논에 서식하는 거미의 밀도를 조사하기 위해 1975년 11월 4일부터 11일 사이에 전북지방의 답작지대에서 의 면적내에 서식하는 거미를 채집하여 다음과 같은 결과를 얻었다. 1. 늦가을 논에 서식하는 거미의 우점종은 황갈애접시거미 (Gnathonarium dentatum), 황산적거미(Piratasubpiraticus), 혹황갈애접시거미(Gnathonarium gibberum), 등줄애접시거미(Oedothorax insecticeps)이다. 2. 단위면적당의, 평균서식밀도는 이리에서 125 마리, 진안 102마리, 부안 133마리, 대장 58마리였다. 3. 논거미로서 혹황갈애접시거미 (Gnathonarium gibberum), 착살가랑잎꼬마거미 (Enoplognatha japonica), 톱니애접시거미(Erigone prominens), 혹갈애접시거미(Erigonidium graminicola) 여덟점꼬마거미(Theridion octomaculaculatum) 들늑대거미 (Lycosa pseudoannulata), 가는줄맛거미(Dolomedes angustivirgatus) 등의 7종이 추가되어 우리나라의 논거미는 55종이 된다.

The present report is dealt with the spiders which are caught within a space of of rice paddy field where was harvested the rice crops in Jeonbug district, from November 4 to 11, to 1975. 1. Twenty-one species of spiders were caught at the area during the period. Of these the dominant species were Gnathonarium dentatum, Pirate subpiraticus, Gnathonarium gibberum, Oedothorax insecticeps etc. 2. Average density of spiders within a space of of rice paddy field where rice crops was harvested was as follows: 125 at Iri, 102 at Jinan, 133 at Buan, and 58 at Daejang. 3. The scientific names of spiders which were caught in rice paddy field for the first time in Korea were Gnathonarium gibberum, Enoplognatha japonica, Erigone prominens, Erigonidium graminicola, Theridion octomaculatum, Lycosa pseudoannulata, Dolomedes angustivirgatus. As the result of this survey, fifty-five species of spiders were recorded in rice paddy field of Korea.
