This study was carried out 4 habitat types: Grass land, shrub, regenerating forest, and stream side. The total of 384 individuals ladybirds of 37 species and 21 genus were recorded. The genus Epilachna has the most species number with 8 species, consists 21.62 percent of total species
the next is Coccinela (5 species), Coellophora (3 species), Cheilomenes, Diomus (2 species). The other genera have only 1 species. This study supplement 12 species of 6 genus to the list of ladybird in Bach Ma National Park, of which 3 new recorded genera are Afissula, Diomus and Stethoros. The uncomon species have the most of species number in 3 habitats of Grass habitat (6 species), Shrubs (8 species) and Stream side (3 species). The regenerating forest has the most of rare species. The species richness index is highest in the regenerating forest (d=3.725) and lowest in Grass-plot (d=1.801). The eveness index is highest in Grass habitat (J'=0.9817) and lowest in regenerating forest (J'=0.9249). The diversity index is corresponding to the species richness index, it is highest in regenerating forest (H'=2.673) and lowest in Grass habitat The most of ladybird genus is narrow distribution, many genera only distribute in a single habitat The most distribution genera are Coccinella, Coelophora and Cheilomenes). The group of grass-plot and stream side have the highest similarity of species composition (55.18 percent). The similarity of lspecies composition between other habitats are low (less than 50 percent). The species composition of sladybirds in disturbed forest and stream side is completely different (SI=O).
