Schematic view of a density curve of questing nymphs over one year, modified from Perret et al. [15]. Shown are parameters used for analyses: cumulated nymph density (CND), calculated as the integral of nymph density curve over the year; peak nymph density (PND) represents the maximal nymph densities in spring (PND1) and autumn (PND2); nymph peak (NP1 and 2) are dates linked to PND1 and 2, respectively. O10 represents the first day of the year at which nymph density reaches at least 10% of maximal density (PND1). This date was interpolated from the 2 closest field samples
