Watch a cicada transform

Filed under: Brood XIX,Magicicada,Video — by @ 9:05 pm

There are many interesting aspects of a periodical cicada emergence, including the length of time they spend underground, their massive numbers, their visual appearance, their amazing songs, and the variety of reactions people have to the cicadas. One of most amazing things you can witness during a cicada emergence is to watch cicadas emerge from the earth as nymphs, crawl up a tree, shed their skins, spread their wings and become adults.

Periodical cicadas will typically emerge over a period of several days. If you discover that cicadas have emerged in your yard by finding their skins (exuvia) or adult cicadas, chances are good more cicadas will emerge later that night. Filming a night-time cicada emergence is an excellent opportunity to use your HD Camcorders, Macro camera settings, and other technology you normally don’t get to use.

Here’s a guide to finding cicadas at night and ideas for filming them:

  1. Be prepared: Get your flash lights ready. Read the manual for your camera to learn about its night time settings, HD settings, Macro settings, etc. Make sure your camera is charged.
  2. Once the sun sets, head outside with your flash light and camera. Carefully walk around beneath the branches of trees, shining your flashlight towards the ground. Cicada nymphs live along the entire root system of a tree, so they can emerge 15 or more feet away from the trunk. Watch this video of cicada nymphs to see what to look for. Listen: you can actually hear them walk through the grass and up the bark of a tree.
  3. Once you’ve spotted nymphs, you can start filming. I usually aim my flashlight at them, and then let the flash in my camera light them up for the photo.
  4. Once a nymph crawls up the tree, and finds a part of the tree that it likes, it will emerge from its skin and become an adult. The process of completely becoming an adult takes several hours, so this is a good opportunity to make a time-lapse movie.

Here is a series of stills from a movie Roy Troutman made of an eclosing Magicicada:

Step 1: The nymph grabs hold of a leaf

Nymphs will crawl around until they find a place to grab hold of with their tiny tarsal claws. Usually they find part of a tree branch or leaf. Sometimes they find a car tire, a brick wall or a barbecue.

A nymph grabs hold of a leaf.

Step 2: The back of the cicada splits open, and the cicada pushes itself out.

The skin of the nymph splits open along the middle of its back, all the way up to its head. The cicada then pushes itself out back-first. You’ll notice that the cicada is white in color with two black spots on its back. At this point the cicada’s body is very soft — until a cicada’s body has hardened, we call them teneral, which means soft or tender in Latin.

The cicada pushes out of the nymph skin.

Step 3: With its abdomen anchored in the nymph skin, the cicada curls back, freeing its legs and spiracles.

The spiracles are the holes through which the cicada breathes. You’ll notice fine white strands connected to the nymph skin — those were once connected to the spiracles.

The cicada curls back, freeing its legs and spiracles.

Step 4: The cicada curls forward, grabs hold of its former skin, and frees its abdomen

The cicada then curls forward, and grabs hold of its former skin

Step 5: The cicada crawls away from its old skin and prepares inflate its wings

The cicada crawls away from its old skin.

Step 6: The cicadas wings fill with fluid and expand

The cicada inflates its wings using haemolymph, a blood-like fluid also used to transport nutrients in a cicada’s body.

The cicadas wings fill with fluid and expand.

Wings expand to their final shape

Now, watch the entire video:

Step 7: The color of the cicada darkens and its body hardens

Once the cicada has expanded its wings, the cicadas will turn their final color and their bodies and wings will harden. Once the body and wings are sufficiently hardened, they are able to fly and sing.

The “finished product” looks like this:

I hope you have the opportunity to watch a night time cicada emergence! It can be a lot of fun.

  1. I know this may sound a little bit crazy but, after watching this video my fear of cicadas has decreased so much… I know we’re about to get some here in Nashville because I’ve already seen a ton of random holes in the ground. I really want to go touch one but I hope they don’t end up flying in my face =P

  2. I had never heard of the cicada until recently. We live in Augusta, GA. We noticed a bunch of holes in our yard and then we saw all the empty shells. Had no idea what was going on. Once I found out about the cicada I am now totally infatuated with them. I think they are amazing. There are small woods behind our house and for the past three days they sing all day. I think they are amazing. Love this website with being able to view the transformation.

  4. I had the opportunity to see a cicada metamorphsis from the beetle hard shell to the insect itself, all white in color, with orange around the edge of the wings. The wings slowly opened, and it was soo incredible, and then with time turn color. I didnt know it was time for cicada’s this yr., but after talking to several people in other areas of the eastern Atlantic coast, they are in NC and up in PA from what i found out. In watching the video I was able to witness firsthand what the change was and it took about 2 1/2 hours to escape from its shell. Thanks to whoever made that video, because it was indeed very interesting.

  5. I live in West Blocton, Alabama and I work for Bibb County E-911. We started receiving calls about strange noises in the rural areas of the county about a week ago. We have now determined, thanks to your website, that the noises people are hearing are the songs of the cicadas. From what I’ve researched I believe they are Magicicada septendecim. My husband and I watched several emerge from the ground three nights ago. It was actually amazing! Today they are flying all around the yard. We are intrigued and trying to learn more about these magnificent insects. Thank you for your videos and other information.

  6. They are BIG bugs! We think it is cool when they come out of their old skin and the wings get bigger. It was clear and squishy. They get harder before they can fly. We wanted to see them fly and sing an amazing song.

  11. [...] night. Most Magicicadas will emerge at night, and you don’t want to miss their emergence and amazing transformation from nymph to [...]

  12. Listening to the sound of them all around me right now. A few fell from the trees onto the street, I moved them back onto the trees so they wouldn’t get hit by any cars. When I was 12 I was scared of the sound of them. I am 46 now,and I now appreciate and love seeing and hearing them. I live in Des Moines, IA and this is such a rare and beautiful treat of nature to get to experience for a second time in my life.
