Sampling comments: "we defined three strata of decreasing urbanization. We overlaid a grid of 500 × 500 m cell size... We then stratified grid cells into the three strata based on their pro- portion of built cover" namely urban, suburban, and peri-urban, and then "defined 45 sampling sites, by randomly selecting 45 grid cells (15 cells within each zone; Fig. 1)... Butterflies were recorded along fixed transects of 300m length, walking at a constant pace, within 5 m to the side (2.5 m each side)... lasting 30 min on average. Each of the 45 sites was sampled three times between April and June 2015 at approximately monthly intervals... Individuals were captured with a hand aerial net and re- leased after identification"
