Light traps were loceted 0 m (St. 0), 1,375m (St. 1), 2,700m (St. 2), 3,650m (St. 3), 4,600m (St. 4) and 5,325m (St. 5) from the outlet stream of the lake. A total of 105,874 adults were collected, and the sex ratio of the adults was biased to female throughout the study period except on July 23. The daily mean abundance of adults was highest at St. 0 (9,368.4 ± 8,569.1 ind. day-1) and declined rapidly the further the distance from the outlet of the lake. The mean relative proportion of the daily abundance at St. 1-5 to that at St.0 was less than 5%. In addition, there was a significant negative correlation between the daily abundance at a site and the distance from the lake outlet to the site. These results suggest that adult C. brevilineata can move at least 5,325 m, although most adults do not move so much., Article, 環動昆.19(3):133-140(2008)}, pages = {133--140}, title = {Distribution of adult Cheumatopsyche brevilineata (Trichoptera: hydropsychidae) along the shore of Lake Suwa, Japan.}, volume = {19}, year = {2008} }
