Abstract

Dragonflies have an important role in habitat for maintaining the balance of forest ecosystem and as predators to small insects such as like moths mosquitoes and plant pests. The purpose of this study was to determine the composition and diversity of Anisoptera dragonflies (Odonata) in three types of habitat in the Ghimbo Potai Indigenous Forest. This research was conducted from January to Ferbuary 2020 with a purposive method. Data collection used LTC (Linear transect count) in three habitats namely aquatic area, open forest and forest edges. A 200 m transect was made for sampling and observation along 10 m right and left of the transect. The results of research on three types of habitat found two families namely Libellulidae (13 species) and Gomphide (1 species) of 567 individuals. The highest value of relative abundance was found in species of Orthetrum sabina that dominated all habitats. This study conclude that the diversity index range was 2,18-2,49 and aquatic habitat had the highest percentage of diversity and evennens
