Comparison of Damselfly (Odanata: Zygoptera) diversity in wet dune slack habitat with canopied and non-canopied areas of Gumuk Pasir Parangkusumo, Yogyakarta, Indonesia
Gumuk Pasir Parangkusumo is one of the unique eolian ecosystem in Yogyakarta.
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.
