At various localities in Hokkaido where two close relatives (D. sordidula and D. pseudosordidula) of the streamside drosophilid flies are absent or rare, local variation of the habitat preference of the streamside drosophilid flies was investigated by modification of the spatial microdistribution of neighboring streamside species to the vacant space which was occupied by D. sordidula or D. pseudosordidula in the central part of Hokkaido. In general the habitat preference of each streamside dweller was stable in such localities, but two streamside dwellers (D. moriwakii and D. lacertosa) which have rather wide habitat preference in the central part of Hokkaido showed small modification in the vertical microdistribution.
