Diversity of Butterflies on Different Ecosystems and Seasons

Abstract

Indonesia is a tropical country that has two seasons, dry and wet. These climate conditions make Indonesia have mega biodiversity. The organism that has high diversity is an insect. Butterflies are exotic insects for diversity. This research aims to calculate and compare the abundance, diversity, richness, evenness, and similarity of butterfly species in several different ecosystems and seasons, and analyze the effect of seasonal differences on their abundance. The sampling method used the time search method on primary forest, secondary forest, plantation, and paddy field on the border of South Sulawesi (Pinrang Regency) and West Sulawesi (Mamasa Regency). The results showed that in the dry season, there were 156 species from 25 families of butterflies, while in the wet season, 74 species from 10 families of butterflies found. Three species of butterflies are protected and nine endemic species.
