Please use the correct imagery for 17 year cicadas

Filed under: Identify,Magicicada,Periodical,Video — Dan @ 1:01 am

If you’re writing an article about the coming emergence of the 17-year periodical cicadas, please use the correct genus & species of cicadas.

The genus of all 17 year cicadas is Magicicada, and they are never green. The three species of 17-year cicadas are M. septendecim, M. cassini, and M. septendecula. They’re all black with orange wings and legs and red eyes (some exceptions, but they’re never green).

Wrong Cicadas:

If the cicada you use in your article is green, it isn’t a 17-year cicada. I repeat: if the cicada is green it is not a 17-year cicada.

The cicada at the top of the Wikipedia page for cicadas is not a 17-year cicada, it’s an annual cicada called Neotibicen linnei:

Cicada Christmas Lights 🎅🏼

I made cicada Christmas lights using some LED USB Christmas lights, and some plastic cicada whistles from Australia. The song of cicadas heralds the Christmas season in many countries in the souther hemisphere like Australia.

There is a cicada nicknamed the Kobonga Christmas Clanger in Australia (thx David Marshall and Kathy Hill ):

Time to start looking for signs of periodical cicadas

Filed under: Magicicada,Periodical,United States,Video — Dan @ 1:01 am

Depending on where you live, it might be warm enough for periodical cicadas to start moving around underground, or start digging tunnels to the surface and building cicada “chimneys” above their holes. Report cicada nymph or adult sightings to Magicicada.org so cicada researchers will know where they are.

What to look for:

1) Animals can hear the cicadas stirring underground, and will try to dig them up and eat them. Look for holes (about the size of a walnut or larger) made by animals digging for cicadas.

2) Look for cicadas under stones and slates. Some cicadas will burrow their way to the surface, but they hit a large stone or slate and can go no further.

If you find them in this situation, gently put the stone or slate back. They will usually find their way around the obstruction once the time is right.

One clue that a Magicicada nymph is not ready to emerge is their eyes are still white. Their eyes turn red/orange prior to emerging (a few retain a white/blue color).

3) Cicada holes are about the size of a dime. Cicada premptively dig holes to the surface and wait until the weather is nice enough for them to emerge. Sometimes you can see them down in the holes.

4) Cicadas form chimneys above their holes when the soil is moist or muddy. These chimneys might look like a simple golf ball sized dome or a structure over six inches tall.

Periodical cicadas typically won’t emerge until their body temperature reaches approximately 65 degrees Fahrenheit (17-19.5 Celsius1). Their bodies are warmed by surrounding soil, or warm water from rain. A good rule of thumb is, if the soil 8 inches(20 cm) deep is 65°, the conditions are good that they might emerge.

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.

Magicicada cassini calls, chorusing & responses to finger snaps

Filed under: Brood II,Magicicada,Periodical,Sounds,Video — Tags: — Dan @ 8:00 am

During the Brood II emergence in 2013, Elias Bonaros, Roy Troutman and I spent some time experimenting with coercing male Magicicada to call in response to finger snaps, which mimic the snap of a female cicada’s wings. This trick works fairly well with Magicicada, and can quickly be mastered once you work out the timing. Fingers, wall switches, and the zoom button on my Sony video camera do a good job at mimicking the snap of a females wings.

I also recorded their calls in terms of decibels to see just how loud they could get. They can get very loud, but not as loud as a rock concert (see this db chart).
