What Type of Cicada Prepper Are You?

Filed under: Brood II | Magicicada | Periodical — Dan @ 5:23 pm

Are you preparing for the 2013 invasion of the Brood II Magicicada? If so, what type of cicada prepper are you?

Every type of prepper

If you’re visiting Cicada Mania, you’re probably trying to figure out when and where the Brood II cicadas will emerge. We have a page for that.

Once the cicadas arrive you’re also going to report them to Cicadas @ UCONN (formerly Magicicada.org), right? You’re also going to upload your photos and video to Facebook, Flickr, Twitter, YouTube, Vimeo, Pinterest, and Instagram, right? You’re going to tag your photos & video with appropriate tags like #BroodII, #Magicicada, and #17YearCicada as well.

Kid Scientist:

Kids will probably enjoy a cicada emergence more than any one group of people. Kids will want to learn, capture, collect, observe, photograph, draw, and write about cicadas.

If you want to learn about cicadas, there are many cicada websites, including Cicada Mania. There are also many books to read; ask your local library to obtain a few of them.

Capturing periodical cicadas is easy. Unlike other insects, these cicadas are slow and easy to grab when they’re on the ground on low on a tree. You can use a butterfly net if you want to catch one in flight. At night, when they first emerge, they are especially easy to catch. You can use a flashlight to spot them coming out of the ground, and shedding their skins on tree branches.

A portable butterfly pavilion is a great place to temporarily keep and observe cicadas. It’s a lot better than a coffee can with holes punched in the lid. Another good option is to use an old aquarium and turn it into a terrarium filled with natural objects, like tree branches. You can also wrap a tree branch with netting and place the cicadas inside that, and observe then in their natural habitat.

It’s good to have a magnifying glass or a camera with a zoom feature so you can observe the cicadas up close. If you have a camera, make sure you take plenty of photos and videos so you have something to remember about the cicadas.

Preparation list:

  1. Books and website links for research
  2. A flashlight to look for them at night
  3. A camera to take photos or video (a smart phone works just fine). Don’t forget to record their songs.
  4. A container or habitat to keep them in. Options include:
    1. A butterfly pavilion
    2. A terrarium
    3. A tree branch wrapped in fine netting
    4. The classic jar or tin can, for temporary storage
  5. A magnifying lens to see them up close
  6. Art supplies to draw or paint pictures of them

Amateur Cicada Researcher

Do you consider yourself a citizen scientist or amateur cicada researcher?

Prior to the emergence cicada researchers will monitor the temperature of the soil, using a ground thermometer, or a cicada tracker. They will also monitor the ground for dime-sized holes and cicada chimneys.

Each night the cicada researcher will check the ground at the foot of trees, waiting for the first emerging nymphs.

Once the nymphs start to emerge, the cicada researcher will record the location, take photos, video, and take notes on the number of cicadas observed. The researcher will also likely keep some samples of the cicada population.

After about a week, the male cicadas will be ready to sing. At this point, the researcher will record the cicada’s song with an audio recording device.

If you’re interested in collecting specimens, Bioquip has plenty of pinning and mounting, insect storage and netting supplies.

Massachusettes Cicadas has a good article on pinning cicadas.

Preparation list:

  • Measure the soil temperature: a Thermometer or Cicada Tracker
  • GPS Device: a device to tell your location, for use in mapping the emergence
  • Carry and Observe: butterfly pavilion; netting to wrap around a tree branch; a terrarium
  • Cameras: SLR cameras, video cameras, web cams, or even the camera in your smart phone
  • Computer: use your PC, tablet or smart phone to access the internet and record and report your findings
  • Pen and paper: just in case technology fails you
  • Supplies for pinning and storing specimens: get the supplies you need to preserve the specimens you keep
  • Chat with an expert: join the Yahoo Entomology-Cicadidae Group and chat with fellow cicada researchers and experts
  • Transporation: if you plan on helping to map the cicada emergence, you’ll need a bike, car or truck to travel around in. Bonus points, if the vehicle has a GPS device.

Nature Photographer:

My best tip for photographers and videographers is practice shooting at night. Most Magicicadas will emerge at night, and you don’t want to miss their emergence and amazing transformation from nymph to adult!

