  • Because insect visitors was different depending on decomposition stage, dipterans occurred on chicken carcasses depending on postmortem intervals were compared by abandoned sites and decomposition from a serial study on arthropod occurrence from carcasses as forensic indicator. Species occurrence and decomposition of carcasses were different depending on abandoned sites (forest hill, open field, stream, greenhouse and roof), seasons (spring, summer, fall and winter), and situation (burying and non-burying). Development of carcass decomposition was faster at all sites in summer, carcass in greenhouse in winter, and unburied carcasses. Although visiting time of blow flies (Calliphoridae) (Phaenicia sericata, Lucilia illustris, Lucilia sp., Chrysomyia pinguis, and Chrysomyia megacephala) was different depending on abandoned season, their adults were generally collected from carcasses within 2 days. However, there were no visited flies at fresh stage of buried carcasses. The flesh flies (Sarcophagidae) were collected from all sites and seasons, and much faster from unburied carcasses than buried carcasses. Those were collected earlier from carcasses in greenhouse than other sites and occurrence was also shorter. In greenhouse, occurrence time of flesh flies were different depending on season; spring and summer - from fresh to active decay stage, fall - fresh to active decay stage, and winter - advanced decay to remains stage. Calliphora lata, Tricerotopyga calliphoroides, and Aldrichana grahami were dominant species and occurrences were different from other flies. These flies were active mainly from fresh to active stage. Larvae of sarcophagid flies were occurred earlier than those of calliphorid flies on buried carcasses.
