Tips for Documenting the Arrival of 17-Year Periodical Cicadas

The arrival of 17-year periodical cicadas is one of nature’s most fascinating and rare phenomena. These insects, belonging to the genus Magicicada, spend most of their lives underground as nymphs before emerging in massive numbers to mate, lay eggs, and then die within a few weeks. Documenting this event offers a unique opportunity for entomologists, nature enthusiasts, educators, and photographers to observe an extraordinary biological cycle in action.

If you want to capture and record the emergence of these cicadas effectively, this comprehensive guide will provide you with tips on preparation, observation, photography, data collection, and sharing your findings.

Understanding the 17-Year Cicadas

Before diving into documentation techniques, it’s essential to understand what makes 17-year cicadas special:

Life Cycle: They spend 17 years underground feeding on root sap as nymphs.
Emergence: After 17 years, synchronized broods emerge en masse.
Massive Numbers: Millions can appear in a single area.
Short Above-Ground Lifespan: Adults live only about 4-6 weeks.
Distinctive Sound: Males produce loud mating calls.

This natural event happens so infrequently that many people never witness it in their lifetime. Hence, capturing it accurately holds both scientific and cultural significance.

Preparing to Document the Emergence

Research Local Brood Information

Periodical cicadas emerge in specific broods with designated geographic ranges and scheduled years. For instance:

Brood X emerged in 2021 in the eastern U.S.
Other broods have different schedules.

To prepare:

Identify which brood is expected to emerge in your region.
Review historical emergence data from sources like university extension programs or cicada-specific websites.
Note the anticipated timing of emergence (typically late spring to early summer).

Gather Necessary Equipment

Depending on your documentation goals—photography, video recording, sound recording, or scientific observation—you’ll need appropriate tools:

Camera: A DSLR or mirrorless camera with macro lenses is ideal for capturing close-up details.
Smartphone: Modern smartphones can also capture quality photos and videos.

Tripod: Helps stabilize shots during long sessions or low-light conditions.
Microphone/Recorder: To capture cicada songs clearly.
Notebook or Digital Device: For taking field notes about observations.
GPS/Mapping App: To log exact locations of sightings.
Protective Clothing: Long sleeves and pants to protect against insects and rough vegetation.

Bug Spray: Optional but helpful for comfort.

Learn About Cicada Behavior

Knowing cicada habits will help you anticipate their movements:

They usually emerge at dusk or dawn when soil temperatures reach about 64°F (18°C).
Newly emerged adults climb nearby trees or plants to molt into their winged form.
Males start calling shortly after molting to attract females.
Females lay eggs in tree branches.

Familiarize yourself with these behaviors so you can time your documentation accordingly.

Observing and Recording Cicadas

Choose Optimal Locations

Cicadas tend to emerge in wooded areas with plenty of deciduous trees since females lay eggs in branches. Ideal spots include:

Forest edges
Parks with mature trees
Residential neighborhoods with large trees

Scout locations a few days before the expected emergence date.

Monitor Soil Temperatures

Emergence is often triggered by soil temperatures warming up. Use a soil thermometer to monitor local conditions. When it reaches around 64°F at about 8 inches deep, emergence is likely imminent.

Document Stage-by-Stage

Periodical cicadas go through several observable stages above ground:

Emergence from Soil: Nymphs tunnel out of the ground, usually at dusk or night.
Climbing Plants: Nymphs climb onto plants or tree trunks.
Molting: The skin splits open and the adult cicada emerges—this process can take several hours.
Adult Activity: Adults feed on sap, call for mates, and mate.

Egg Laying: Females cut slits in small branches to deposit eggs.

Try to document each stage if possible. This gives a full picture of their lifecycle phase.

Take Detailed Field Notes

While photographing or filming, keep a journal that records:

Date and time of sightings
Weather conditions
Number of individuals observed
Behavior notes (e.g., calling activity)
Location coordinates
Any abnormalities or interesting facts

These notes increase the scientific value of your documentation.

Photography Tips for Capturing Cicadas

Use Macro Photography Techniques

Because cicadas are relatively small insects (about 1 to 2 inches long), macro photography is essential for capturing fine details such as wing patterns, eyes, and exoskeleton textures.

Tips:

Use a macro lens or close-up filters on your camera.
Shoot in good natural light or use a ring flash for even illumination.
Focus carefully on the eyes or wings for maximum impact.

Capture Behavioral Shots

Try to photograph:

Nymphs climbing out of the ground
Molting process with split exoskeletons
Male cicadas singing on branches
Females laying eggs (look for twig damage)

These action shots tell a compelling story about their life cycle.

Use Timelapse Photography

Setting up a camera to shoot time-lapse sequences can show slow processes like molting or mass emergence events over hours or days compressed into minutes.

Photograph Sound Production

Males produce loud calls using specialized abdominal structures called tymbals. While you can’t capture sound visually, photos focusing on males singing—with open wings or raised bodies—illustrate this behavior.

Recording Cicada Sounds

The intense chorus of periodical cicadas is one of nature’s iconic soundscapes. To document it:

Use High Quality Audio Equipment

A directional microphone paired with a digital recorder will provide clear recordings without too much background noise.

Record Different Call Types

Males produce various calls such as:

Mating calls (steady buzzing)
Rivalry calls (aggressive bursts)

Capture samples of different sounds throughout the day to reflect behavioral changes.

Note Environmental Details

Record weather conditions like temperature and humidity since these affect calling intensity.

Sharing and Utilizing Your Documentation

Contribute to Citizen Science Projects

Many organizations track periodical cicada emergences through volunteer contributions. Sites like iNaturalist or local university entomology departments welcome:

Photographs
Audio files
Location data
Field observations

Your data can help scientists study population dynamics and environmental impacts.

Educate Others

Use your photos, videos, and notes to create educational content for schools, nature groups, or social media platforms. The more people learn about this rare event, the more awareness grows regarding insect life cycles and biodiversity.

Preserve Your Records Digitally

Organize your files meticulously with metadata tags including dates, locations, species identification if possible (e.g., Magicicada septendecim), and behavior descriptions. This ensures long-term usability for research or personal reference.

Safety Considerations When Documenting Cicadas

Although periodical cicadas do not bite or sting humans and are harmless overall:

Avoid disturbing their natural habitat excessively.
Be cautious when walking through wooded areas—watch for ticks or poison ivy.
Respect private property boundaries when observing in neighborhoods.

Following ethical fieldwork principles ensures both your safety and minimal impact on the environment.

Conclusion

Documenting the arrival of 17-year periodical cicadas is an exciting endeavor that combines biology, art, and citizen science. By preparing thoroughly, understanding cicada behavior, using appropriate equipment, and maintaining detailed records, you can create valuable visual and scientific records of this rare natural event. Whether you are a seasoned entomologist or a curious observer capturing your first emergence, these tips will help you make the most out of this extraordinary cycle that connects us intimately with nature’s rhythms every 17 years. Embrace patience and curiosity — and enjoy witnessing one of nature’s grandest spectacles!