My trick is to point a flashlight beam at the cicada — that way the camera will see the cicada and you won’t spend a lot of time getting the camera to focus and flash in the dark.

Don’t forget your best macro lens as well, to get great up-close shots.

Preparation list:

  1. Your camera and equipment
  2. A tripod
  3. A macro lens
  4. A flashlight
  5. Practice shooting at night

Insect Gourmet:

Yes, a lot of people eat cicadas! People add them to stews, chili, or just fry them up with spices! People even add them sweets like cookies and ice cream! I like to call them “shrimp of the dirt”.

Cicadas, like all insects, are arthropods — just like lobsters, shrimp and crabs — so you might be able to prepare them using similar spices. Buttered, spicy cicada — nummers!

My tips: 1) You do not want to eat them if your neighbor has sprayed them with insecticide first; 2) I hear they’re tastiest when they’re still recently emerged and white (teneral); 3) Consult your doctor before eating any creature that has lived underground for 17 years.

I, personally, haven’t tried to eat a cicada. I’m not squeamish; I just like them too much to eat one, and I suffer from arthropod allergies (I get gout when I eat crustaceans), so I avoid trying cicadas.

More info on eating cicadas, including recipes.

Preparation list:

  1. Courage
  2. A strong stomach
  3. Recipes
  4. All the cooking implements and ingredients you need to cook ’em up
  5. A friend to call 911 in case you choke, have an allergic reaction or are poisoned by pesticide

Nervous Gardener:

Cicada Ron Swanson

I can sympathize with gardeners who are afraid that cicadas will damage or kill their plants. The good news is cicadas are not like true locusts. True locusts (which are actually a form of grasshopper) will strip plants of all leaves, flowers, and fruit. Cicadas only damage trees when they lay their eggs in branches. Typically a few of the weaker branches of a tree will die or weaken. The leaves turn brown, which is called flagging.

Cicadas are interested in trees. They can’t kill a large elm, maple, or oak. Where they can cause damage is to weaker ornamental flowering and fruit trees.

I’ve never personally experienced catastrophic cicada tree damage, but I’ve also never owned a flowering, miniature pear tree.

Preparation list:

  1. Consult with your local tree care expert. No sense in going out and buying a bunch of stuff, if you don’t need to.
  2. Netting. Placing netting around the branches of small trees will help keep cicadas off them.
  3. Insect Barrier Tape. Insect barrier tape keeps cicadas from crawling up the trunks.
  4. Foil. Again, to keep the cicadas from crawling up the trunks.
  5. Hose them down/off. Cicadas like dry and warm, not cold and wet.
  6. Manually pick them off like grapes.

I don’t recommend pesticides for three reasons: 1) collateral damage to other species of insects like honey bees, 2) I’m tired of hearing about pets that die from eating cicadas tainted with pesticides, and 3) I think cicadas are awesome, and I want to see them survive.

Clean Up Crew:

Be prepared to have to clean up dead cicadas in your yard. Depending on the number of cicadas in your neighborhood, you might need to clean them up with rakes and shovels, buckets, and wheelbarrows. They definitely stink when they start to rot, so you might want to bury them in a large hole, and cover the corpses with lime. I’ve heard of people composting their bodies as well.

Preparation list:

  1. Rake
  2. Shovel
  3. A bucket or wheelbarrow
  4. Lime
  5. A net, in case they end up in your pool

Cicada “Crowdsourcing”

Filed under: Brood II | Community Science | Magicicada | Periodical — Dan @ 5:40 am

What is crowdsourcing? Here is what the Wikipedia says:

Crowdsourcing is the practice of obtaining needed services, ideas, or content by soliciting contributions from a large group of people, and especially from an online community, rather than from traditional employees or suppliers. Often used to subdivide tedious work or to fund-raise startup companies and charities, this process can occur both online and offline.

There are two prominent cicada crowdsourcing efforts you can take part in!

First, there is the Cicada Tracker project:

The group Radiolab is hoping you’ll build what they call a cicada tracker. A cicada tracker will measure the temperature of the soil and report that back to Radiolab, to help estimate the arrival of the cicadas. Here is a short video about the project:

The Cicadas Are Coming! from Radiolab on Vimeo.

