We used non-parametric estimators (second-order Jackknife
and Chao 2) to estimate the total tiger moth richness of
the study area. Rarefaction was used to compare the richness
among the habitats (grassland, edge, and Araucaria forest), as
the sampling effort (taken as the number of individuals) differed
between the habitats. The abundance and proportion of
singletons were compared between habitats by ANOVA, and
dominance (Simpson index) using Kruskal-Wallis tests.
