Comparison of the phenological characteristics of the three species P. populi , P. bursarius and P spyrothecae. (A) the emergence patterns, (B) the patterns of gall opening, and (C) the patterns of gall mortality (death of all the individuals within the gall). Splines are fitted to the data of P. populi and P. bursarius and regression curves are plotted for the combined data for P. spyrothecae. The data from the different field sites from which P. spyrothecae was sampled (CW: Cement Works, LP: Leys Playing Field, PS: Pembroke Sportsground, CF: Coton Footpath) are identified by the unique triangular symbols indicated in the legend.
