Table 1 Butterfly abundance (N), species richness (S), Simpson’s reciprocal index (D), the Shannon–Wiener index (H′), the exponential of the Shannon–Wiener index (exp H′), Pielou’s evenness (J′), and species evenness (D/S) calculated for 3 months of butterfly surveys completed within the three areas of study. Coefficient of variation (CV) is given for each metric
