Here are some new photos from Roy Troutman that will give you a good idea of what to look for when searching for signs of cicadas in your yard:
This is a pair of Magicicada nymphs, much like you might find when gardening or turning over logs or stones in your yard.
See those beige globs of soil amongst the leaves and debris? Those are called cicada chimneys. They are a sure sign that a cicada nymph is below the soil, and will emerge in a few days or weeks.
Look closely at this picture and you’ll see holes in the ground. Those are holes that cicada nymphs have dug, and they’re another sure sign of where a cicada will emerge.
On May 1st we’ll start making predictions as to when they’ll start to emerge.
You can play an important role this year in documenting the Brood XIV 17 year cicada emergence. Brood maps are built using data from scientists and people like you. This year we have an opportunity to build a better Brood XIV map, but the scientists who collect the data will need your help.
Where to post your sightings
The two main web sites where you will be able to post your sightings this year are:
Both sites promise to feature interfaces that will easily allow you to enter your sighting.
In the Massachusetts area (and beyond): Massachusetts Cicadas (Jerry Bunker).
In the Mid-Atlantic region: Cicadas.info.
Gene Kritsky’s new site
Gene Kritsky’s new enhanced cicada site is now up here: THE MOUNT’S CICADA WEB SITE. The new site will feature much of the information you’ll need to know for 2008, including maps, a place to enter your cicada sightings, podcasts and more. You’ll want to bookmark this site.
Gene’s cicada temperature experiments
Gene is looking for folks to report where and when a emergence occurs in their yard/neighborhood/local park etc. “I would like to find several of your readers who are willing to let us know the day that cicada emerge in good numbers in their locations. I would like to test the emergence formula at several sites.” A good number would be an aggregation of approximately 25 cicadas on a single tree. Like the picture on this page. So, be sure to head to Gene’s site and make a report if the opportunity arises.
Nymphs in Long Island
Andrew from Long Island sent us photos of nymphs and soil with many cicada tunnels from Satauket L.I. Looks like 2008 will be a good year for Long Island cicadas.
Some random linkage

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.
John Cooley, one of the folks behind the Michigan Cicadas cicada site and the Cicada Central site now has a third site, which promises to have the best and most up to date Magicicada information. The new site is magicicada.org.
This site is designed to serve several purposes for 2008:
- It is a place where we are directing people to report cicada emergences, so that the records may be collected and geocoded.
- It’s got the best set of brood maps yet.
- It mirrors the information on Cicada Central.
- It will have better photos (the species photos for M. tredecim are second generation, but I’m working on even better ones).
Here’s some new photos from photographer and cicada enthusiast Adam Fleishman. As always, they’re great photos. If you can help ID the first two photos, we’d appreciate it.

Pia Ã–berg from Sweden took this cicada photo back in 2004 at Hotel do YpÃª in Itatiaia NP in Brazil. Thanks to Roy Troutman and cicada expert Allen Sanborn we were able to ID this pretty cicada as a Carineta diardi (Guérin-Méneville, 1829). In addition to Brazil, C. diardi is also found in Argentina.
Species: Carineta diardi (Guérin-Méneville, 1829)

What a fun way to start the New Year. Happy New Year cicada maniacs!
Here’s yet another wonderful cicada photo from David Emery in Australia: the Diemeniana euronotiana. The cicada is a mere 20mm in length, and they are now just out in the bushland around 1000m.
The Diemeniana euronotiana can be found in eastern NSW, south-eastern Victoria and Tasmania. They are most common in late November to January. (Moulds, M.S.. Australian Cicadas Kennsignton: New South Wales Press, 1990, p. 112)
Bron sent us this Green Grocer photo taken in Orange NSW Australia.
The scientific term for Green Grocers is Cyclochila australasiae. The come in other varieties such as the yellow colored Yellow Mondays and blue Blue Moons.
Cyclochila australasiae can be found in eastern Queensland, NSW and Victoria, and most emerge in October and November (Moulds, M.S.. Australian Cicadas Kennsignton: New South Wales Press, 1990, p. 61.).
