Modular switches shift monarch butterfly migratory flight behavior at their Mexican overwintering sites.

Importantly, when all fall individuals that were tested in sunny conditions are considered, group-level orientation in the southwest direction is highly significant ( Figure 1 D; modified Rayleigh: n = 33, R∗(weighted r ) = 1.337, mean vector [MV] = 229.675°; p < 0.005).
