Why do cicadas make noise?
Male cicadas produce calling sounds using vibrating membranes. The sound helps attract females.
What do cicada nymphs eat?
Nymphs live underground and feed on plant roots before emerging and climbing up to molt into adults.
Do all cicadas emerge every 17 years?
No. Periodical cicadas have 13- or 17-year cycles. Annual cicadas are seen each year, though an individual may spend several years underground.
Try one observation
Look for a hollow cast skin on a trunk. Photograph it in place and note its height and nearby vegetation.
Observe without handling or collecting. These clues are a starting point, not a confirmed identification.
