| Drifting aquatic insects were collected with using drift nets in the middle reaches of the Paenae stream. a tributary of the Naktong River in Korea, in four seasons from August 1989 to May 1990. During the study period, 6 orders and 31 families were collected. Drifted insects were the most diverse in autumn, while the number of collected individuals was the highest in spring. The abundant groups were the primary consumers such as Ephemeroptera and Diptera including Heptagenidae, Baetidae, and Chironomidae. The secondary consumers such as Plecoptera and Trichoptera, and the burrowers, Ephemeridae and Odonata were collected less than the primary consumers. Generally the first dominant species belonged to Ephemeroptera such as Pseudocloeotz sp., Heptagenia sp., and Baetis sp, In four seasons Ephemeroptera appeared more abundantly in drift(62%) than benthic samplings(33%). Diptera occurred similarly in drift and benthic samplings at 22%. Plecoptera and Trichoptera were collected at 4% and 11%, respectively, and appeared less than in benthic samplings. In functional groups collectors and scrapers were collected more than shredders and predators in drifts. In habit groups clingers and swimmers were present more than sprawlers and burrowers. |
