A laboratory experiment followed the growth of a flour beetle (Tribolium sp.) population over time.  At first the population increased dramatically but later growth slowed and the population size leveled off. While food (the wheat flour in which they live) was abundant, it was noticed that flour beetles resorted to eating their own eggs when densities got high. What can we conclude about cannibalism in this species?
