Different types of Magicicada periodical cicada holes

Filed under: Brood X | Chimneys | Magicicada | Periodical — Dan @ 5:19 pm

Different types of Magicicada periodical cicada holes found in Princeton, NJ. Brood X, 2021. Generally speaking, their holes are about the size of a dime. You won’t see a spray or kickback of soil around the hole like you would when an animal is digging into the soil rather than coming out of it (cicadas are coming out).

Cicadas will burrow up from the soil of the ground and keep going into the rotting wood of a rotten log! I had to roll the log over to see it.

Periodical cicada nymphs emerging at night

Filed under: Brood XIII | Magicicada | Molting | Nymphs | Periodical — Dan @ 5:29 am

One of the most fun periodical cicada experiences is watching thousands of nymphs emerge from the ground at night, and crawl to the nearest vertical surface (hopefully a tree) and begin to molt.

This is a video by Roy Troutman from 2007 of the Brood XIII emergence, specifically in Ryerson Woods in Illinois:

Here’s a time-lapse video, also by Roy, of a cicada nymph molting:

Magicicada wing flicks

Filed under: Magicicada | Sounds — Dan @ 7:59 pm

Female Magicicada cicadas do not sing, but they do make a sound by flicking their wings. These percussive wing flicks get the attention of male cicadas and it compels them to sing their court songs in response.

Here’s a video of a female cicada flicking her wings:

You can fool male cicadas into thinking a finger snap is a wing flick. Here’s a video of a male cicada calling in response to fake wing flicks:

Filed under: Magicicada | Periodical | Periodical Stragglers — Dan @ 9:21 pm

Aside from Brood X, what else is happening in terms of Periodical cicadas?

  • Expect some early-emerging cicadas from Brood XIV, showing up 4 years early. Brood XIV exists in Georgia, Kentucky, Indiana, Massachusettes, Maryland, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia.
  • There might be some 1-year stragglers form Brood IX. Brood IX is in North Carolina, Virginia and West Virginia.
  • There might be some 4-year stragglers from Brood VI. Brood VI is found in Georgia, North Carolina, South Carolina, and Oklaholma. And Ohio?Brood VI is a weird one.

70,000 Magicicada cicadas = one adult American?

Filed under: Magicicada | Periodical — Dan @ 11:12 pm

I was wondering how much an adult Magicicada weighs. According to Richard Karban’s paper “Transient habitats limit development time for periodical cicadas,” a female Magicicada septendecim weighs approximately 1.2 grams. (Karban, R. (2014), Transient habitats limit development time for periodical cicadas. Ecology, 95: 3-8. https://doi.org/10.1890/13-1518.1)

According to the CDC website, the average adult American human weighs 84051 grams.

That means the average adult weighs as much as 70,043 Magicicada cicadas.
