Why stay in a bad relationship? The effect of local host phenology on a generalist butterfly feeding on a low-ranked host

Table 2 Statistics of the OPLS-DA models used to investigate class discrimination (i) between vegetative plants used in the two larval rearing (V plants early vs late), (ii) of each plant developmental stage used in the oviposition preference tests over the season (V plants early vs late, R plants early vs late), and (iii) between plant developmental stage used in each of the oviposition preference tests (V vs R in Ovip early and late)

For each model are shown the number of component of the model, the variance captured by the model (R²X), the y-fit (R²Y), and the predictive capability (Q²). The significance of the OPLS-DA models were evaluated based on the p-value of the Cross-validation ANOVA, and the intercept obtained from the permutation test. R and V correspond to reproductive and vegetative plants, respectively
