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:

Aside from Brood X, what else is happening with cicadas in the U.S.

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.

Periodical cicada Brood X (10) will emerge in 15 states in 2021

Filed under: Brood X | Magicicada | Periodical — Dan @ 1:01 am

Brood X 2021

We expect them to emerge in Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Michigan, North Carolina, New Jersey, New York (extinct or nearly so), Ohio, Pennsylvania, Tennessee, Virginia, West Virginia, and Washington D.C. Report them with the Cicada Safari app. Use the hashtag #BroodX or #BroodXCicadas on social media.

LATEST NEWS:

What, when, where, and why:

What are these cicadas?

Billions of these insects:

Adult, Nymph, Molting Cicada

  • Black, orange and red Cicada insects with a 17-year life cycle.
  • Some people call them “locusts” but they’re really cicadas.
  • Which species: All three 17-year species, Magicicada septendecim, Magicicada cassini and Magicicada septendecula. How to tell the difference between the species.
  • NOT the green ones that arrive annually.

When will these cicadas emerge:

Typically beginning in May and ending in late June. These cicadas will begin to emerge approximately when the soil 8″ beneath the ground reaches 64 degrees Fahrenheit. A nice, warm rain will often trigger an emergence. Back in 2004, people began reporting emergences around May, 13th, but if the weather is warmer, it might start in late April. Update: in 2021, they started in Tennessee on 4/27.

Other tips: these cicadas will emerge after the trees have grown leaves, and, by my own observation, around the same time Iris flowers bloom:

More Location Tips:

Example Emergence Timeline

This is an example of a typical cicada emergence. The exact dates will depend on the weather and density of the emergence in your location. Hot weather means an early start and quicker finish to the season — cool weather means a later start, and a protracted season.

Example Emergence Timeline

Here’s an Excel version of the chart. Feel free to use it and adjust it to match your experience.

Or watch the video version:

Why do cicadas:

Why do they stay underground for 17-years? The prevailing research suggests they’ve evolved a long, 17-year lifecycle to avoid predators that can sync up with their lifecycle & emergence. Why are there so many?! Research suggests that their huge numbers allow them to overwhelm predators, so enough of them will live on to breed and perpetuate the brood.

Should you plant?

If you’re planting trees, wait until July. If your yard doesn’t get cicadas by the first week of June, it’s probably safe to plant in June. It’s the egg-laying that does damage. Talk to an arborist or tree expert if you’re actually concerned. I can’t answer your questions.
