The diversity level of the Coleoptera diurnal group is included in the low category because it has an average index value of 0.93, and the level of diversity of the Coleoptera nocturnal group is included in the medium category because it has an average index value of 1.34. The dominance index value is < 0.50, which indicates that no species dominates at each station, and the level of evenness is in the low to high category.
