Update! New packaging for the Clustering Cicada fireworks (thx Roy). Find it here.
The Fourth of July should be fun this year at Roy Troutman’s place. Check out the Clustering Cicada fireworks he found.

Here is a video shot on the 4th of July of a mutli shot cake called the Chirping Cicada.
Elias Bonaros shared these photos of Neocicada hieroglyphica that he observed emerging in Riverhead, Long Island, New York, which is the north-most point of their range, as documented by William T. Davis.
They were taken today, July 13th, 2015.

Annette DeGiovine wrote an extensive blog post with many images and video of emerging Neocicada hieroglyphica. Check it out.

Is it true that someone has offered a reward for a white or blue-eyed Magicicada cicadas?
This was false and an urban legend until in 2008 when Roy Troutman began to offer rewards for living blue-eyed cicadas for scientific research. All cicadas were released, unharmed.
Important: Roy is no longer offering the reward as he has obtained the cicadas needed for his research. So, don’t bug him, unless you want to tell him that his photos and video are awesome.
White or Blue-eyed Magicicadas cicadas are extremely rare, so finding them can be difficult. I usually find one per emergence, and that is after looking at thousands of cicadas.
Speaking of Roy and White-eyed cicadas, here is a video Roy took of a White-eyed cicada:
And here’s a white and orange-eyed cicada taken by Roy:

Another straggler sighting, this time in Cleveland which should make it a Brood V one year straggler:
A Brood V straggler found by Matt Berger in West Virginia. See more photos of this cicada.
The emergence of Brood XXIII is well underway in the states along the Mississippi, and Brood IV should kick off in the west as soon as it stops raining every day. These aren’t the only Magicicada periodical cicadas emerging in the U.S. this year — some stragglers will emerge as well.
A straggler is a periodical cicada that emerges before or after the rest of its brood. Typically a straggler belonging to a 17 year brood will emerge 4 years early, but they might also emerge a year early, or a year late, or even 4 years late. This probability chart, details the probability of a straggler emergence.
In 2015 you might find the following stragglers:
- Brood XIII 17 year cicadas emerging 4 years early in OH, PA, WVA.
- Brood V 17 year cicadas emerging 1 year early in NY, OH, PA, VA, WVA.
- Brood XIX 13 year periodical cicadas emerging 4 years late in AL, AR, GA, IL, IN, KS, KY, LA, MO, MS, NC, OK, SC, TN, VA
- Brood XXII 13 year cicadas emerging a year late in LA, MS, OH, KY
Tyla MacAllister found a Brood XIX Magicicada straggler (emerged 4 years late) in Alabama!
From Roy Troutman: “I shot a video back in 1991 of a 17 year Magicicada cassini singing right on my hand.”

Cicadas spend most of their lives, as nymphs, underground. The large forelegs of cicada nymphs are adapted to digging through soil.

Here is a video of a rare white eyed magicicada. This is from a gene mutation that strepps the color from the cicadas eyes & also wings to some extent.

Cicadas breathe through apertures along the side of their body called spiracles. This video of a Tibicen by Roy Troutman shows the opening and closing of a spiracle.

Paul Krombholz has come through with an awesome guide to identifying Tibicens just after they have molted. Click the image below for an even larger version.
Notes on the species from Paul:
T. pruinosus [formerly T. pruinosa]—Newly molted adult has darker mesonotum (top of mesothorax) than the very common T. chloromera. Abdomen is a golden orange color. Older adult has dark olive on lateral sides of mesonotum, lighter green below the “arches”.
T. pronotalis (formerly walkeri, marginalis)—Quite large. The reddish brown color can be seen on the mesonotum of newly molted adult. Older adult has solid green pronotum (top of prothorax) and red-brown markings on sides of mesonotum. Below the “arches” the mesonotum color can range from carmel to green. Head is black between the eyes.
T. tibicen [T. chloromerus, T. chloromera]—has large, swollen mesonotum, quite pale in a newly molted adult and almost entirely black in an older adult. Individuals from east coast can have large russet patches on sides of mesonotum. The white, lateral :”hip patches” on the anteriormost abdominal segment are always present, but the midline white area seen in my picture is sometimes absent.
T. davisi—Small. This is a variable species, but all have an oversized head which is strongly curved, giving it a ‘hammerhead’ appearance. Newly molted individuals are usually brown with blueish wing veins that will become brown, but some have more green in wing veins. Some may have pale mesonotums that will become mostly black. Older adults vary from brownish to olive to green markings on pronotum and mesonotum.
T. figuratus [formerly T. figurata]—a largish entirely brown cicada. Newly molted adult has a pink-brown coloration with some blueish hints. Older adult has chestnut-brown markings and no green anywhere. Head is not very wide in relation to the rest of the body. The small cell at the base of the forewing is black.
T. auletes—a large, wide-bodied cicada. Newly molted adult is very green, but the older adult loses most of the green, usually retaining an olive posterior flange of the pronotum. The dorsal abdomen of the adult has a lot of powdery white on the anterior and posterior segments with a darker band inbetween.
Here’s an update for this article (8 years later).
This is a series of photos of a T. tibicen tibicen as it gets darker in color (photo by Cicada Mania). This cicada will retain the green color in its eyes and pronotum, but its back will turn almost entirely black.
