Inventory and diversity of dragonflies (Odonata) at Kuningan Resort of Mount Ciremai National Park, West Java Province

Abstract

The presence of dragonflies regarding the sensitivity of nymphs towards environmental changes is considered a bioindicator that can indicate changes in water quality and the environment. The purpose of this study is to take inventory of the species and the diversity of dragonflies at the Kuningan Resort, Mount Ciremai National Park in several representative aquatic habitats. The dragonfly inventory technique used a modified line transect method with observation plots that are not limited by a certain distance or area but by a set time of 15 minutes for each plot observation. The results of the inventory obtained 24 species of dragonflies from 8 families, as many as 591 dragonflies consisting of 58.2% of common dragonflies including of suborder Anisoptera consists of Aeshnidae, Gomphidae, Libellulidae and 41.8% of needle dragonflies including of suborder Zygoptera consist of Platystictidae, Calopterygidae, Chlorocyphidae, Euphaeidae, Coenagrionidae. The dragonfly diversity index (H' = 1.94 – 2.32) (medium), the species richness index, or the values of Margalef 's diversity index (Dmg) ranged from 1.99 to 2.87 (low), the species evenness index ranges from 0.39 – 0.6)(low – medium).
