The altitudinal distribution of flies on Mt. Fuji in summer season

Abstract

1. Investigation of the altitudinal distribution of flies was made on the Mt. Fuji from 28th to 30th of July, 1964. 2. Eight collecting stations were selected, where flies were gathered with 2 cage traps uaing horse minced flesh as the bait. 3. Collected flies were identified and counted. The results were shown in figures and in a table. 4. Each fly species had its own distributional range, which was determined chiefly by climate, flora and the presence of the breeding place, particularly human dwellings. 5. There were 4 altitudinal zones of fly distribution : (1) 0-500m. (2) 500-1, 500m. (3) 1, 500-2, 500m. (4) Over 2, 500m.
