The purpose of this paper is to study the food sharing between two species of ants with similar food requirements. 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. Ct : the number of baits occupied by Camponotus at time t.

(1)京大植物園の草地に生息するアリに砂糖水を与え、この餌へのアリの集まり方から、餌の分配のされ方を調べた。(2) 砂糖水には11種のアリが集まってきたが日中に大部分の餌を占めたのはクロヤマアリとクロオオアリであり、この2種を実験の主要な対象とした。(3) 砂糖水を与えると、まずクロヤマアリが大部分の餌を占め、遅れてクロオオアリが来たがクロヤマアリの占めた餌を奪い時間経過に伴いクロオオアリが多くの餌を占めるようになった。(4) クロヤマアリとクロオオアリの餌の占め方に関するモデルを作り、得られたデータを検討した結果、地温の著しく高くなる時刻を除いて次式に比較的よく合うことがわかった。(dF_t)/(d_t)=a(m-F_t-Ct)(dC_t)/(d_t)=b(m-C_t)F_t, C_t，はそれぞれクロヤマアリとクロオオアリが占めた餌の数で、m，a，bは定数５）このモデルを用いて動物性の餌分配の様式を予測できるかどうかを検討した。
