Cicadas produce 1000 eggs in a year, of which about 300 will survive to adulthood.
Most fossil Cicadidae are known from the Cenozoic, and the oldest unambiguously identified specimen is Davispia bearcreekensis (subfamily Tibicininae) from 5956 million years ago (Mya)
Cicadas sometimes cause damage to ornamental shrubs and trees, mainly in the form of scarring left on tree branches where the females have laid their eggs
