The fauna and distributions of the black flies in Yamanashi Prefecture were investigated by collecting the early stages of flies from the streams. The survey was conducted with 32 streams in February and March of 1971. The water temperature of the streams ranged from 5°to 8℃ during the period of the observation. On 33 spots out of 57 investigated the aquatic stages of the black flies were collected. They were 14 species belonging to two genera as shown in the following; 1) Prosimulium kiotoense 2) Simulium uchidai 3) S. subcostatun 4) S. mie 5) S. kobayashii 6) S. aokii 7) S. iwatense 8) S. bidentatum 9) S. japonicum 10) S. arakawae 11) S. suzukii 12) S. rufibasis 13) S. kawamurae 14) S. sp. A Among these the six species, that is P. kiotoense, S. subcostatum, S. mie, S. kobayashii, S. aokii and S. sp. A. were collected for the first time in the Prefecture. So far 12 species had been recorded in the district, therefore the fauna come to include 18 species of three genera. The hitherto unkown larvae of S. kobayashii were collected by the authors at one spot in a concrete ditch running to the River Fuji. The distribution characteristics of several species were discussed.
