There was a significant latitude‐by‐photoperiod interaction for development time ( P = 0.009, F 1:2.48 = 56.7) and a marginally nonsignificant interaction for body mass ( P = 0.066, F 1:2.52 = 9.70), signifying genetic divergence along the direction of multivariate plasticity and local adaptation in the use of photoperiodic cues to program development (Supplementary Information 5).
