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.

This place which mostly formed by dune which in the rainy season is flooded by water, thus forming a pool called wet dune slack. Damselflies (Odonata: Zygoptera) are closely related to the occurrence of water. The aim of this research is to compare the diversity of damselflies in canopied and non-canopied areas on Gumuk Pasir Parangkusumo, Yogyakarta, Indonesia. The method which used in this research was the descriptive method with active exploration techniques around the wet dune slack to the vegetation formation. The result showed that there are 4 species of damselflies in canopied area and 5 species of damselflies in non-canopied area. The diversity index (H') is 1.18 in canopied area and 1.01 in non-canopied area. The highest relative abundance of the species in canopied area is Ischnura senegalensis (45,65%) whereas in non-canopied area is Agriocnemis pygmaea (62,34%). The non-canopied areas has conditions more suitable for damselflies's life.

Ketersediaan informasi mengenai kemelimpahan populasi walangsangit di Daerah Istimewa Yogyakarta sangat minimal. Tujuan penelitian ini untuk mengetahui kemelimpahan populasi walangsangit, serta untuk menginventarisasi keanekaragaman jenis walangsangit pada ekosistem sawah dengan ketinggian 20, 29, 44, 58, 99, 141, 206, 300, 428, 478, dan 570mdpl di Daerah Istimewa Yogyakarta. Teknik sampling yang digunakan dalam menentukan daerah sampling adalah teknik sampling bertujuan (purposive sampling technique). Area persawahan tidak terawat memicu pertumbuhan berbagai spesies tumbuhan lain yang potensial menjadi tanaman inang walangsangit. Ketidakseragaman pola tanam, perbedaan varietas tanaman padi dan resistensi hama terhadap insektisida memicu tingginya kemelimpahan populasi walangsangit yang ditemukan pada ketinggian 428mdpl yaitu sebesar 10326 individu/ha (1,0326 individu/m2). Pada ketinggian 29mdpl, area persawahan memasuki musim tanam kedua sehingga kemelimpahan populasi walangsangit menjadi rendah yaitu sebesar 140 individu/ha (0,014 individu/m2). Kemelimpahan walangsangit pada ketinggian 20, 44, 58, 99, 144, 206, 303, 478, dan 570mdplmasing masing 642, 246, 437, 3457, 2033, 1050, 2377, 1383, dan 1640 individu/ha. Walangsangit yang ditemukan pada berbagai ketinggian di Daerah Istimewa Yogyakarta tergolong dalam spesies Leptocorisa oratorius.
