Means of courtship latency (in seconds), frequencies of wing vibrations and of attempted copulations (as numbers per seconds), and number of matings are presented in the table. Males that never courted were not included in the estimates of mean courtship latency, and their numbers are shown parenthetically. Mann-Whitney U and Fisher's exact tests were used to estimate the statistical significance. * P < 0.05.
