초록
In an effort to restore the amphibians in urban freshwater system the characteristics of feeding activity of Rana rugosa living in Gyeonggi-provinces (Yangpyeong-gun and Namyangju-si) was analyzed from 2013 to 2014. The stomach contents of R. rugosa was analyzed non-invasively and compared to organisms captured by sweeping and trapping in their habitat. As a result, Hymenoptera and Cleoptera were primarily preyed by R. rugosa. Particularly, the proportion of Formicidae was more than 98% among the preyed Hymenoptera. Trapped insects in the habitat of R. rugosa’s in Namyangju were Hymenoptera (58%, Formicidae 99%), Collembola (17%), Orthoptera (10%) and Diptera (9%) in order in order. In Yangpyeong, trapped insects were Collembola (49%), Orthoptera (14%), Arachnida (9%), Diptera (9%), Cleoptera (7%) and Hymenoptera (3%). Even though Hemiptera and Diptera species are abundant in the streamside zones, R. rugosa could easily hunt Formicidae or Coleoptera on rocks or grassland at streamside. R. rugosa consume small sized ground-insects that are easily found rather than searching for the specific prey. Prey resource of urban stream may be not a limiting factor of R. rugosa inhabitation.
Abstract
In an effort to restore the amphibians in urban freshwater system the characteristics of feeding activity of Rana rugosa living in Gyeonggi-provinces (Yangpyeong-gun and Namyangju-si) was analyzed from 2013 to 2014.

As a result, Hymenoptera and Cleoptera were primarily preyed by R. rugosa. Particularly, the proportion of Formicidae was more than 98% among the preyed Hymenoptera. Trapped insects in the habitat of R. rugosa’s in Namyangju were Hymenoptera (58%, Formicidae 99%), Collembola (17%), Orthoptera (10%) and Diptera (9%) in order in order.
