Fig 3 Geographic variation in head widths (mean ± SD) of Locusta migratoria adults collected at various latitudes. Top and bottom diagrams illustrate the phylogenetic origin (Tokuda et al. 2010) and number of generations per year (as shown in Fig. 2). Red and green symbols indicate females and males, respectively. r indicates the correlation coefficient within each zone (see Suppl. material 1: table S3). *, p < 0.05; **, p < 0.01. Data are based on Suppl. material 1: table S2.
