  1. Observed parasitism rates are given for each study site for all sample years combined, with the yearly observations for each site given below the site summary rows. The overall totals for all sites and years combined are given at the bottom of the table. ‘Infected’ is the number of parasitized cicadas that were captured, ‘Uninfected’ is the number of unparasitized cicadas, ‘Total’ is the total number of cicadas captured, and ‘95% CI’ is the Wilson 95% confidence interval for the population estimate of the percentage of infected male cicadas. Refer to Figure 3 for study site locations.
