Assessment of odonata and lepidoptera fauna of the University of Mindanao Matina, Davao City, Philippines

Abstract

Under the umbrella of the “Biodiversity assessment of the University of Mindanao (UM), Matina Campus” a rapid assessment of Odonata and Lepidoptera fauna was conducted between October 2016 and November, 2017. Opportunistic sampling and photo-documentation was conducted in three sampling areas: grassland, mini forest, and open landscapes near the college buildings. Nine species of Odonata were documented where the mini-forest has the highest species richness and open landscapes near the buildings have the poorest. One Philippine endemic Odonata species Coeriagrion lieftincki was found inhabiting the fluvial systems near the grassland. At present, this endemic species is considered least concern with stable population in the wild. Fifteen species of Lepidopterans were documented where the highest species richness was observed near the professional school. Majority are oriental species with one Philippine endemic Hypolimnas bolina philippensis. The minimal number of Odonata and Lepidoptera within the campus can be attributed to its severely disturbed fluvial systems limiting the survival of endemic species paving the way to more tolerant oriental species. The low species richness of Lepidoptera can be attributed to the low diversity of angiosperms in the campus serving as their host and food plants. The present microhabitat within UM Matina campus is not suitable haven for endemics.
