From Roy Troutman: “I shot a video back in 1991 of a 17 year Magicicada cassini singing right on my hand.”

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).

How loud/noisy (in decibels) do periodical cicadas get?

Last Thursday Roy Troutman, Elias Bonaros and I traveled around central New Jersey, looking for cicadas. They were not hard to find. Elias found a location in Colonia that had a particularly loud Magicicada cassini chorusing center. Using my camera and Extech 407730 40-to-130-Decibel Digital Sound Level Meter, I recorded the calls of these cicadas and how loud they can get. The quality of the video isn’t the best because it’s a camera, not a video camera, but it is good enough.

Elias and Roy used finger snaps, mimicking the wing snaps of female cicadas, to trick the males into singing:

We placed the M. cassini directly on the microphone and got calls as high as 109 decibels, in this video:

There were a few M. septendecim in the area as well. A Magicicada septendecim goes from a Court II to Court III call as soon as it crawls on the decibel meter, in this video.

The cicada choruses in Central New Jersey have no doubt gotten louder since last week. Hopefully on Sunday I’ll get back out to Central Jersey or Staten Island and make some recordings.