Throughout April there will be events where you can get to together with other cicada enthusiasts, and build cicada trackers. See their website for more details.

Second, there is Cicadas @ UCONN (formerly Magicicada.org).

Cicadas @ UCONN (formerly Magicicada.org) is a website where you can report and map cicada emergences in your area. I strongly suggest that everyone visits that site to report their cicada sightings. Your reports will be used to build new and better maps of the periodical cicada populations in the U.S.A.

When you visit their site, look for this icon, click it and enter your report:

Report Icon

Information needed for the report include the location (GPS coordinates, or simple street address), and what you observed: was it a nymph or adult, how many were there, etc. I think they’ll even have a Google maps interface to help you locate your sighting.

Periodical cicada Brood XIV (14) will emerge in 2025 in Thirteen States

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

Periodical cicada Brood XIV (14) will emerge in the spring of 2025 in Georgia, Kentucky, Indiana, Massachusetts, Maryland, North Carolina, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia. The last time this brood emerged was in 2008.

What, when, where:

What:

  • Millions of these:
    Adult, Nymph Molting
  • 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: Typically beginning in mid-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.

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

Periodical cicada Brood XIX (19) will emerge in 2024 in Fifteen States

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

Periodical cicada Brood XIX (19) will emerge in the spring of 2024 in Alabama, Arkansas, Georgia, Illinois, Indiana, Kentucky, Louisiana, Missouri, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, and Virginia. The last time Brood XIX emerged was in 2011.

Special note: Brood XIII will also emerge in 2024. While the two broods do not overlap, they come closest in the Springfield, Illinois area.

What, when, where, and why:

What:

Millions of these cicadas:
Adult, Nymph, Molting Cicada

  • Cicada insects with a 13-year life cycle.
  • Some people call them “locusts” but they are really cicadas. (Locusts are grasshoppers.)
  • Which species: All four 13-year species:
    • Magicicada neotredecim Marshall and Cooley, 2000. Range includes: AR, IL, IN, KY MO, & OK.
    • Magicicada tredecim (Walsh and Riley, 1868). Range includes: AL, AR, GA, IL, IN, KY, LA, MD, MO, MS, NC, OK, SC, TN & VA
    • Magicicada tredecassini Alexander and Moore, 1962
    • Magicicada tredecula Alexander and Moore, 1962
  • NOT the green cicadas that arrive annually.

Brood XIX has a 13-year cycle. It is interesting because it features both Magicicada neotredecim and Magicicada tredecim. These cicadas are very similar in song and appearance, but in areas where they overlap, Magicicada neotredecim alters its song to a higher pitch, which allows female cicadas to determine the species of their prospective mates. Visit Cicadas @ UCONN (formerly Magicicada.org) for more info on this behavior.

M. tredecim also have more orange on their abdomen than M. neotredecim.

Why: Why do they stay underground for 13-years? The prevailing research suggests they’ve evolved a long, 13-year lifecycle allowing them to avoid predators that would 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.

The most interesting 17 year cicada facts

The next major emergences are Brood XIII (17-year) and Brood XIX (13-year) in 2024. The last time these broods co-emerged was 1803.

If you have 18 minutes to spare, watch the video version of this article. Or save 18 minutes and just read it:

These are the 17 most interesting 17-year cicada facts (IMHO). All these facts apply to 13-year cicadas as well. Brood IX will emerge in 2020 in North Carolina, Virginia and West Virginia. Report 17-year cicada sightings using the Cicada Safari app available for Android and Apple devices.

  1. Names: People call these cicadas “locusts” but they are not true locusts — real locusts look like grasshoppers. The phrase “17 year cicada” indicates that they arrive every 17 years. The name “periodical cicadas” indicates that they arrive periodically and not each and every year. The scientific name for the Genus of these cicadas is Magicicada, and there are 3 types of 17 year Magicicadas: Magicicada septendecim, Magicicada cassini and Magicicada septendecula. This is a true locust:
    Locust
  2. There are 13-year cicadas too: there are 13 year cicadas too! There are four species of 13-year cicadas: Magicicada tredecim, Magicicada neotredecim, Magicicada tredecassini, and Magicicada tredecula. Broods XIX, XXII and XXIII feature these cicadas.

