A Differences in insect species richness and B the abundance between the study sites for each trophic group and C proportional richness and D the abundance by trophic group between study sites. Asterisks indicate significant differences (p < 0.05). The results of multiple pairwise comparisons between the study sites were not significant (A and C). The error bars represent standard deviation. Site descriptions and locations are presented in Fig. 1
