Indonesia is a country that has high biodiversity, one of which is dragonflies. Dragonflies are an insect that has a fairly wide distribution, including rice fields, gardens, lakes, rivers and forests. This research aims to record and determine the value of the diversity of dragonfly species found in Lake Rano, Balaesang Tanjung District, Donggala Regency, Central Sulawesi Province. This research was carried out from February to April 2023 at Lake Rano, Balaesang Tanjung District, Donggala Regency, Central Sulawesi Province. The method used is the line transect method. Based on research results, the type of dragonfly found in Lake Rano, Balaesang Tanjung District, Donggala Regency, Central Sulawesi Province is in the medium category with a value (H') of 2.938. The species evenness index at the research location showed an overall result of 0.98. This condition shows that the evenness of species in Lake Rano is classified as good, meaning that the abundance of each species is evenly distributed in the location studied. The dominance index shows that the dominance of a dragonfly species can be seen in the largest number of a species compared to other species found. The dragonfly species found in the highest numbers in this study were Neurothemis manadensis, Othettrum glaucum and Otrthettrum pruinosum. Overall, the three dragonfly species were dominant.
