腐尸甲虫（Eusilpha japonica）是一种食腐动物，它在森林地面上漫游，寻找腐尸。采用带腐肉和不带腐肉的陷阱进行实地调查，考察腐肉气味对雪松林成虫的吸引效果。陷阱中捕获的甲虫的性别分布表明，腐肉气味可能比雄性更能吸引雌性。这种分布模式表明，雄性可能在寻找食物的同时也在寻找配偶。野外采集的成人每日食物摄取量在实验室测量。单身的雌性吃的肉是单身雄性的两倍。第一次产卵前的累积摄食量与窝卵数呈正相关，表明产卵前的摄食量至关重要。
The carrion beetle, Eusilpha japonica, is a carrion feeder that roams on forest floors searching for carrion. A field survey using pitfall traps with putrefied meat or without meat was carried out to examine the effect of carrion odor on the attraction of adults in the cedar forest. The sex distribution of the beetles captured in the pitfall traps suggested that the carrion odor might attract females more strongly than males. The distribution pattern showed that males might search for mates as well as for food. The daily food intake of adults collected in the field was measured in the laboratory. Lone females fed on the meat twice as much as lone males. A positive relationship between the cumulative quantity of food intake until the first brood and the clutch size suggested that the quantity of food intake during the pre-oviposition period was critical.
