Abstract Odonata (dragonfly and damselfly) are important predators of disease vectors and agricultural pests. They are also useful as bioindicators of freshwater ecosystems due to their sensitivity to anthropogenic change. This study was conducted to assess the species composition of Odonata in the vicinity of Bolyok Falls in Brgy. Lubilan, Naawan, Misamis Oriental, Philippines. Field sampling was conducted in three sampling sites on March 9, 2019, using sweep netting and hand-picking methods. A total of nine species were identified belonging to seven families and seven genera of Odonata. Risiocnemis appendiculata was the most abundant Odonata species. The endemism is high at 77.78% with six species endemic to the Philippines and one endemic to Mindanao. The overall species diversity index of Bolyok Falls is very low at H’ = 1.59. Identified threats of odonates include land clearing for agriculture and expansion of resort facilities near the sampling sites. The high levels of endemism indicate that the area is vital for odonates. Thus, the formulation of mitigation measures for conservation and preservation of species is needed in the area.
