SUMMARY The nesting behaviour of two species of ant ( Cataglyphis bicolor and Messor wasmanni ) is investigated by regarding their nests as a bivariate spatial point pattern. When the nests of each species are considered separately, those of the Messors are found to be more regularly spaced than would be the case if they were located at random. There is no strong evidence of such inhibition between the Cataglyphis nests. The possibility that the positions of the nests of Cataglyphis ants are dependent upon those of the Messors is suggested on biological grounds, and is investigated by various methods. No clear evidence for such an association is established.
