Relative Abundance and Status of Butterfly Species in Magway Environs, Myanmar
Hnin Hnin Wai, Nyunt Lwin, Thant Zin
Relative abundance and occurrence frequency of butterfly species in Magway environs was investigated during June 2014 to May 2015. A total of 63 species confined to 45 genera, among 5 families and accounted to a total of 4217 individuals were recorded. The highest percentage of common (C) species 30.16%, abundance (A) 9.52%, frequent (F) 14.29%, occasional (O) 26.98%, sporadic (S)11.11%, rare 9.52% were recorded. Catopsilia pomona showed the highest relative abundance (0.0930), followed by Eurema hecabe (0.0870), Catopsilia pyranthe (0.0839), Ixias pyrene (0.0654) and Appias libythea (0.0467) during the study period.According to the whole study area, 4 species were very common, 25 species were common and 34 species were uncommon. Relative abundance and occurrence frequency of each butterfly species may be related to availability of food source, habitat condition and environmental condition. Thus, this study was partially informed the habitat health and biological diversity of Magway environs.
