Distribution of eggs after 24 h on the patches with food, P and R. Shown are the proportions of eggs on the two food patches R and P. a, d I. degenerans was the resident (released on patch R; Fig. 2), N. cucumeris the invader (released on patch Inv; Fig. 2). b, c N. cucumeris was the resident (released on patch R), I. degenerans the invader (released on patch Inv). *** indicates that the distribution (pollen patches vs. empty patches) in the treatment with both species differs significantly from that with one species (P < 0.001). Ns not significant. For abbreviations, see Fig. 2
