Superimposed nymph phenology from 2000 to 2014 field samples. Points represent nymph density for each sampling, in function of day and month of tick collection, regardless of year. The three vertical dotted lines represent mean dates for, from left to right, O10 (questing onset: 10% of peak density), PND1 (spring peak), and PND2 (autumnal peak)
