Densities are numbers/m²; sex ratio is the number of females/number of females + males.

Mating is the percentage of locusts mating. Values are means ± SE, and means in a column followed by different letters are significantly different according to the Tukey–Kramer HSD test. n = 7 in lek sites; n = 4 in other sites. The percentage data were arc-sine transformed before analysis.
