Figure 1 Caption:
Raw occurrence data used in original analysis and flight period lengths by latitude for 4 datasets (A: Agriades glandon in N. America, B:Glaucopsyche lygdamus in N. America, C: Hesperia comma in Europe, D: Parnassius smintheus in N. America). Results for these species were presented in Fric et al. (2020) Figure 1 to demonstrate varied phenological patterns. Red dots represent observations used as both onset and termination in the original analysis. Marginal histograms show data density across latitudes (above the plot) and time of year (to the right of the plot).
