More crowd sourcing opportunities for cicada community scientists

I created a category for community scientist crowd sourcing projects. These are projects for you, the people, who want to help cicada researchers & scientists study cicadas.

Here are more ways you can help cicada researchers study cicadas:

Project 1:

Chris Simon and the Simon Cicada Lab need your help with a couple of projects:

We at the Simon Lab are anxious to get the word out that we are very interested in finding upcoming Brood II locations with lots of flagging (broken branches and wilted stems that should turn brown in late June or July or sooner down south).

When cicadas lay eggs they cause some damage to tree branches called flagging. It is easy to spot the brown patches of leaves. The Simon Lab want your sightings of flagging come the end of June and July.

A form to submit your sightings will be available soon.

flagging

Project 2:

Also we need to continue to crowd source locations of spring stragglers from any brood in any year.

A straggler is a periodical cicada that emerges years in advance of the rest of its brood. Typically they emerge four years in advance. An example of this is the cicadas that emerged in Ohio this year. Please let us know if you see a periodical cicada outside the Brood II area.

You can probably use this form for that.

Next year (2014), folks in western New York state might see some stragglers from Brood VII (due 2018) for example.

This chart will give you an idea of when stragglers can be expected. The best bet is -4 years for 17 year broods, and +4 for 13 year broods.

Probability of Straggling chart from Chris Simon

I’ve added straggler probabilities to this brood chart.

Note to self: read Periodical Cicada (Homoptera: Cicadidae) Life-Cycle Variations, the Historical Emergence Record, and the Geographic Stability of Brood Distributions by David Marshall.

Future projects:

There will be at least one more major crowd sourcing project coming soon. Stay tuned!

Finneytown Ohio 17 year Cicada Acceleration

Filed under: Brood VI | Gene Kritsky | Periodical Stragglers | Roy Troutman — Dan @ 11:10 pm

Roy Troutman, Gene Kritsky and his wife Jess witnessed a Magicicada emergence in Finneytown Ohio tonight. It is believed that this could be an acceleration of a new Brood VI, or an eight year acceleration of Brood X.

From Roy:

We had an unexpected emergence in parts of the Cincinnati area last night & I got some pics with my new Canon t4i. Gene [Kritsky] & his wife Jess came out to witness it as well. I would say hundreds emerged in a very small suburb of Cincinnati called Finneytown. This could be 4 year acceleration of the new brood VI that Gene has been talking about verifying in 2017 or 8 year acceleration of Brood X.

Brood XIV decelleration observed by Roy Troutman

Filed under: Brood XIV | Magicicada | Periodical Stragglers | Roy Troutman — Dan @ 9:53 pm

Here’s something neat. Roy Troutman discovered some Brood XIV Magicicadas emerging 4 years late in Ohio. That’s a “21 year cicada”. 🙂

Here’s the photos:

Gene Kritsky observed a similar unexpected emergence in 1995.

Look out for Brood II, Brood V and Brood XIX Stragglers

Filed under: Brood I | Brood II | Brood V | Brood XIX | Magicicada | Periodical | Periodical Stragglers — Dan @ 6:31 pm

When is a 2012 Magicicada not a Brood I cicada? When it’s a straggler.

A straggler is a periodical cicada that emerges in a year before or after the year they are supposed to emerge. Typically a straggler will emerge one or four years before, or one year after the year they should have emerged. Stragglers from Broods II (due 2013), Brood V (due 2016) and Brood XIX (backin 2011) are or will emerge this year in limited numbers.

Brood II is set to emerge next year in most of central Virginia (as well as CT, MD, NC, NJ, NY, PA), Brood V will emerge in four years in Virginia and West Virginia (as well as OH, PA), and Brood XIX emerged last year in a few areas of Virginia (as well as AL, AR, GA, IL, IN, KY, MO, MS, NC, OK, SC, TN).

