A sandy grassland on the campus of the Kyoto University where Formica japonica and Camponotus japonicus coexisted was selected as for experiments. The species and individual numbers of ants swarming on baits were studied every 5-10 minutes after the setting of 25 sugar ources on the ground. The numbers of baits occupied by two species of ants were shown by the following equations. (dFt)/(dt)= a(rn - Ft -Ct), (dCt)/dt=b {m - Ct) a, b, m : constant Ft : the number of baits occupied by Formica at time t.
