Diversity of Dragonfly Communities at Two Habitats in Negeri Sembilan

Abstract

Kuala Pilah and Batu kikir are located in Negeri Sembilan, Malaysia. The changes of flora and fauna community have always been related with the anthropogenic activities. This study was conducted in order to determine the species diversity of dragonfly within two different habitats in Negeri Sembilan. The sampling was carried out from August 2013 to October 2013 at two habitats comprising of UiTM Forest Reserve (Kuala Pilah) and Kampung Lonek Paddy Field (Batu Kikir). A total of 164 individuals of dragonflies were collected, which comprise of 14 species. For Kuala Pilah, a total of 11 species with 62 individuals were collected while for Batu kikir, a total of 9 species with 102 individuals were collected. Family Libellulidae was the dominant family that indicates 99 % of the total collected followed by one percent of total collected by Family Gomphidae. The highest total number of dragonfly individuals was shown by Potamarcha congener with 52 individuals that indicate 32 % of total collected while the least number of individuals was shown by the species of Orthetrum chrysis, Tholymis tillarga, and Ictinogomphus decoratus with one individual that indicate only one percent, respectively. Thus, there was high species diversity (H′ = 1.9), high species richness (R = 2.423), and high species evenness of dragonfly (E = 0.792) in UiTM Forest Reserve as compared to Kampung Lonek Paddy Field.