Stragglers present a challenge for people tracking the Brood I emergence because Brood II, Brood V and Brood XIX stragglers will emerge in the same states as Brood I cicadas. Brood II and Brood V overlap Brood I in some places.

Here is a comparison of the I,II & V Broods. The black dots represent where the cicadas have emerged historically.

Here’s a map of Brood XIX in case you are curious:

Visit Cicadas @ UCONN (formerly Magicicada.org) for more information on this phenomena, and report your cicada sightings while you’re there. Credit goes to the Cicadas @ UCONN (formerly Magicicada.org)’s Facebook post that reminded me of the stragglers.

Brood XIV Straggler in Ohio

Filed under: Brood XIV | Periodical Stragglers | Roy Troutman — Dan @ 7:02 pm

Roy Troutman found this Brood XIV Magicicada straggler in the Cincinnati Ohio area this weekend. This cicada emerged 2 years after it should have. Amazing.

Look out for Magicicada stragglers – cicadas emerging early

Filed under: Magicicada | Periodical Stragglers — Dan @ 5:08 am

Magicicada cicadas are emerging early across America! You might know them as periodical cicadas, 13 or 17 year cicadas, or “locusts”. When cicadas emerge early (or later) they’re called stragglers.

Chances are they’re from Brood XIX or Brood XXII:
– Brood XIX is set to emerge in AL, AR, GA, IN, IL, KY, LA, MO, MS, NC, OK, SC, TN, VA next year.
– Brood XXII is set to emerge in LA, MS in 2014.

If you see one of these cicadas, report them to Cicadas @ UCONN (formerly Magicicada.org). Cicadas @ UCONN (formerly Magicicada.org) records the location of cicadas and adds them to a map, for scientific purposes.

Magicicada septendecim photos

On Monday (Memorial Day) I was lucky enough to find a lone Magicicada septendecim brood II straggler in Metuchen, NJ. This is a male, and he was about 1.5 inches or 3.8 centimeters long.

Look for orange coloring between the wing and eye to identify Magicicada septendecim:

Cicadas have 3 tiny eyes called ocelli:

Thanks to Elias for noticing the coloration behind the eye that IDs this as a decim.

Brood XIV stragglers confirmed as well as Brood II

Filed under: Brood II | Brood XIV | Magicicada | Periodical Stragglers | Roy Troutman — Dan @ 9:08 pm

So, we already know that Brood II stragglers are emerging in places like North Carolina and Virginia. Brood II cicadas weren’t due until 2013, which means the Brood II cicadas emerging now are emerging 4 years ahead of schedule.

At the same time, Brood XIV stragglers are emerging in Ohio (Batavia, Ohio to be exact). Brood XIV emerged in full-force last year, which means some Brood XIV cicadas emerging now are emerging 1 year behind schedule.

If you compare the Brood II map and Brood XIV map you’ll see they don’t overlap. Hint: open each map in a different browser or browser tab and toggle between the two.

Here’s some pictures of the Brood XIV stragglers Roy Troutman found just tonight in Batavia, Ohio.

Brood II Stragglers Emerging in New Locations

Filed under: Brood II | Magicicada | Periodical Stragglers — Dan @ 5:48 am

John Zyla of Cicadas.info has a report of a Brood II Magicicada (decim) found in Hollywood, St. Mary’s Co, MD.

If you find a cicada make sure you report it to Cicadas @ UCONN (formerly Magicicada.org) (Dr. John Cooley), and if in the Mid-Atlantic region report it to Cicadas.info (John Zyla) as well.

I’m pretty psyched — looks like some Brood II stragglers might emerge in New Jersey.

Be on the lookout for Brood XIV stragglers?

Filed under: Brood XIV | Magicicada | Periodical Stragglers — Dan @ 6:23 am

Be on the lookout for Brood XIV stragglers. A few Magicicada that didn’t emerge in 2008 should appear in 2009! Keep your eyes and ears peeled.
