In the present study, we analyzed ecological functional groups of diverse hymenopteran families from five different vegetation stands in the Gwangneung forest. Hymenopterans were collected using three different traps from March to October 2015. Pollinators were a dominant group from March to May and declined significantly after that period. Parasitic group made major peaks from April to May and made another small peak in August. Predatory group reached to a peak in April and July respectively but appeared to be active even in October when all the other groups mostly disappeared. The vegetative communities were ordinated with the hymenopteran family assemblages using the Nonmetric multidimensional scaling (NMDS). The result of NMDS analysis showed that the community structure of the hymenopteran functional groups from the Quercus rubra stand is different from those of the other stands.
