Clustering of CHC for females. Principal components for relative peak proportion for all crickets, labeled by sex and female CHC categories generated through clustering analysis. Categories include cluster “F” (predominantly G. firmus females, n = 29), cluster “P” (only G. pennsylvanicus females, n = 23), and cluster “ML” (females with male-like CHC profiles, n = 32 for G. firmus and n = 40 for G. pennsylvanicus)
