Antibacterial defense scores (PC3 of the PCA) in insects reared under different larval relative humidities. Immune scores are plotted against A, B growth duration and C, D adult longevity, before and after an immune challenge occurring when the insects were young (A, C) and when the insects were old (B, D). The lines represent linear regressions and 95% confidence intervals are depicted in grey
