Seasonal changes in the amount of flesh intake by colonies of a polistine wasp, Polistes chinensis antennalis PEREZ, were assessed. First, the cumulative amount of flesh intake was estimated for various times. Seasonal changes of this amount were represented as follows : Y=10.332/[1+exp(3.410-0.06354T)], where Y is the amount of flesh intake in g dry weight per colony, and T is the day from May 31. Then seasonal changes in the amount of daily flesh intake per colony were estimated from the changes in cumulative amount mentioned above. The amount of flesh intake per colony per day, which showed its peak in late July, was larger in late July than in other periods. The mean maximum value was estimated to be 164 mg dry weight. Seasonal changes in the amount of flesh intake at a population level were also evaluated for a hypothetical population with varying rates of colony survival.