    Here’s a video that will help you identify the various species.

  3. Eye Color: Most 17 Year Cicadas have red eyes, but they can also have white, gray, blue , or multi-colored eyes
    White Eyed Cicada
  4. Fungus: The Massospora fungus infects Magicicadas, filling their abdomens and destroying their ability to reproduce. Often, their entire abdomen will fall off. The cicadas actually spread the fungus throughout their local colony via mating — the Massospora fungus is a cicada STD!
    Fungus
  5. They’ll attack land on you if you’re using a power tool or lawn mower. Cicadas think the sounds made by power tools and lawn maintenance equipment are made by cicadas. They get confused and will land on the people using the equipment! Pro-tip: cut your lawn in the early morning or near dusk when the cicadas are less active.
    Cicadas on Man
  6. Cicadas have five eyes: Cicadas have two, obvious, large, compound eyes, and three ocelli. Ocelli are three jewel-like eyes situated between the two main, compound eyes of a cicada. We believe ocelli are used to detect light and darkness. Ocelli means little eyes in Latin.
    5 eyes.
  7. People eat them: People eat them. You can barbecue it, boil it, broil it, bake it, saute it. There, uh, cicada kabobs, cicada creole, cicada gumbo, panfried, deep fried, stir fried. There’s pineapple cicada, lemon cicada, coconut cicada, pepper cicada, cicada soup, cicada stew, cicada salad, cicada and potatoes, cicada burger, cicada sandwich… that’s, that’s about it.
    Cicada Ice Cream
  8. Animals eat them: all wild animals and domestic pets will eat them. Dogs will gorge themselves until they choke. Squirrels will eat them like corn on the cob. Wild turkeys will grow fat and juicy on the cicada feast. Fish go crazy for them too — you can use them as bait, or use lures that mimic them.
  9. Cicadas “eat” tree fluids: Cicadas don’t eat solid foods — instead they use their slender, straw-like mouth parts to drink tree fluids.
  10. Cicadas pee: Yes cicadas pee, so wear a hat when walking under trees if that sort of thing bothers you. Cicadas drink tree fluids and then expel the excess fluid they do now need. People call it “honeydew” or “cicada rain”.
  11. That cicada sound: Only male cicadas make the sound they’re famous for. Males have organs on their abdomen called tymbals. Muscles pop the tymbals in and out, which creates the sound we hear. Males make different calls for different reasons, and each species has a unique sound. Females can make sound too — they flick their wings to respond to males. Read this article for more information.
    tymbals
  12. There are billions of them: there are literally billions of 17 year cicadas. Why? One theory suggests that a large number of cicadas overwhelms predators, so predators are never able to eat them all and cicadas, and many always survive to mate. This is a survival strategy called “predator satiation”.
  13. They damage wimpy trees: the biggest concern about 17-year cicadas is their potential to damage young trees. The truth is they will damage limbs on the wimpiest of trees, so if you have weak, pathetic, wimpy ornamental trees in your yard you should consider placing netting around the trees if the cicadas visit your yard. Also, you can try hosing them off with water, placing insect barrier tape around the trunk of the trees, or picking them off like grapes! Or, plant strong, beefy American trees — that’s what I would do. Cicadas actually benefit the health of trees by aerating the soil around the roots and trimming the weak or damaged limbs.
  14. Stragglers: Periodical cicadas that emerge in years before they are supposed to emerge are called stragglers.
    hipster cicada
  15. 17 and 13 are prime numbers. Scientist speculate that one reason why these cicadas emerge in 17 or 13 year cycles is because those are prime numbers. The fact that 13 & 17 are relatively large* prime numbers makes it difficult for predators to synchronize with them. (*Relative to the average lifespan of an animal.) Annual cicadas (cicadas that arrive every year) often have wasps specialized to prey on them; periodical cicadas have no such wasp because no wasp could evolve to synch with it.
  16. They use their color to warm up: Cicadas need to be warm to sing and fly around, but they’re cold-blooded. Their dark skin absorbs the heat of the sun, which helps to warm them up.
  17. 17 year and 13 year broods co-emerge every 221 years. Cicada Broods usually don’t overlap geographically, and it is very rare when they emerge in the same year. The next time Brood II (the brood emerging in 2013) will co-emerge with another brood will be in 2115 when it co-emerges with Brood XIX. You might need a time machine to see that happen.

