Example of plant partitioning by a territorial male and intruding females. This graph shows the relative frequency of feeding visits by territorial male P (= M, hatched) and intruding females (= F, solid) to H. caribaea plants on his territory. On nine of the 12 male territories studied, males and females differed significantly in their visits to plants (χ2 and exact tests of independence, p's < 0.05; striped bar, M, n = 167; filled grey bar, F, n = 102).
