Five species of hover wasps (Hymenoptera:Vespidae:F) are included in the faunal list for Mount Makiling, Laguna, Philippines. They are Eustenogaster luzonensis (Rohwer), Liostenogaster varipicta (Rohwer), Parischnogaster depressigaster (Rohwer), P. nigricans (Cameron), and P. timida (Williams). E. Luzonensis was not recovered or collected during this study. On the other hand, P. nigricans, known to occur in Luzon but was not included in the previous works, is now confirmed to be present in the mountain, particularly in the lower and middle slopes. The nests of the four species collected were also studied, photographed, and described. Each nest exhibits differences in architecture, which may also be reflective of other characteristics such as morphology. The mandibles of the wasps were dissected and photographed, and their length, width, and height were measured. Additional variations in characters were added in each description. The nests can be differentiated from one species to another, with those of P. nigricans being the most flexible. Hence, nest structure may also be identified according the wasp species that constructed them L. varipicta which uses mud, has longer and thinner mandibles compared to vegetable material users like Parischnogaster spp.