Getting Ready for the 2013 Brood II Emergence

Filed under: Brood II | Magicicada | Periodical — Dan @ 12:01 am

Brood II will next emerge in 2030.

This page has not been updated since 2013.

Cicada Mania was started back in 1996, the last time Brood II emerged! The Spring of 2013 will be our first chance to see the children of the cicadas that emerged 17 years ago. Here is the basic information you need to know about the 2013 Brood II emergence.

Even though the emergence is 5 to 6 months away, it is never too early to begin planning… especially if you are a cicada maniac like me.

Magicicada septendecimThere will be plenty of cicadas on hand.

When will the Brood II cicadas emerge?

Brood II cicadas will emerge sometime in the Spring of 2013. They typically emerge once the soil 8 inches (20cm) below the surface gets to 64 degrees Fahrenheit (18º C). If we have a hot Spring, as we did in 2012, the cicadas could emerge in mid-to-late April. If we have a moderate Spring, the cicadas will wait until May.

Where will they emerge?

Brood II will emerge in parts of Connecticut, Maryland, North Carolina, New Jersey, New York, Pennsylvania, and Virginia.

Magicicadas won’t emerge everywhere in the states mentioned above. They might not exist in your town or neighborhood (particularly if trees were removed from your neighborhood).

More information about where the cicadas will emerge.

What is a Magicicada cicada?

Magicicada is a genus of periodical cicadas known for emerging in massive numbers in 17 or 13 year cycles/periods. The cicadas emerging in 2013 have 17 year life-cycles. Magicicada are also organized into broods. There are 12 broods of 17 year cicadas, and the brood emerging in 2013 is Brood II (Brood Two).

There are 3 species of 17-year Magicicada: M. septendecim (aka “decims”), M. cassini, and M. septendecula. The adults of all three species have black bodies with orange markings, and almost all have red-orange eyes (some have white or multi-colored eyes.

Here is some video and audio of 17-year Magicicada. This will give you an idea of what to expect:

Understanding Broods Using Analogies

Filed under: Magicicada | Periodical — Dan @ 8:11 am

Next year (2013) Brood II periodical cicadas will emerge along the eastern coast of North America (see our brood chart for where). You might find yourself wondering, “what is a brood“.

Here is a explanation of broods from Cicadas @ UCONN (formerly Magicicada.org):

All periodical cicadas of the same life cycle type that emerge in a given year are known collectively as a single “brood” (or “year-class”). The resulting broods are designated by Roman numerals — there are 12 broods of 17-year cicadas (with the remaining five year-classes apparently containing no cicadas), and 3 broods of 13-year cicadas (with ten empty year-classes).

The concept of periodical cicada broods can be difficult to wrap your mind around, so I wanted to present some analogies to help folks understand what a brood is. Generally speaking, it is important to not anthropomorphize insects, but if it helps you understand what a brood is, we can let it slide…

The Family Reunion analogy

Imagine that each brood is a family, and that each family has a family reunion every 17 years. They also, always, celebrate in the same location.

The next Brood II “family reunion” happens in 2013; their last reunion happened in 1996; and their next reunion will happen in 2030. They always have their reunion in CT, MD, NC, NJ, NY, PA and VA — its their favorite restaurant.

The High School Reunion analogy

Imagine that each brood is a high school class, and that class has a reunion every 17 years. They also, always, celebrate in the same location.

The next Brood III “high school reunion” happens in 2014; their last reunion happened in 1997; and their next reunion will happen in 2031. They always have their reunion in IA, IL and MO — their favorite hometown pub.

The Wedding Anniversary analogy

Imagine that a brood is a married couple, and they celebrate their wedding anniversary every 17 years. (Caution: if you’re a human don’t try celebrating your wedding anniversary only every 17 years – you won’t have a happy marriage).

The next time couple Brood IV celebrates their anniversary is 2015; the last time they celebrated their wedding anniversary was 1998; they next time they will celebrate their wedding anniversary will be 2032. They always celebrate in IA, KS, MO, NE, OK and TX — the restaurant where they first met.

