GARCIA, MAY V. Diversity and Habitat Characteristics of Dragonflies and Damselflies in Selected Lowland Areas of Cavite. Undergratuate Thesis. Bachelor of Science in Biology, Cavite State University, Indang, Cavite May 2017. Adviser: Jonathan R. Digma. Adult dragonfly and damselfly collection was conducted in selected rivers of Cavite from January to March 2017. All collected dragonfly samples belongs to family Libellulidae while four families of damselfly were identified. Damselfly families includes, Chlorocyphidae (37.89%), Coenagrionidae (25 95%), Platycnemididae (3.34%) and Euphue.idue (0.31 0/0), The habitat characteristics and selected physico chemical characteristics of the nymph habitat were recorded, these environmental parameters were elevation (62111 to 378m), air temperature (27.3 o c to 31.8 o c) and humidity (23% to 79%). The six physico-chemical parameters like water temperature (24 65 oc to 31 8 DC), pH (7.16 to 7 95), DO (6.81 to 7.93), salinity (0 146 to 155ppm), conductivity (284 to 289 uS) and TDS (197 to 213ppm) were also evaluated. The relationship between dragonfly and damselfly family and important environmental parameters such as humidity and water temperature were found to have significant correlation, which suggests that humidity and water temperature influence odonate survival. Species — habitat association showed that family Libellulidae are mainly associated with the lowland areas of Cavile as evindenced by higher water temperature and lower humidity while family Cholorocyphidae, Coenagrionidae, Platycnemjdidae and Euphaeidae showed its association with the upland area of Cavite as evidenced by increasing humidity and lower water temperature, thus different abiotic condition in the study area have supported odonate smvival and distribution.
