Abstract
In nature and in the laboratory the large milkweed bug, Oncopeltus fasciatus (Dallas), has been observed to cluster in groups both when feeding and when not engaged in any apparent activity. In time-lapse photography studies of feeding behavior in the milkweed bug, Beck et al. (1958) found that only one bug could be used satisfactorily in a chamber, because when a number of bugs were present they clustered around one diet and obscured the feeding pattern under study. The present experiment was undertaken to determine whether this gregarious feeding behavior was necessary for maximum development and at what point crowding would become deleterious to development.
