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).
