The first record of odonata fauna in the Island Garden City of Samal is presented with comparison to other small islands in the Philippines. Opportunistic and photo documentation were employed in all fluvial systems surveyed between April 2014 to April 2015. Thirty one (31) species belonging to 7 families and 22 genera was recorded. Twelve species (12) or 39% are zygopterans and 19 species or 61% are anisopterans. A relatively low level of endemism (35%) is recorded which is attributed to the different habitat modifications of its fluvial systems. Kroeber’s percentage of similarity revealed Island Garden City of Samal shares similar odonata species with Siargao and Saranggani Islands characterized by karst ecosystem with low lying topography. Creation of local policy to protect the head waters where most of the endemic species found is urgently needed.
