Species diversity and habitat preference of butterflies (Insecta: Lepidoptera) in Inani Reserve Forest of Cox’s Bazar, Bangladesh

Butterflies of the Inani Reserve Forest were studied between May 2014 and May 2015. One hundred twenty five species of butterflies belonging to 84 genera and six families (Hesperiidae, Papilionidae, Pieridae, Lycaenidae, Riodinidae and Nymphalidae) were recorded during this study. The highest number of species comprised Family Nymphalidae (38 species, 30.4%) followed by Lycaenidae (35 species, 20.8%), Hesperiidae (26 species, 20.16%), Pieridae (16 species, 12.8%), Papilionidae (9 species, 7.2%) and the Family Riodinidae comprised the lowest (one species, 0.8%). The abundance of recorded butterflies was calculated in term of Very Common (20 species), Common (29 species), Uncommon (32 species), Rare (23 species) and Very Rare (21 species). The butterflies preferred different types of habitat (viz., Grass Land, Crop Land, Open Forest, Scrub Forest, Dense Forest and Bamboo Patches). Thirty species of butterflies were regularly observed in all kind of habitats, 69 species preferred multiple habitats (8 in 4 types, 24 in 3 types and 38 in 2 types of habitat) and 25 species were recorded only in a single type of habitats. Mud-puddling of 36 species were also observed. During this study, Zinaspa todara (Family: Lycaenidae) was the first time record in Bangladesh and Euploea doubledayi (Family: Danaidae) was recorded after 150 year later.