Stragglers

Stragglers are periodical cicadas that emerge in years prior to, or after they are expected to emerge — typically 4 years earlier. This male Magicicada should have emerged in 2013, but instead he emerged in 2009 – four years earlier than expected.

We can extend these analogies to cover straggling.

If a periodical cicada shows up four years early to his family or high school reunion, he is not going to have much fun, because few, if any other periodical cicadas will be around to celebrate with. If Mr. Magicicada shows up early or late for a wedding anniversary, he is definitely not going to have any fun.

I think the High School Reunion works best.

Feel free to submit any other analogies in the comments…

2012 Brood I Wrap-Up

Filed under: Brood I | Magicicada | Periodical — Dan @ 8:36 am

Brood I, a brood of 17-year Magicicada periodical cicadas, emerged in the spring of 2012 in western Virginia, a small part of eastern West Virginia, and (expected by some, unexpected by others) in the Tri-Cities area of Tennessee.

The emergence in Tennessee caught some (myself included) by surprise, because it is not on Brood I maps, but folks in the Tri-Cities area say they expected it. Brood I is known as the Blue Ridge Brood because it exists along the Blue Ridge Mountains. The Tri-Cities area of Tennessee falls within the Blue Ridge Mountains, so the nickname of the brood works for Tennessee as well. I’m sure that there will be debate as to whether the Tri-Cities cicadas belong in Brood 1; we’ll know for sure in 2029.

Brood I emerged earlier than expected due to unseasonably warm weather in Virginia. On April 23rd, Barbara Dekorsey reported the following on the Cicada Mania Facebook page: “My kids and I saw periodical cicadas emerging on Blue Ridge Parkway MP 114.9, at the Roanoke River Trailhead (Roanoke, VA). It was wet and cool, and many of them were dead or dying with poorly formed wings.” Unfortunately, the moment when many cicadas began to emerge, the weather switched, greeting cicadas with wet, windy, cold weather, which resulted in cicada deaths and deformities due to harsh weather. Plenty of cicadas emerged unscathed, though, so the brood will live on.

Brood I is a small, but interesting Brood.

Ways to enjoy a periodical cicada emergence

Filed under: Magicicada | Periodical — Dan @ 12:30 am

Amazing things people do to celebrate a cicada emergence

cicada ice cream

Cicada Snacking. Probably the most unexpected thing people do during a periodical cicada emergence is eat them. Ice cream parlors have made cicada ice cream, pizza parlors have advertised cicada pizza, and people have created cicada recipe books. People and pets enjoy eating them; so do fish, so if you’re a fisherman, you can use them as bait. Would you eat a cicada? Maybe with BBQ Sauce?

Songs about cicadas. Over the years many artists have recorded songs about cicadas. There’s a music compilation called 17-Year Itch featuring songs about periodical cicadas…

… recently a musician called Dr. Chordate wrote a song called Periodic Cicadas. Would you write a song about a periodical cicada emergence?

Make some cicada arts and crafts. There are an amazing array of cicada arts and crafts for sale on Etsy, including jewelry, clothes, paintings, sculptures, and stationary. Would you make some cicada artwork? Would you sell it online? A lot of people have written books about cicadas. Would you write a poem, story, or an entire book about cicadas?

Cicada Activities

Report your cicada sightings to Cicadas @ UCONN (formerly Magicicada.org) so they can add your cicadas to their maps.

Don’t forget to photograph and video cicadas, and share them on Pinterest, Instagram, Flickr, YouTube and Vimeo. Blog or Tweet about your cicada experiences, and don’t forget to let us know about your cicadas on Twitter @cicadamania or Facebook.

You can try one of these cicada experiments and projects including, searching for rare white or blue-eyed cicadas, documenting a cicada’s life cycle, or keeping a cicada in captivity.

You can color a cicada with crayons or markers (PDF), or just draw your own.

Don’t forget to collect some cicadas and cicada parts. You can preserve cicadas a number of ways. You can preserve them in Lucite for an interesting paper weight. You can pin and mount cicadas; here is a how to article for pinning cicadas. Cicada wings and nymph skins don’t need preservatives. I keep them in small, magnifying boxes:
