: Cincinnati is known for its chili restaurants. Know any good cicada chili recipes?

GK: I have not had them in chili, but they should be a nice addition. I personally like them battered and fried with a nice hot mustard sauce.
