A total of 11 genera and 13 species belonging to 9 families of the dipterous insects were reared from feces of the great cormorant (Phalacrocorax carbo hanedae Kuroda) in Chita, Aichi Prefecture, Central Japan. Of the 13 species of flies reared, 3 were markedly predominant, Parasarcophaga similis (Sarcophagidae), Siphunculina nidicola and S. simulata (Chloropidae). Among these species, P. similis was the most dominant fly, which constituted 34.4% of the total, and reached the highest population in early December. S. nidicola (26.1% of the total) and S. simulata (22.8%) have also produced large numbers. The massive emergence peak of the former showed in early September, and the latter in early October. These 3 specific cumulative percentages amounted to about 83% of the total individuals. The emergence season of P. similis was from June to December, the longest period of all the reared species. Only one species, Anthomyia illocata (Anthomyiidae) was commonly found among the known 5 species which were reared from cormorant feces in Japan. Megaselia scalaris (Phoridae) and Allotrichoma nigriantennalis (Ephydridae) were investigated and found to emerge from small animal excreta for the first time.
