Microhabitat utilization is an important factor for species diversification. This study examined the microhabitat utilization of leaf-dwelling pholcids. The occurrence of 241 collected samples showed different degrees of plant occupancy as evaluated by Bodenheimer Constancy: Schismatoglottis sp. (constant; 51.25%), Homalomena philippinensis (accessory; 25%), Curculigo latifolia (rare; 11.86%), Aglaonema sp. (rare; 11.25%) and dicot seedling, Dillenia megalantha (rare; 0.63%). Concentration of Relative Dominance (CRD) of leaf-dwelling pholcids per plant species showed that Schismatoglottis sp. had the highest percentage (48.96%). Analysis of foliar parameters indicated certain level of association with the occurrence of leaf-dwelling pholcids. Chi-square test showed that there is a significant association between Schistomaglottis sp. and dicot seedling, Dillenia megalantha.
