Mihara, M.; Kurahashi, H.; Kondo, S.; Kawahara, S.

The nuisance fly Leptocera fuscipennis (Hal.) was studied in Tokyo Bay, Japan, at the sewage disposal site where it breeds abundantly. Adults were most abundant in mid-July and local residents were troubled by the flies between late June and late July. In 1972, work had begun to fill the site with sea mud and sludge previously mixed with sea water.
