Festuca rubra populations significantly differed in constitutive defence (content of Si and total phenols), nutritional quality (content of C) and inducibility of defence (change in total phenols), but not in growth response to herbivory. Herbivores (larvae of the nymphalid butterfly Coenonympha pamphilus) survived better on populations from colder climate and better survival was generally related to lower Si content and lower initial plant size. We demonstrated population differentiation in both constitutive and induced defence against insect herbivory, which directly affected survival of a generalist herbivore. Our findings confirmed the expectation that plants from higher elevations are more prone to herbivory.
