The Diversity of Odonata in Parangkusumo Sand Dune Yogyakarta, Indonesia

Parangkusumo sand dune is a one of unique eolian ecosystem in Yogyakarta. The study on the species diversity of dragonflies in this habitat is still limited. The main purpose of this research was to observe the dragonflies species diversity in Parangkusumo sand dune, Yogyakarta, Indonesia. The collection of dragonflies was done by aerial collection using sweep net. The specimens identification was done in Entomology Laboratory, Faculty of Biology, Universitas Gadjah Mada based on the morphological characters of the adult stage. The results showed that there were 22 species of Odonata, including 17 dragonflies (Anisoptera) and 5 damselflies (Zygoptera). The diversity index (H') was 2.51 which inferred medium diversity. Several species such as Anax guttatus, Lestes praemorsus and Tramea transmarina were found to be endemic species. The highest relative abundance of the species was Orthetrum sabina (21.79) and lowest abundance of species is Orthetrum chrysis (0.14). Parangkusumo sand dune has medium dragonfly diversity, thus it is recommended this habitat need to be conserved.
