Abstract

Faecal analysis was carried out to identify the diet composition of Eptesicus serotinus after collecting the faeces from 25 female bats. Five bats were captured at a bridge where a colony of E. serotinous was found in Andong city, Gyeongbuk, every month from May to September 2014. A total of 100 faeces were collected and the parts of insects obtained from the faeces were examined using a high-resolution microscope (50 ${\times}$ binocular microscope) and then the orders of the insects were identified by the characteristics of the parts of the insect (mouthpart, leg, wing, antenna, elytra, etc.). According to the results of the faecal analysis, 4 orders: Coleoptera, Hymenoptera, Diptera and Hemiptera were used as food resource of E. serotinus. Coleoptera was found in May, July, August, and September. Interestingly, only Coleoptera were found in May and July. Hemiptera, Diptera, and Hymenoptera were found to be used as food resources in September, June, and August.

문둥이박쥐(Eptesicus serotinus)의 먹이원 구성을 파악하기 위하여 총 25개체의 암컷 성체로부터 배설물을 수집하여 분석하였다. 박쥐의 포획은 경북 안동시의 문둥이박쥐 집단 서식지가 확인된 교량을 대상으로 하였으며, 2014년 5월부터 9월까지 매월 5개체를 대상으로 하였다. 총 100개의 배설물이 수집되었으며, 고배율 현미경(50 ${\times}$ binocular microscope)을 이용하여 곤충의 목(Order)별로 구기(mouthpart), 다리(leg), 날개(wing), 더듬이(antenna), 딱지날개(elytra) 등 구분할 수 있는 특징을 이용하여 동정하였다. 배설물 분석결과 문둥이박쥐의 먹이원으로 이용된 분류군은 딱정벌레목(Coleoptera), 벌목(Hymenoptera), 파리목(Diptera), 노린재목(Hemiptera) 등 4개였다. 먹이원 가운데 딱정벌레목은 6월을 제외하고 5, 7, 8, 9월 모두에서 확인되었으며, 특히 5월과 7월에는 오직 딱정벌레목만 확인되었다. 그 외 노린재목, 파리목, 벌목은 각각 9월, 6월, 8월에 먹이원으로 이용되는 것으로 나타났다.
