A total of 1182 adult beetles belonging to twelve species of the family Silphidae were caught with meat-baited pitfall traps from May to October, 1983,on the Ishikari Coast, northern Japan. Spatiotemporal distributions of five dominant species, which were comprised of two silphines and three nicrophorines, were determined. There was a significant difference in resource use among all but one pairwise combinations of the dominant species in either habitat or season dimensions, or a combination of both. This finding was discussed in relation to the food types and food habits of the silphid beetles.
